Types of DC Motors

There are various thruster underwater motor available, each designed to satisfy particular operational requirements. The two most often used varieties are brushed and brushless motors. Brushed thruster underwater motor are simple to operate and reasonably priced since they provide current to the motor. However, they need frequent maintenance to replace worn brushes. Conversely, brushless thruster underwater motor removes the need for brushes by adopting electronic commutation, therefore producing longer life spans and more efficiency. Furthermore, coreless thruster underwater motor are well known for their lightweight and high-speed performance, which are perfect for uses when weight is a major consideration. Every type of thruster underwater motor has special benefits that can be used depending on the particular need of the project.

Features and Functions of DC Motors

thruster underwater motor have a spectrum of features that make them essential in many uses. Their capacity to offer continuous speed under different load conditions is one of their main features; tasks needing accuracy depend on this. Furthermore, by providing reversible operation, they enable bidirectional movement, which is quite helpful in conveyor systems and robotics. Their speed control ability is achieved by voltage control or pulse-width modulation which allows users to change motor speed depending on particular requirements. thruster underwater motor simple design makes it fit for use in portable devices and small machinery since it lets one easily integrate into limited areas. Moreover, its strong building guarantees dependability even in challenging surroundings.

DC Motors Materials and Components

The building of thruster underwater motor calls for several materials and components that support their lifetime and performance. Usually composed of laminated steel, the core of the motor reduces energy loss resulting from eddy currents. The great conductivity of copper windings guarantees effective power transmission. Often built from sturdy materials like aluminum or steel to resist mechanical stress and offer defense against environmental elements, thruster underwater motor is housed either permanently or electromagnetically, magnets are essential parts creating the magnetic field required for operation. Furthermore, they are included within the brushless field of power transmission. thruster underwater motor is essential since it translates electrical energy into mechanical motion. These motors are distinguished by their direct current operation, which enables users to precisely adjust torque and speed. Because of its dependability and efficiency, thruster underwater motor finds great usage in anything from consumer electronics to industrial machines. Their adaptability makes them vital parts of systems needing regulated movement, like robotics and automation. Unlike their AC counterparts, thruster underwater motor have the benefit of steady and smooth operation qualities that are very vital in applications requiring great accuracy.

Effective Utilization of DC Motors

Understanding the capabilities and restrictions of thruster underwater motor will help in maximizing its advantages. Good installation is vital. It ensures the motor is positioned precisely and securely to avoid unnecessary bearing stress. Using suitable voltage levels can help users minimize harm and maximize performance when linking thruster underwater motor to a power source. The longevity of the motor depends on regular maintenance including lubrication and cleaning to guarantee the dependability of operation. Utilize drives or controllers specialized for thruster underwater motor to make exact adjustments in applications needing varying speeds. Thermal control is also crucial since too much heat can destroy motor components and lower efficiency. Following these rules helps users to rightly utilize thruster underwater motor for a variety of purposes.

Selecting the Correct DC Motors

Choosing the suitable thruster underwater motor for different requirements calls for various important factors. First, check the system's power needs to guarantee suitability for the voltage and current ratings of the motor. Another important consideration is the operational environment; for situations with high moisture or dust levels, for example, thruster underwater motor with certain protective enclosures may be needed. Moreover, the weight and size of the engine should be taken into account, particularly in cases of limited space or involving portable devices. The kind of load the motor will run also affects the decision since different uses may need different degrees of torque and speed. Through carefully evaluating these elements, users can select a thruster underwater motor that fits their operational requirements.

Furthermore, the knowledge of thruster underwater motor lifetime and efficiency is crucial. For uses where maintenance access is limited, brushless motors, for example, usually offer greater efficiency and longer service life than brushed motors. Furthermore, it is crucial to assess the motor's thermal management capacity since good heat dissipation greatly improves lifespan and performance. Integration of complex control systems and feedback mechanisms may be helpful in applications needing exact control. Giving these factors top priority will help in deciding wisely and guarantee that the selected thruster underwater motor satisfies a set of needs.

Q&A

In which way do brushed and brushless DC motors mostly differ?

Brushed thruster underwater motor employs brushes to move electrical current, which can cause wear and call for regular repair. Conversely, brushless thruster underwater motor use electronic commutation, therefore negating the need for brushes and so lowering maintenance requirements. Usually, brushless motors have a longer lifespan and better efficiency than brushed motors.

For what purpose should users choose a DC motor size?

The particular criteria of any application, including the space available for installation and the power required to operate the load should guide the size of thruster underwater motor. The motor should be able to provide the required torque and speed without exceeding its running capacity.

Are harsh climatic circumstances something DC motors can run in?

Indeed, some thruster underwater motor are meant to work in demanding surroundings. They may include protective enclosures or coatings shielding against moisture, dust, and temperature extremes. Choose a motor that is rated for the particular environmental conditions it may come across.

Within DC motors, what is the function of controllers?

Controllers control direction, speed, and torque, therefore enabling thruster underwater motor to run as it should. Through various techniques, they allow exact adjustments that include pulse-width modulation and incorporation of feedback systems for maximum control. Maximizing motor performance requires the correct controller choice.

Ten 260Kw submersible motors with SS316 construction to CTC Marine Projects based in Teeside, England. The motors will be used by CTC on their subsea plough and trenching vehicles worldwide.

ROV 260kW Silvercrest/SME Pump Motor under construction.

The 260kW/ V / 60Hz / 2 pole pump motors (designed specifically for use in the horizontal axis) were fitted with shafts at both ends, in order to mate with three tandem mounted hydraulic pumps on one end and a Hayward Tyler M6 single stage water pump-set on the opposite end. In this 260kW model, rather than using the pivot shoe arrangement, typical of vertically oriented pump-sets, heavy duty tapered roller bearings were fitted to the rotor to manage the water pump induced end-loads. Thus giving a calculated bearing life in excess of 11,000 hours, even when used in the horizontal axis. Depth rating on each motor is 10,000 meters, with oil filled compensation. Motor housings are 316 stainless steel, with Mylar coated windings (the ultimate in winding coating technology) being used in each motor at the request of CTC, giving an insulation rating of >16kV at a temperature of 140 degrees C.

Silvercrest/SME will bespoke manufacture virtually any shape and size of submersible motor required for subsea operations.

There are two common methods of construction available: -

Stainless steel construction, or Marine Grade aluminium that is Black anodised to resist corrosion. These motors are usually oil filled and pressure compensated. Common operating voltages are between 300 volts and volts - even for small 5kW motors.

6,000vac and 11,000vac motors also available by special request.

Silvercrest/SME will bespoke manufacture virtually any shape and size of submersible motor required for subsea operation

Certain subsea motors can operate down to depths of 10,000 meters.

SME manufactures new Submersible, Subsea, and Rov motors.

We manufacture our own laminations, designed specifically to meet the individual requirements of each customer. We do not buy off the shelf standard rotor sets and fit them in a housing, as some other manufacturers will often do. As a result our motors are more efficient and generally ightly smaller, in both diameter and length, than our nearest competitors for any given power

rating.

Silvercrest also offer a range of ‘standard’ motors for use in well-established underwater installations, such as the more popular classes of Rov and subsea ploughs.

Rov and Subsea Plough and Trencher Motors.

Silvercrest offer an established range of Rov motors ranging from 5HP to 500HP. All of these motors are available in either SS316 or Hard Anodized Aluminium finish. We will also design and build submersible motors to suit your individual requirements and subsea project.

Our motors are in use with most of the major operators worldwide such as Saipem, SMD Hydrovision, Sonsub, CTC Marine Projects, Impresub, Fugro, Thales, MTQ, LD Travocean and Canyon Offshore.

Silvercrest will bespoke manufacture virtually any shape and size of submersible motor and submersible pump required for subsea operations.

AC-ROV. (Possibly the best small Rov in the market).

The smallest inspection class ROV in the market place (190mm fly through). The AC-ROV is more powerful, more robust and a more cost effective solution than all other ROVs in its class.

These facts however are secondary to the real capability of the AC-ROV. All underwater ROVs have a flight pattern that reflects the movement of an aeroplane (3 degrees of movement) - this means that when inspecting or observing a target the ROV must constantly move in and then away to take up a fresh viewing position. The AC-ROV however has the underwater flight pattern of a helicopter - this allows the ROV to hover, circle, rotate on its axis and move in any direction the target requires. This breakthrough is achieved by six internally housed thrusters that produce five degrees of movement.

With an operating depth of 75-100m, a total system carry case weight of under 15kg, and a service life of 200-300 hours at 100% duty (continuous full depth & full speed), the AC-ROV has been designed for inspection in hazardous and confined areas.

Manipulator

Slip ring reels

The AC-ROV has a two- function manipulator (option). The manipulator combines grip and full continuous wrist rotate via a ground breaking drive-train, resulting in the smallest two-function manipulator in the ROV market. Consisting of titanium, aluminium, stainless steel and plastic components, the AC-ROV micro-manipulator system comes completely integrated into its own bottom buoyancy block. There are no underwater cable connections thus limiting snagging potential, while the integrated nature of manipulator and block gives the system inherent strength and robustness - a feature demonstrated by all AC-ROV components. Simply remove the standard bottom block from your AC-ROV and fit the manipulator block, the manipulator is 100% interchangeable between individual AC-ROV units, giving maximum functionality and cost savings. Topside control is a thumb activated one handed joystick controller that simply connects directly to the control box without need for modification, with all manipulator operations viewed via the state of the art camera system. Two and three jaw options are available and customers can specify special gripper heads for specific jobs. Three screws secure the jaw assembly to the arm and change-out could not be easier.

Notes.

1. Flight assist controls include; Flight Freeze & Un-freeze / Progressive +/- Vertical Trim / Progressive +/- Pitch / 3 stage Power Increment. All these functions are programmed on the hand controller. Light dimmers are incorporated on the control box.

2. The AC-ROV thruster does not have a centre and the inward pointing blades do not meet. The full-bore unrestricted flow path maximises thrust and is relatively self-clearing in weed type environments.

3. The tether cable and connectors are field serviceable, given that the operator has basic electrician skills. Any damaged cable can be cut out and any remaining serviceable cable re-terminated and used again without the need for specialist cable moulding services.

4. Connect a PC or Laptop computer with video grabber, or a video recorder for video recording and data logging.

A computer is not required for normal operation nor included in the supply.

THE SEAEYE TIGER is widely regarded internationally as the standard observation and inspection ROV for operations to depths of metres in the offshore oil and gas industry. Its performance in strong currents, excellent handling and manoeuvrability are unsurpassed.

A Seaeye Tiger can be operated free swimming with up to 450 metres of umbilical or from a Type 2 or Type 5 TMS system to its full working depth.

Seaeye Tigers are open frame construction providing greater scope to fit additional accessories and more capable manipulators than 'eyeball' ROVs. This open frame construction also allows the horizontal thrusters to be mounted in the most efficient vectored arrangement providing far greater thrust in both forward and lateral directions than earlier axial and lateral thruster combinations.

A basic ROV system comprises the Vehicle, a Surface Control Unit a Hand Control Unit and a Power Supply Unit. The surface Control unit and PSU can be supplied free standing or as a containerised system. This Control Container can be Zone II rated or rated for safe area operations. It is air conditioned as standard.

Free swimming operations are possible with up to 450 metres of tether. For operations with umbilical lengths greater than 450 metres it is necessary to use a Seaeye Tether Management System (TMS). This can either be the economical Type 2 bale arm system providing an excursion range of 140 metres or the superior Type 5 TMS which is a winch and slip ring arangement. The Type 5 TMS with its variable garage opening height provides ROV excursions from the TMS of up to 240 metres.

The manufacturer offers a skid mounted 'A' frame and lifting winch with metres of armoured lift umbilical as a compact combined unit to launch and recover a TMS garaged Seaeye Tiger. Alternatively an articulated crane and winch unit can be offered mounted on a gravity base. These options can be offered rated for hazardous area Zone II operations or for 'safe area' operations and are known as a 'LARS' or Launch and Recovery System. Alternatively you may have your own crane available and may only require the lifting winch and armoured umbilical with an umbilical sheave and a lock-latch release mechanism and vehicle bullet for launch and recovery.

ROV NEWS FROM AROUND THE WORLD.

DEEPOCEAN PICKS NEW LEOPARD CONCEPT FOR MV DEEP HELDER

DeepOcean has opted for the new concept Leopard ROV from Saab Seaeye. Seen as the most powerful ROV of its size in the world, its combination of 11 thrusters, unrivalled payload, and a host of advanced technology features won over DeepOcean, which itself is an innovator in providing subsea services. "It's a pioneering design from Saab Seaeye - a company with a track record of innovation," says Rick Green, Regional Manager Netherlands at DeepOcean, "and will be a valuable addition to our fleet. "Environmentally we wanted an electric vehicle - yet one with work class performance. "For our application the Leopard gives us the equivalent capability of a much larger hydraulic work class vehicle - and its 11 thrusters means it can handle strong currents - and that's important to us." He points out that with eight horizontal thrusters and three vertical thrusters the Leopard can hold steady in strong cross-currents. Rick Green also likes the ROV's inventive new chassis concept. Its large open payload bay allows for ample tooling and survey sensors to be installed on sliding trays for rapid reconfiguration and easy maintenance. It means, he says, that a survey-grade INS system can now be easily integrated inside the vehicle.

The combination of new chassis design, iCON intelligent architecture with building-block capability, and exceptional power, means that more interchangeable equipment can be fitted than ever before in a vehicle of this size. With a one tonne through-frame lift capability and a four-point docking system for tooling skids, more demanding payloads can be added to the Leopard as needed. Yet despite its extra capabilities, the total Leopard package is designed for easy transport and rapid mobilisation - by staying within a minimal deck footprint combination of 20ft x 8ft single lift A-Frame & winch LARS, and a 20ft control cabin. Designed with the pilot in mind, the Leopard has many inventive features to make life easier for the operator in the field. The pilot will find that the iCON intelligent control system delivers better handling characteristics - including pitch and roll stabilisation for the best quality survey data - and offers stable flight even when large tools and sensors are deployed. The iCON architecture also gives clear and enhanced information whilst independently managing each device on the vehicle, including auto redundancy that will keep the ROV working even with multiple equipment damage. Through iCON the main electronics pod has been refined into an intelligent power distribution and data hub, with the brains of the system re-located into sensors and actuators around the vehicle. This provides greater information for the user and makes maintenance far simpler and quicker. Distributing intelligence around the vehicle avoids the need to partially dismantle the ROV to reach a central electronic heart and offers building-block simplicity for equipment changes, along with enhanced remote internet access for upgrades and support.

RECORD SWIM FOR HIBBARD WITH SABERTOOTH.

Hibbard Inshore has set the record for the longest flooded tunnel inspection against flow ever attempted. Success came from using the Saab Seaeye Sabertooth AUV/ROV hybrid, chosen as the only possible vehicle for the job. Used as a tethered ROV, which was extremely important to Hibbard for real time data feedback, vehicle control, and safety measures, the Sabertooth swam the eight kilometres of tunnel against a 0.3 metre-per-second flow whilst fitted with a range of surveying and filming systems. This achievement kept the vital water supply flowing to Rio Tinto's aluminium smelting plant in British Columbia during the inspection mission. Speed was essential as the flow was reduced during the mission and a 'very fast' inspection in an eight-hour timeframe was needed, says Dave Malak, Director of Hibbard Inshore. The Sabertooth was fitted with a combination of multi-beam systems and cameras to provide 3D profiling of the tunnel, along with a record of the tunnel wall status and HD video examination of areas of concern. For Rio Tinto the 40 year-old tunnel is a critical asset that needed a thorough examination to reveal areas of potential collapse for maintenance planning and to provide comparable data for trends in tunnel condition. Hibbard's success follows their record-breaking 24 kilometre tunnel inspection inside Australia's Snowy Mountain hydro scheme where they also used the Sabertooth in its tethered mode.

Sabertooth - record breaking design for long tunnel inspection

The Sabertooth concept combines the technologies of both AUV and ROV vehicles into a single unified resource to give operators the range and manoeuvrability of an AUV, yet with the tooling capability of a light-work ROV. Hibbard Onshore were first to spot the potential of the Sabertooth concept, recognising the advantages of a vehicle that has 360 degree manoeuvrability, a sleek hydro-dynamic design, efficient thrusters and accurate navigation - and an ability to cope with flowing water in a confined space. They also saw the benefit of battery technology that could operate the Sabertooth over extremely long distances under its own power so that only a thin fibre-optic cable need be used when necessary.

LEOPARD ROV.

The new Leopard is the most powerful compact work-class ROV in the market. With 11 thrusters, unrivalled payload, and a host of advanced technology features, the new Saab Seaeye Leopard is the most powerful ROV of its size in the world. Aimed at the compact work-class market, the Leopard can handle more tooling, cameras and survey equipment than any other ROV in its class. The minimal deck footprint of the Seaeye range is maintained with the combination of a 20 x 8ft single lift, A-Frame & winch LARS and a 20ft control cabin for easy transport and rapid mobilisation. Its pack of eight horizontal thrusters and three vertical thrusters gives the Leopard exceptional thrust, powering the vehicle forward at over four knots, and enabling it to hold steady in strong cross-currents. For the pilot, the vehicle's iCON intelligent control system gives clear and enhanced information whilst independently managing each device on the vehicle, including auto redundancy that will keep the ROV working even with multiple equipment damage. The pilot will also find that it delivers better handling characteristics - including pitch and roll stabilisation for the best quality survey data and to allow stable flight even with large tools and sensors deployed. Designed with the pilot in mind, the Leopard has other inventive features to make life easy for the operator in the field. For instance the networked design of the iCON control system has refined the main electronics pod into an intelligent power distribution and data hub, and re-located the brains of the system into sensors and actuators around the vehicle. This provides greater information for the user and makes maintenance far simpler and quicker. This innovation also avoids the need to partially dismantle the ROV to reach its electronic heart. And it offers building-block simplicity for equipment changes along with remote internet access for upgrades and support. The chassis has been designed with rapid reconfiguration and easy maintenance in mind. A large open payload bay within the vehicle allows for ample tooling and survey sensors to be installed rapidly on sliding trays. Its one tonne through-frame-lift capability and four point docking system for tooling skids allows more demanding payloads to be added. The combination of new chassis design, iCON building-block concept and exceptional power, means that more interchangeable equipment can be fitted than ever before in a vehicle of this size. Operators can therefore use the Leopard for a wide range of work tasks including drill support, pipeline survey, salvage and deep water IRM.

Remotely operated underwater vehicles (ROVs).

A remotely operated underwater vehicle, commonly referred to as an ROV, is a tethered underwater vehicle. They are common in deep water industries such as offshore hydrocarbon extraction. While the traditional abbreviation "ROV" stands for remotely operated vehicle, one must distinguish it from remote control vehicles operating on land or in the air. ROVs are unoccupied, highly maneuverable and operated by a crew aboard a vessel. They are linked to the ship by either a neutrally buoyant tether or often when working in rough conditions or in deeper water a load carrying umbilical cable is used along with a tether management system (TMS). The TMS is either a garage like device which contains the ROV during lowering through the splash zone, or on larger work class ROV's a separate assembly which sits on top of the ROV. The purpose of the TMS is to lengthen and shorten the tether so the effect of cable drag where there are underwater currents is minimized. The umbilical cable is an armored cable that contains a group of electrical conductors and fiber optics that carry electrical power, video and data signals back and forth between the operator and the TMS. Where used, the TMS then relays the signals and power for the ROV down the tether cable. Once at the ROV, the electrical power is split and distributed between different components of the ROV. However, in high power applications, most of the electrical power is used to drive a high powered electrical motor which drives a hydraulicpump. The hydraulic pump is then used for propulsion and to power equipment such as torque tools and manipulator arms where electrical motors would be too difficult to implement sub sea. Most ROV's are equipped with at least a video camera and lights. Additional equipment is commonly added to expand the vehicle’s capabilities. These may include sonars, magnetometers, a still camera, a manipulator or cutting arm, water samplers, and instruments that measure water clarity, water temperature, water density, sound velocity, light penetration and temperature.

History

In the s and '80s the Royal Navy used "Cutlet", a remotely operated submersible, to recover practice torpedoes and mines. RCA (Noise) maintained the "Cutlet 02" System based at BUTEC ranges, whilst the "03" system was based at the submarine base on the Clyde and was operated and maintained by RN personnel. The US Navy funded most of the early ROV technology development in the s into what was then named a "Cable-Controlled Underwater Recovery Vehicle" (CURV). This created the capability to perform deep-sea rescue operation and recover objects from the ocean floor, such as a nuclear bomb lost in the Mediterranean Sea after the Palomares B-52 crash. Building on this technology base; the offshore oil & gas industry created the work class ROVs to assist in the development of offshore oil fields. More than a decade after they were first introduced, ROVs became essential in the s when much of the new offshore development exceeded the reach of human divers. During the mid-s the marine ROV industry suffered from serious stagnation in technological development caused in part by a drop in the price of oil and a global economic recession. Since then, technological development in the ROV industry has accelerated and today ROVs perform numerous tasks in many fields. Their tasks range from simple inspection of subsea structures, pipeline and platforms to connecting pipelines and placing underwater manifolds. They are used extensively both in the initial construction of a sub-sea development and the subsequent repair and maintenance. Submersible ROVs have been used to locate many historic shipwrecks, including that of the RMS Titanic, the Bismarck, USS Yorktown, and SS Central America. In some cases, such as the SS Central America, ROVs have been used to recover material from the sea floor and bring it to the surface. While the oil & gas industry uses the majority of ROVs; other applications include science, military and salvage. Science usage is discussed below, the military uses ROV for tasks such as mine clearing and inspection.

Construction

Work Class ROV's are built with a large flotation pack on top of an aluminium chassis to provide the necessary buoyancy to perform a variety of tasks. Syntactic foam is often used for the flotation material. A tooling skid may be fitted at the bottom of the system to accommodate a variety of sensors or tooling packages. By placing the light components on the top and the heavy components on the bottom, the overall system has a large separation between the center of buoyancy and the center of gravity: this provides stability and the stiffness to do work underwater. Electrical components can be in oil-filled water tight compartments or one atmosphere compartments to protect them from corrosion in seawater and being damaged by the extreme forces exerted on the ROV while working deep. Thrusters are usually in a vectored configuration to provide the most precise control as possible. The ROV will be fitted with cameras, lights and manipulators to perform basic work. Additional sensors and tools can be fitted as needed for specific tasks. The majority of the work class ROV's are built as described above; however, this is not the only style in ROV building method . Specifically, the smaller ROV's can have very different designs, each geared towards its own task.

Military ROV

In October the U.S. Navy began to replace its manned rescue systems, based on the Mystic DSRV and support craft, with a modular system, the SRDRS based on a tethered, unmanned ROV called a pressurized rescue module (PRM). This followed years of tests and exercises with submarines from the fleets of several nations.The US Navy also uses an ROV called AN/SLQ-48 Mine Neutralisation Vehicle (MNV) for mine warfare. It can go yards away from the ship, and can reach feet deep. The mission packages available for the MNV are known as MP1, MP2, and MP3.

The MP1 is a cable cutter to surface the moored mine for recovery exploitation or EOD detonation.
The MP2 is a bomblet of 75 lb PBXN-103 high explosive for neutralising bottom/ground mines.
The MP3 is a moored mine cable gripper and a float with the MP2 bomblet combination to neutralise moored mines underwater.

The charges are detonated by acoustic signal from the ship.

The AN/BLQ-11 autonomous Unmanned Undersea Vehicle (UUV) is designed for covert mine countermeasure capability and can be launched from certain submarines.The ROVs are only on Avenger class mine countermeasures ships. There are currently 13 ships, operating mostly off the coast of Japan and California, and there are always four US minesweepers in the Persian Gulf: USS Ardent (MCM-12), USS Dextrous (MCM-13), USS Scout (MCM-8) and USS Gladiator (MCM-11).During August 19, , a Boeing-made robotic submarine dubbed Echo Ranger was being tested for possible use by the U.S. military to stalk enemy waters, patrol local harbors for national security threats and scour ocean floors to detect environmental hazards. As their capabilities grow smaller ROVs are also increasingly being adopted by navies, coast guards, and port authorities around the globe, including the U.S. Coast Guard and U.S. Navy, Royal Netherlands Navy, the Norwegian Navy, the Royal Navy and the Saudi Border Guard. They have also been widely adopted by police departments and search and recovery teams. Useful for a variety of underwater inspection tasks such as explosive ordnance disposal (EOD), meteorology, port security, mine countermeasures (MCM), and maritime ISR (Intelligence, Surveillance, Reconnaissance).

Science ROVs

ROVs are also used extensively by the science community to study the ocean. A number of deep sea animals and plants have been discovered or studied in their natural environment through the use of ROVs: examples include the jellyfishBumpy and the eel-like halosaurs. In the USA, cutting edge work is done at several public and private oceanographic institutions, including the Monterey Bay Aquarium Research Institute (MBARI), the Woods Hole Oceanographic Institution (WHOI) (with Nereus), and the University of Rhode Island / Institute for Exploration (URI/IFE).[2][3] The picture to the right shows the behavior and microdistribution of krill under the ice of Antarctica.Science ROVs take many shapes and sizes. Since good video footage is a core component of most deep-sea scientific research, research ROVs tend to be outfitted with high-output lighting systems and broadcast quality cameras.[4] Depending on the research being conducted, a science ROV will be equipped with various sampling devices and sensors. Many of these devices are one-of-a-kind, state-of-the-art experimental components that have been configured to work in the extreme environment of the deep ocean. Science ROVs also incorporate a good deal of technology that has been developed for the commercial ROV sector, such as hydraulic manipulators and highly accurate subsea navigation systems.While there are many interesting and unique science ROVs, there are a few larger high-end systems that are worth taking a look at. MBARI's Tiburon vehicle cost over $6 million US dollars to develop and is used primarily for midwater and hydrothermal research on the West Coast of the US.[5] WHOI's Jason system has made many significant contributions to deep-sea oceanographic research and continues to work all over the globe. URI/IFE's Hercules ROV is one of the first science ROVs to fully incorporate a hydraulic propulsion system and is uniquely outfitted to survey and excavate ancient and modern shipwrecks. The Canadian Scientific Submersible Facility ROPOS system is continually used by several leading ocean sciences institutions and universities for challenging tasks such as deep-sea vents recovery and exploration to the maintenance and deployment of ocean observatories.

Scientific Sea Drones Are Becoming the Eyes of the Navy.

From hunting and hiding submarines to planning SEAL missions, a fleet of 65 aquatic, submersible drones is already giving the U.S. Navy a tactical advantage.

Last fall Rutgers University ocean researcher Oscar Schofield headed a collaborative experiment called Gliderpalooza, which coordinated 15 aquatic, submersible research drones to sample the deep waters off the coastal Atlantic. About 5 feet long and shaped like tomahawk missiles, the gliders beam home their data every time they surface. The propellerless drones, jam-packed with scientific instruments, swim by changing their buoyancy—taking on and expelling a soda can's worth of water to sink and float. And they navigate under the waves by themselves. "The gliders are autonomous, so you just throw them in the water and off they go," Schofield says, though they can also take directions from operators when they surface. With this robotic flotilla—part of the new wave of ocean-going drones—Schofield and his colleagues could gather a detailed picture of the ocean's temperature, currents, wildlife, and water quality at depths up to 650 feet. But even as ocean researchers use these gliders to track fish and help predict storms, the drones have attracted another admirer—the U.S. Navy. "Right now the Navy is at the forefront of this technology," Schofield says, "and the Office of Naval Research really funded and developed these gliders in the first place." The Navy currently owns 65 of the same kind of gliders Schofield operates, with plans to expand to 150 by . But the Navy's interest isn't exactly in science. The fleet of gliders is helping the Navy gain a tactical advantage in the ocean's future war zones. Operational Planning. "As the Navy plans for operations, they have to look into the future," says Frank Bub, the lead ocean modeler at the Naval Oceanographic Office. In other words: As the Navy maps out anything from a SEAL team silently breaching onto shore to a subsurface naval exercise, it must predict how the movement of the seas will affect its plans. "The Navy relies on ocean models not just to forecast future conditions but to fill in the gaps where data may never have been collected," Bub says. This is where the gliders come in. By sending a scientific drone through or near an area of interest, the "gliders provide us real-time ocean data, and that has two major applications," Bub says. The Navy can use that data not only to check the accuracy of its models, but to adjust or correct them. "If the Navy SEALs have a mission and they're going ashore, they definitely want to know what the ocean conditions are from when they leave their mother ship to when they land on the beach," Bub says. Gliders could provide temperature data so the SEALs wear the right gear, or gliders could give the most accurate description of currents so the SEALs swim in the right direction as quickly and quietly as possible. Where the gliders can have the biggest impact are the places where the Navy can't or isn't allowed to go. While he's not at liberty to list them all, Bub points to places where the Navy currently has significant interest: "The Navy is in the western Pacific, the northern Indian Ocean, and the Navy spends time in the Mediterranean," he says. It's in these places (perhaps even around the increasingly tense East China Sea) that gliders could slip in silently to gather intelligence. "The gliders are clandestine," Bub says. "They spend very little time on the surface, they're not generally detectable, and although they communicate through the Iridium satellite system, they've been encrypted." And Schofield says this type of clandestine mission could be done from far away. Even though the gliders swim at less than a mile per hour, their propellerless propulsion and battery packs allow them to stay at sea for up to a year. "And you can launch a glider pretty far away from a region of interest. I could deploy one a hundred miles away from where I have it fly in," Schofield says.

Hunting and Hiding Submarines. Much of the time submarines operate in the dark—they're often deployed to places with limited oceanographic data. Schofield uses temperature as an example. "Satellites observe sea surface temperature by using infrared light," he says, "but infrared light penetrates only centimeters into the water, so you can't really extract any information from very deep in the ocean." Without satellites, ocean modelers rely only on a few thousand global research buoys as well as ships and research stations, which combine to provide an uneven and low-resolution picture. Bub says it's crucial for a sub commander to understand both the temperature and salinity of deep waters. That's because the key to avoiding detection is to understand not only how much sound you're producing but where and how far it's traveling, and temperature and salinity play important roles in how sound propagates underwater. "Sound in warm water goes faster than sound in cold water, and just like light, it will refract and bend," with changes in the salinity, depth, and temperature of the water, Bub says. "So for submarine warfare, the key is to take these qualities and convert them into sound speed. Then we can run acoustic models and find out how the sound propagates through the ocean." Here, too, undersea gliders—which take snapshots of the deep ocean several times per second—are ideally suited for the job. Although the current Navy drones can reach a depth of only feet, the Navy already has plans for a newer version that could dive to more than 1 mile below sea level. By mapping the deep seas, the Navy thinks it can find places that are best for hiding subs. "And on the other hand, our destroyers and other antisubmarine warfare ships want to know where other submarines are," Bub says. By taking advantage of our glider-aided acoustic models, "we can actively put sound in the water," with things such as active sonar and sonobuoys, "which travels on paths that are determined by our ocean models," he says.

Submerged Submarine Launches Aircraft.

An all-electric, fuel cell-powered, unmanned aerial system (UAS) aircraft has been successfully launched from the submerged 'USS Providence' (SSN 719) & flew a several hour mission demonstrating live video capabilities streamed back to the submarine, surface support vessels and Norfolk base before landing at the Naval Sea Systems Command Atlantic Undersea Test and Evaluation Center (AUTEC), Andros, Bahamas. From concept to fleet demonstration, the Navy says this idea took less than six years to produce in a collaboration between the U.S. Naval Research Laboratory (NRL) with funding from SwampWorks at the Office of Naval Research (ONR) and the Department of Defense Rapid Reaction Technology Office (DoD/RRTO).The successful submerged launch of a remotely deployed UAS offers a pathway to providing mission critical intelligence, surveillance and reconnaissance (ISR) capabilities to the U.S. Navy's submarine force. The NRL developed aircraft XFC UAS - experimental Fuel Cell Unmanned Aerial System - was fired from the submarine's torpedo tube using a 'Sea Robin' launch vehicle system. The Sea Robin launch system was designed to fit within an empty Tomahawk launch canister (TLC) used for launching Tomahawk cruise missiles already familiar to submarine sailors. Once deployed from the TLC, the Sea Robin launch vehicle with integrated XFC rose to the ocean surface where it appeared as a spar buoy. Upon command of Providence Commanding Officer, the XFC then vertically launched from Sea Robin. The XFC aircraft is a fully autonomous, all electric fuel cell powered folding wing UAS with an endurance of greater than six hours. The non-hybridized power plant supports the propulsion system and payload for a flight endurance that enables relatively low cost, low altitude, ISR missions. The XFC UAS uses an electrically assisted take off system which lifts the plane vertically out of its container and therefore, enables a very small footprint launch such as from a pickup truck or small surface vessel.

CUTTING THE COST OF HUNTING SHIPWRECKS.

Nearly 100 years after the three-masted schooner, the Hattie Wells, sank in Lake Michigan during heavy weather, it has been filmed by the most advanced ROV of its kind in the world. A key element of the mission undertaken by a team of marine archaeologists has been to prove the value of using an ROV to document shipwrecks in America's Great Lakes, says Dr Mark Gleason, chief marine scientist and director of education at Great Lakes Naval Memorial and Museum (GLNMM). By turning to specialist ROV operator, Seaview Systems, they were able to cut the cost usually associated with launching an ROV from a large support vessel by using the compact but highly sophisticated deep-rated Saab Seaeye Falcon DR ROV. Matthew Cook of Seaview Systems explains that marine archaeology requires the collection of high quality video, still images and environmental and position data of a shipwreck in order to capture the full historical significance of the site. He sees an ROV as representing a very efficient means of collecting this information in a wide range of water depths. 'One of the larger expenses in a research project,' says Matthew Cook, 'is the support vessel from which ROV operations are conducted. Since we have been leveraging the benefits of the compact fiber optic Falcon DR which can dive to m from relatively inexpensive vessels of opportunity, in order to explore a range of historic shipwrecks, corals and other benthic habitats.

Falcon launched into Lake Michigan.

'The fiber optic Seaeye Falcon DR represents an ideal balance of capability and ease of mobilization in a small, powerful and stable package. By deploying from a relatively inexpensive vessel of opportunity, project budget is conserved allowing for a longer, more detailed campaign. Running a wide bandwidth fiber optic system means the vehicle is able to support a host of sensors and cameras normally only found on larger vehicles.' The Hattie Wells project that has included archival research, sidescan survey and ROV dive operations, has brought together representatives from government, private business and educational non-profits. Built in the Hattie Wells was originally a 135 ft three-masted schooner, later lengthened by 30 ft and the rigging removed. Over the years she courted disaster on a number of occasions including collision, grounding and a lightning strike. After grounding in she was given up for lost but was later salvaged as a wreck and towed back to Detroit for refit. Once again afloat, she continued in service, later as a barge. In November , whilst hauling timber, she hit heavy weather and took in water. Shifting cargo smashed the pilot house containing the donkey engine that powered the bilge pumps. With the only means of removing water gone, the vessel was doomed to sink and so the towing tug cut the hawser and rescued all five hands on board. The Falcon DR has a world-wide following with over 220 in use offshore, inshore and down tunnels. Users are attracted by the Falcon's reputation for power, reliability and unequalled stability in strong cross-currents - particularly in a vehicle small enough to be manhandled into the water. Rapid role-change during operations is a key feature where intelligent electronics offer a 'plug and go' simplicity that allows up to 128 devices to be added and changed easily, such as extra cameras, lights, tracking system, manipulator and sonar, plus the option of adding special tooling on a removable skid. Its unrivalled finger-tip manoeuvrability comes from five brushless DC thrusters with velocity feedback for precise and rapid control in all directions and an ability to hold steady in strong cross currents. The deep rated Falcon has built-in fibre optics for high volume data transmission over its long umbilical, and the ability to use broadcast quality video cameras. It also has tilting variable intensity lights linked to its camera tilt mechanism for superior illumination when filming above or below the vehicle. Dr Gleason of GLNMM concludes, 'I think it is safe to say each organisation had different objectives. Ours was to demonstrate, through a real project, the usefulness of this type of ROV in documenting shipwrecks in the Great Lakes. Plus we wanted to work in partnership with Seaview, NOAA and MSRA/NUMA to explore a new shipwreck and hopefully be able to partner on larger projects in the future.

THE SAAB SEAEYE COUGAR HUNTS IN CASPIAN JUNGLE.

With the Caspian seabed a hazardous jungle of un-recorded old pipes and cables from the Soviet era, a Cougar XT ROV from Saab Seaeye is to become a vital investigative tool now that new pipelines are being laid. After a favourable experience operating the vehicle elsewhere, highly skilled engineers of the State Oil Company of Azerbaijan, SOCAR, decided to deploy the Cougar XT in the Caspian Sea for their underwater applications. The ROV will be used for diving and pipeline inspection of the SOCAR current projects, and for future seabed inspection as new pipes are laid. In addition to pipeline inspection and seabed survey, it will be used for a variety of tasks including the inspection and survey of vessels and platform legs. SOCAR has taken a high-spec version of the m rated Cougar XT with an upgraded video package including two Kongsberg high-definition mono low-light cameras, two Kongsberg colour zoom cameras, pan and tilt platform and LED lighting. The ROV will be launched from a Saab Seaeye stainless steel tether management system fitted with a camera and upgraded MUXs. Deploying the Cougar will be a crane style launch and recovery system, supplied with a bullet/swivel assembly and lock latch assembly, together with an A60 zone ll rated ROV control cabin.

POWER TO THE SEAEYE ROV OPERATOR.

A more powerful ROV than any other of its class on the market has been launched by top manufacturer, Saab Seaeye. The Panther XT Plus, rated for operation to a depth of m, is the latest addition to the successful Panther range - and with two systems already sold for delivery in the first quarter of this latest version is generating considerable interest in the ROV market. The new advanced ROV gives operators about double the horizontal thruster power compared with the Panther XT, which makes it the most powerful ROV in its class with over 50% more thrust than its nearest competitor. Its power to weight ratio is also over twice its nearest competitor providing exceptional response and precise control. Packed with ten powerful thrusters, not only can it swim over 30% faster than anything else of its type, but it can hold steady in strong cross currents, making it an ideal vehicle for survey work. Having ten thrusters in hand also brings peace of mind to operators working to a tight deadline or in difficult conditions by offering a reassuringly high degree of redundancy. In addition to unrivalled thrust performance, the front end of the Panther XT Plus has been re-designed to accommodate industry standard seven function position feedback manipulators providing the operator with heavy-duty power and precise control allowing faster completion of complex manipulator tasks. To accommodate the larger and heavier manipulator arms and provide additional capacity to fit further tools and sensors the vehicle payload has been significantly increased over the standard Panther XT. For the ROV operator, another significant advantage of increased power found in the new light-work ROV, is an ability to carry a greater range of tooling options for a wider range of tasks, including work, observation and survey, all in a small footprint. This need for less deck space, around a quarter of an equivalent hydraulic vehicle, together with fewer crew and lower vehicle cost, gives an overall lower cost of ownership that lies behind the success of the long established Panther range, a design concept that can match an hydraulic equivalent in most work tasks including drill support, IRM, survey and some construction tasks.

Robotic Submarines Removing Oil Leak.

Robotic submarines removed the cap that had been placed on top of the leak in early June to collect the oil and send it to surface ships for collection or burning. BP aims to put a new, tighter cap in place and said that, as of Saturday night, the work was going according to plan. If tests show it can withstand the pressure of the oil and is working, the Gulf region could get its most significant piece of good news since the April 20 explosion on the BP-leased Deepwater Horizon rig, which killed 11 workers. BP began trying Saturday afternoon to remove the bolted top flange that only partially completed the seal with the old cap. Video images showed robotic arms working to unscrew its bolts. Wells said that could last into Monday depending on whether the flange can be pulled off from above, as BP hopes. If not, a specially designed tool will be used to pry apart the top and bottom flanges. Once the top flange is removed, BP has to bind together two sections of drill pipe that are in the gushing well head. Then a 12-foot-long piece of equipment called a flange transition spool will be lowered and bolted over it. The second piece of pipe inside the well head came as something of a surprise, and raises the possibility that one of the sections of pipe became jammed in the Deepwater Horizon's blowout preventer, though which the well pipes run. The failure of the blowout preventer, a massive piece of equipment designed to stop the unchecked flow of oil, is partly to blame for the size of the spill. Ultimately, BP wants to have four vessels collecting oil within two or three weeks of the new cap's installation. If the new cap doesn't work, BP is ready to place a backup similar the old one on top of the leak. The government estimates 1.5 million to 2.5 million gallons of oil a day are spewing from the well, and the previous cap collected about 1 million gallons of that. With the new cap and the new containment vessel, the system will be capable of capturing 2.5 million to 3.4 million gallons - essentially all the leaking oil, officials said. The plan, which was accelerated to take advantage of a window of good weather lasting seven to 10 days, didn't inspire confidence in the residents of the oil-slicked coast. Robotic submarines working a mile underwater removed a leaking cap from the gushing Gulf oil well Saturday, starting a painful trade-off: Millions more gallons of crude will flow freely into the sea for several days until a new seal can be mounted to capture all of it. There's no guarantee for such a delicate operation almost a mile below the water's surface, officials said, and the permanent fix of plugging the well from the bottom remains slated for mid-August. How It Would Work. The latest effort to cap and contain the Gulf oil spill is a multistep process.

Here's how it would work:

1. The existing containment cap will be removed - perhaps in a matter of minutes.

2. Robot submarines will then remove a stub of pipe that's bolted to the top of the blowout preventer. That could be tricky, involving the removal of six large bolts. Once the stub is removed, that will expose a flat plate, or flange.

3. Two pipes that are sticking up inside the blowout preventer will be then strapped together.

4. BP will then install a cylindrical device over the protruding pipes that will be bolted down onto the flange.

5. BP will then install a manifold, or valve system, on top of that cylindrical device.

6. Once that valve system is in place, BP will need to connect four pipes or houses to oil processing ships at the surface. That should be enough to capture 60,000 to 80,000 barrels of oil per day, which should be enough to capture all the oil from the runaway well. Federal officials estimate that the well is spewing between 35,000 and 60,000 barrels of oil per day.

Robotic Submarines Navigate Underwater Course Autonomously.

Teams from nine universities gathered at NATO's Undersea Research Center to pit their robotic submarines against each other. Hanwha, a Korean conglomerate involved in the chemicals, explosives and defense sectors, is set to advance into the commercial market for unmanned submarines after securing the government’s commitment for technology transfer. According to the Ministry of Land, Transport and Maritime Affairs, Hanwha has agreed to purchase core technologies involving the designing and manufacturing of unmanned submarines that have been developed by the state-run Korea Ocean Research and Development Institute (KORDI) since . The global market for unmanned submarines is currently divided between companies from the United States, Canada, Britain, Norway and Russia, and the front-runners have been serious about preventing potential rivals from accessing their technologies. Korea, eager to get a slice of the market, was willing to start from scratch. About 3.5 billion won ($2.9 million) in taxpayers’ money was spent on KORDI’s research, ministry officials said, and Hanwha will be paying 7.5 billion won for the results. Robotic, remote-controlled submarines, which are capable of gliding through the ocean and penetrating inaccessible spots, are garnering increasing attention from governments and companies for their distinctive edge in exploration. The current model designed by KORDI is capable of patrolling shallow waters less than 500 meters deep, but the government is financing a separate project to develop unmanned submarines that could reach depths of 6,000 meters. Hanwha is expecting healthy demand for its future unmanned submarines, including potential interest from the military. The unmanned submarines could be used for monitoring territorial waters, exploring for resources or supporting oceanographic studies. They could also be used to investigate pollution in rivers, said a Hanwha spokesman. These machines could also provide a more effective way to patrol sea boarders and detect and destroy mines.

UNIVERSITY OF MICHIGAN ORDERS IVER2- AUV.

OceanServer has received a fourth contract from the University of Michigan for an Iver2 EP42 equipped with Side Scan Sonar, 10 beam DVL and ADCP. Early this year, OceanServer delivered the University’s third vehicle for service in the Great Lakes. The new vehicle will be used as part of the Great Lakes Observing System Tributary Monitoring project with funding from the Great Lakes Restoration Initiative. The project looks at monitoring five separate Areas of Concern across all five Great Lakes, using different monitoring methods. The University of Michigan’s part of the project will be using the Iver2 AUV for surveying Saginaw Bay, an Area of Concern in Lake Huron. Researchers will use a Bottom Classification Software with the sonar to support an on-going study of Cladophora growth that leads to unsightly and foul smelling muck on the beaches. The new Iver vehicle will also be used for mapping fish habitats and reefs. All Iver2 AUV models come standard with OceanServer’s VectorMap Mission Planning and Data Presentation tool, which provides geo-registered data files that can be easily exported to other software analysis tools. This unique AUV design has enabled OceanServer to carve out a very strong position in the research space for Autonomous Underwater Vehicles, sensors and behavioral studies. The VectorMap program can input NOAA ENCs or any geo-referenced charts, maps or photo images, allowing the operator to intuitively develop AUV missions using simple point-and-click navigation. The base vehicle, with a starting price at just over $50,000 USD, gives university, government and commercial users an affordable base-platform for sensor development or survey applications in water quality, sub-surface security and general research.

WORLD’S SMALLEST AND SMARTEST SURVEY SYSTEM CUTS COSTS.

An inshore cable survey system that cleverly senses the presence of cables, and uses a smaller ROV than usual, is set to significantly cut the cost of survey work in the burgeoning marine energy industry. Costs can be cut from £500,000 for a conventional system to just £150,000 for this innovative new solution. Cleverly, Submagnetix, a division of Innovatum, has integrated their system with the compact Saab Seaeye Falcon ROV to create a small and rapidly mobilised package that can be deployed from a small vessel, ready to survey all types of inshore and coastal submarine cables and pipelines. Called SMARTRAK 9, it is the only system in the world that can sense cables carrying either AC or DC current; and cables carrying no current or signal at all. It can also sense steel pipelines. The Seaeye Falcon ROV is fitted out with a Tritech Super SeaKing profiler system to provide high quality cross-sectional profile data of the seabed; to give underwater ROV positioning a Tritech Micron-Nav USBL navigation transducer along with pitch and roll sensing; an accurate flux gate compass; a high accuracy altimeter and a pressure sensor for depth. For survey work, the Seaeye Falcon has the advantage of a low electrical and acoustic noise signature allowing for optimum survey sensor data. It also has the power and manoeuvrability to give unrivalled stability in strong cross currents. And with over 200 in use around the globe, the Falcon has the reliability of a trusted design that is packed with technological innovations including intelligent ‘plug-and-go’ electronics that enable different tooling to be added and changed as needed.

Robotic submarines of the future.

World’s oceans has no shortage of resources, on the contrary, there are untapped resources or resources for which is seeking means of exploitation. Most of untapped resources are found at deep in the sea, a depth of over 4,000 meters (2.5 miles). Such a high deep involves important technological resources for exploitation and also high increasing costs. The appetite for world’s resources are increasing, one common barrier found in exploitation of deep sea is the currently used technologies. A submarine controlled from a ship is always in contact with the user through cables. Is not yet invented an alternative technologies to substitute the cables used to control the submarines. Radio waves cannot propagate in the water, are the same as a train arrived at the end of the line from where it can go on. The optimal solution is not the use of thousands of meters of cable to control the submarine. In addition it is almost impossible to make an operation to thousands of meters deep with such a long cable. Exploitation the resources of the oceans in future belongs to robots. Used for many years for the most difficult and dangerous tasks, the robots represent the ideal solution for exploitation of resources found in oceans or sea. Since from the AUV concept of the University of Washington were made the first steps in developing autonomous underwater vehicles(AUV). Autonomous vehicles must comply with certain principles without which there can be chances of exploitation. These must be equipped with artificial intelligence to avoid obstacles, change course, and make other decisions in response to its environment.

Odyssey IV

Odyssey IV is the latest robot submarine built in the halls of science of MIT. Fortunately is not just a project on a piece of paper, is a completed and functional project. If in introduction I wrote about depth of up to meters, Odyssey IV perhaps more than. In a demonstration made by builders, the robot reached the impressive depth of meters in depth of the ocean. Diving speed is 1,4 m/s.
Odyssey meets all requirements of an autonomous robot. It can pick up samples and other cargo from the deep sea and bring them back to the surface for inspection and analysis. Retains its position in water with an accuracy of a few centimeters, as well as a predator that comes to hunting and wait for prey. Any exist on earth and is independent needs intelligence. The devices become smart using artificial intelligence. This is so well put into practice by researchers from MIT for Odyssey that it acts as an exemplary employee who makes his task on time and meet their program. The submarine has only 2 meter long. The design is inspired by nature, a design able to lead the device at the greatest depth in the shortest time. Not only its shapes do all the work to dive into the deep ocean. The submarine could not move up and down without the 4 four thrusters: one in the bow, one in the stern, and two mounted on arms that protrude from the sides of the vehicle and can be rotated about its lateral axis. The energy of the robot is provided by 648 lithium-ion cells that can power all systems a full day or more. The same batteries provide power for cameras mounted on submarine, images are received at the surface with a delay of several seconds. Images are transmitted by sound. Both the image quality and the time elapsed between sending and receiving images will be improved in future by using new technologies for data compression. The next steps in the development of this undersea platform is to increase the size and improving how to solve tasks independently.

UJI

Also in a university was born UJI, a robot submarine who can rescue black boxes or used for oil companies. UJI ,or made in UJI, is an autonomous robot which requires no human hand, is small and lightweight – weighs only 200 kilograms. If the robot from MIT resist in water at least one day, UJI robot has low performance. We can say that is an exemplary diver who can work only 8 hours in water. In all these hours of work the device can be loaded with up to 12 kg of material. The robot can be used in oil exploration in deep-sea rescue, treasure hunts and all sorts of objects in underwater archeology, clean ports, or take samples.

Unmanned Subs Making Waves In Undersea Warfare

Unmanned aircraft have been playing a major role in the wars in Iraq and Afghanistan for years. Now, the U.S. military is beginning to field unmanned submarines.

In a move that could dramatically cut the cost of undersea warfare, NATO is testing three Autonomous Undersea Vehicles, or AUVs, in the Mediterranean Sea this month as part of the alliance’s largest annual anti-submarine warfare exercise.

The AUVs, dubbed “gliders,” have much in common with their flying cousins, including wings, according to Michel Rixen, a scientist at the NATO Undersea Research Center in Italy.

“They are very similar vehicles although the dynamics are changed a little,” Rixen said. “What is peculiar to the AUVs are buoyancy controls.”

The battery-powered gliders, which are about 6 feet long and weigh up to 130 pounds, can be launched from shore or from a small rubber boat. They move through the sea at less than 2 mph, using a pump that inflates and deflates an internal bladder to change the vehicle’s buoyancy in the same way a scuba diver might inflate a buoyancy jacket, he said.

“The changes in buoyancy require much less energy than a propeller,” he said, allowing the vehicle to stay underwater longer than a propeller-driven AUV.

In , a glider of the same type being used in this month’s Proud Manta 11 NATO exercise completed a trans-Atlantic crossing that lasted 221 days.

The gliders will be at sea for three weeks during the exercise, traveling up to 300 miles collecting data on water salinity and temperature and relaying it to scientists on shore, Rixen said. The data is important because it allows sonar operators to calculate the speed of sound through the water – something that helps them detect enemy submarines, he said.

In the past, such data was collected by manned submarines or surface ships.

“We are demonstrating that military oceanography can be conducted from the office, piloting the gliders remotely instead of sending a big submarine (in the case of covert operations) to do a couple of temperature and salinity profiles in the ocean,” he said.

The cost of sending a research ship to collect such data runs at $25,000 a day or more, said engineer Richard Stoner of the research center.

The three gliders — which were manufactured by Teledyne Web of Falmouth, Mass. — participating in the exercise have been at sea collecting data since Jan. 24.

As Proud Manta kicks off in earnest on Friday with six submarines, 19 aircraft and eight surface ships from 10 nations participating, the gliders moved outside the exercise area east of Sicily, Rixen said.

“We want to be careful in this first contribution,” he said. “We don’t want to have a glider hitting a submarine or vice versa.”

The U.S. Navy has conducted similar exercises with gliders, said Tom Curtin, the research center’s chief scientist.

In fact, the Navy is gradually acquiring more than 100 gliders and fielding them to operational units through the Naval Oceanographic Office, he said.

Eventually AUVs are likely to be fielded with the same capabilities as large submarines, Rixen said. Weapons could also be added to the AUVs, something that has already happened with unmanned aircraft, he said. “These are some of the aspects that we are considering,” he said. But he warned: “If these toys end up in bad hands that could play against us. Someone could potentially put [weapons] on them. That is something we need to be careful about.”

WHOI Selects Hydroid to Provide AUVs for Ocean Observatories Initiative

The Woods Hole Oceanographic Institution (WHOI) awarded .Hydroid (Pocasset, Massachusetts) an approxmiately $1 million contract to provide AUVs and docking stations to support the Pioneer Array of the Ocean Observatories Initiative (OOI), WHOI announced last week.

WHOI, as well as the Consortium for Ocean Leadership (COL), selected the company on for initial development and design modification of AUV systems to meet OOI specifications. Subsequent phases of the contract will lead to the delivery of production AUVs that will be used to collect data as a part of the OOI Pioneer Array located off the New England coast, with each vehicle capable of making more than 50 missions per year in water depths up to 600 meters.

The Pioneer Array spans the continental shelf-break, where water depths drop quickly from about 100 meters to greater than 500 meters over a distance of about 40 kilometers. The shelf break is a region of energetic and important ocean variability, a boundary region between cool coastal waters and warmer offshore and Gulf Stream waters. Biological productivity and variability are strong, and a goal of the Pioneer Array is to understand the interplay of physical and biological processes across many scales, from hundreds of meters to hundreds of kilometers.

"AUVs are a critical tool to rapidly sample variability on dynamically relevant scales within the complex frontal system," said Al Plueddemann, a WHOI senior scientist and project scientist for the Pioneer Array. "This capability is key to improving our understanding of interactions between the continental shelf and slope."

Irish-Led Mission Uses ROVs to Film Marine Life Three Kilometers Down

Undiscovered life-forms that thrive without sunlight in temperatures approaching boiling point may soon come to light thanks to an Irish-led marine research mission aboard the national research vessel Celtic Explorer. In collaboration with scientists from the U.K.'s National Oceanography Centre, researchers from University College, Cork, embarked yesterday from Galway, Ireland, for the Mid-Atlantic Ridge. The voyage is being filmed for the National Geographic Channel for inclusion in an upcoming series about the ocean.

The mission, led by Dr. Andy Wheeler of University College, Cork, will be investigating life at 3,000 meters below the surface of the sea on the hydrothermal vent field using the ROV Holland 1. These vents, which spew mineral-rich seawater heated to boiling point by volcanic material in Earth's crust below, are home to a rich variety of marine life that thrives in complete darkness on bacteria fed by chemicals.

"This expedition offers us the first opportunity to investigate mineral deposits and vent animals in this unexplored and important part of the Mid-Atlantic Ridge," said Dr. Bramley Murton of the National Oceanography Centre, Southampton, who first discovered the location of the vents on an expedition aboard the U.K. research vessel RRS James Cook in , and who is now leading the mineralization study on the expedition.

"Nothing is known about the hydrothermal vents, their mineral deposits or the life they support on the Mid-Atlantic Ridge between the islands of the Azores to the south and Iceland to the north. Because this part of the ridge is trapped between these islands, vent animals may have evolved in isolation and be quite unique from elsewhere," he said.

The expedition will catalogue and characterize the species found at the vents and investigate the rich deposits of deepwater corals on the Porcupine Bank's "Moira Mound," which has already been designated as a special area of conservation.

Teledyne to Manufacture LBS-Glider UUVs for Navy.

Teledyne Brown Engineering, Inc. (Huntsville, Alabama) received approval from the U.S. Navy to move into the full-rate production (FRP) phase on the littoral battlespace sensing-glider (LBS-G) program, parent company Teledyne Technologies Inc. announced July 11.

Valued at up to $53.1 million, the contract could provide the Navy with 150 marine gliders from the company if all options are exercised. Teledyne Brown will manufacture 35 gliders under the contract's first FRP option.

The Navy plans to use the fleet of deep and shallowwater gliders to acquire critical oceanographic data to improve positioning of fleets during naval maneuvers. The Teledyne Webb Research (East Falmouth, Massachusetts) Slocum Glider, a torpedo-shaped, two-meter-long UUV that uses changes in buoyancy as well as its wings and tail-fin steering to move through the water, is the cornerstone of the LBS-G program.

In its the contract with the Space and Naval Warfare Systems Command, Teledyne Brown recently delivered 15 low-rate initial production gliders to the Navy's Program Executive Office for C4I. The LBS-G gliders were developed and are manufactured by Teledyne Webb Research.

ROV market and technology trends.

Global ROV vehicle sales in totaled approximately $850 million. In , oil and gas purchased approximately 50% of ROVs, while ROV sales for defense & security and scientific research equaled 25% for each sector. Market drivers for ROVs are offshore drilling, the security environment, and the need for ocean data. The prospect for offshore drilling varies by location, yet offshore exploration in Brazil, Nigeria, Indonesia, and the Gulf of Mexico are expected to be strong. In the security market, ROVs are routinely used for forward observation, reconnaissance, and mine counter-measures by the military. ROVs will increasingly be adopted by organizations charged with ocean rescue and port security seeking effective tools for scanning and observation, including hull inspection. The need for data on the oceans is driven by the need for creating detailed maps for navigation and minerals extraction, particularly in the Arctic. The three market dynamics in the ROV market of particular note are 1) the growing market for mini and small ROVs driven, primarily, by their reduced cost and increased functionality; 2) the increasing number of sensors and robotics capable of being placed on vehicles; and 3) the reduction in cost of the platform relative to the cost of the instruments. The relative cost of instruments and platform is important to note because it indicates the maturation of the ROV technology. ROVs, although they remain highly sophisticated technology packages, have become adopted widely enough to expect continued cost reductions, or performance enhancements at the same cost. Four technology trends in ROVs can be identified. The ROV industry is keenly aware of the need to simplify the interface between the ROV operator and the vehicle. Most ROVs in use have multiple screens for monitoring the ROV vehicle status (health), feeds from onboard cameras and video, robotic arm manipulation, and receiving feedback from data collection instruments. The trend is to simplify the interface by having information provided on one screen. The integration of multiple systems requires the development of software. ROV and instrument manufacturers are working to improve the integration of systems developed independently. This after-market integration between the platform and instrumentation is sub-optimal. In the future, functional integration will be incorporated into the design of ROVs and onboard systems. The availability of relatively inexpensive High Definition (HD) camera and video has increased the demand for efficient data transmission from the ROV to the operator station. High definition allows better inspection of the underwater site due to improved quality of the image, better control of the vehicle, and allows for easy switching between video formats found in different parts of the world. The consequence is that the copper video transmission system used in most tethers must be replaced with fiber optic cable to accommodate the greater bandwidth required to transmit HD signals. Advances in fiber optic technology allow ROVs to communicate with the surface using millimeter-thin cables, allowing smaller diameters in the tether and reduced drag. The size of the average ROV is decreasing due to technological developments in instrumentation. Smaller ROVs are preferred to large ROVs, keeping everything else constant, because of better maneuverability and lower deployment costs. Small ROVs deployed by one or two-man crews are less expensive to operate than vehicles deployed with large landing and recovery systems (LARS) requiring several operators. Maintenance costs are also significant drivers for reducing the size of ROVs, particularly in the scientific research market. In the past, large vehicles were needed to house the instruments needed to accomplish the dive mission; however, as a result of the reduced size of onboard instruments, cameras and robotic arms (often with improved performance) the size of the required vehicle has been reduced. The exception to this trend is in missions requiring the completion of heavy intervention tasks, as in offshore construction, or in missions where payload capacity is critical. Another driver of reduced weight is the result of technology improvements allowing greater propulsion power through a given diameter of wire. This has allowed for reduced weight in the entire ROV deployment system, including lighter landing and recovery systems. Improvements in compact buoyancy have also reduced the weight and size requirements for ROVs. Hybrid ROVs (HROVs) are an interesting trend in the ROV market. Hybrid ROVs have tether-optional configurations in which the vehicle can conduct programmed missions free from the tether. The benefit of hybrid systems is increased maneuverability in locations where tethers would entangle or limit the ability to navigate around obstacles. Woods Hole’s Nerus and Saab’s Seaeye are examples of workclass HROVs. A number of manufacturers, including Seabotix, are making mini and small production HROV models. Canada’s ISE has experimented with HROVs as a way to reduce monitoring costs. According to interviews conducted by CGGC, HROV configurations are expected to be an option increasingly offered by ROV manufacturers, particularly in the mini and small ROV markets. AUV market and technology trends. The AUV market is smaller than the ROV market. According to industry interviews conducted by CGGC, the global annual expenditure on AUVs is roughly $200 million, dominated by U.S. manufacturers. Currently, the military/security market makes up approximately 50% of AUV sales. The scientific research market makes up approximately 30% of the AUV market. The oil and gas market makes up approximately 20% of AUV sales. The market is expected to grow to $2.3 billion by (Westwood, ). Interviews with leading AUV manufacturers consider the 30% compounded annual growth rate implied by this forecast to be optimistic. However, the growth potential of AUVs is clearly large. Military and scientific research markets are expected to make up more than 75% of projected sales through (Westwood, ). AUVs increasingly will be used in the oil and gas market, primarily due to the cost of using ROVs. The increased functionality in AUVs and the demand for floating oil production systems and remote fields also are drivers for adopting AUVs. The majority (~70%) of AUVs sold are rated for water depths less than 200m, illustrating the importance of small, light, shallow water AUVs for various end-markets. Of these shallow water AUVs, roughly 30% are rated for depths less than 30m. Unit sales forecasts through estimate that the majority of sales will occur in small AUV sales. However, large AUVs will dominate the projected $2.3 billion sales because of their high unit costs. AUVs are still a relatively new ocean technology. The first recorded sale of an AUV occurred in ; 75% of existing AUVs were produced between and . As newer technologies, the platform costs are greater than the instruments onboard. In contrast to ROVs, the AUV vehicle makes up the majority of the total cost of the vehicle. AUV platforms make-up, on average,66-75% of the cost (in comparison to 40% for ROVs), while instruments make-up 25-33% of AUVs. This of course depends on what instruments are included in the AUV. Some instruments (e.g., spectrometers, dissolved gas and nutrient sensors) are relatively expensive, while others (e.g., altimeters and pressure gauges) are inexpensive. The platform’s share of the total AUV cost is expected to decrease as incremental innovations in the vehicle are implemented. The technology trends in AUVs are increased functionality, longer mission life, reduced power requirements, and miniaturization. The trend in AUV technology is to increase their versatility from what essentially is an oceanographic data collection system to perform a greater variety of missions. AUVs are capable of mission lives up to a year, although this varies on the type of vehicle and amount of instrumentation onboard. Generally speaking, the greater the number of instruments onboard an AUV, the shorter its mission-life. AUVs have also been used in place of towed ROVs because of higher resolution capability made possible by reduced processing requirement when survey sensors are co-located on the vehicle. AUV surveys in deep water (> meters) are conducted two to three times faster than in towed systems because AUVs have higher cruising speeds, do not require repeated turns and passes over the same locations, and provide higher data quality because of the stability of the survey platform. AUVs are currently being developed in the military market for locating and disabling mines. The University of Hawaii and the U.S. Navy’s SAUVIM (Semi-Autonomous Underwater Vehicle for Intervention Missions) performed the first autonomous manipulation (the use of a programmable robotic arm) using feature based navigation in January, (MASE, ). Scripps Oceanographic Institute, the University of Washington, and the U.S. Navy developed the XRay Flying Wing prototype to track submarines and conduct remote sensing in shallow waters for up to 6 months. A second trend is to increase the mission life of AUVs. Current AUVs can be deployed up to a year, after which batteries must be replaced and the vehicle reconditioned. The limitation on mission life is largely a power imposed constraint – the vehicle simply runs out of power to conduct its mission. Three developments have sought to address this limitation of AUVs. The first is the development of compact battery technology capable of storing more electricity. The second development is instrumentation and communication devices requiring less power. The third development is onboard power generation, either through the use of solar arrays kept above the ocean surface, or for gliders, through wave and bio-mimicking technology to power the vehicle. These developments could dramatically increase the mission life of AUVs. A third trend is to reduce the power requirements for AUVs. Two power requirements exist for an AUV: forward propulsion and power for onboard instrumentation, guidance, computers, and communication devices. Forward propulsion for most AUVs is generated from power stored in onboard batteries. This limits the mission life of AUVs since physical limitations on the number and size of batteries carried onboard exist. The weight of batteries is a key drawback since they reduce the payload available for other instrumentation. Gliders have overcome some of these difficulties by using changes in the vehicle’s buoyancy and onboard wings to propel the vehicle forward. Advances in mechanical design, particularly bio-mechanical engineering, may reduce or eliminate the need for stored onboard power in gliders in the near future. Researchers at the California Institute of Technology (US), Southampton (UK), Tokai University (Shizuoka, Japan), and the Delft University of Technology (Netherlands) have recently presented papers on biomechanical applications to AUVs. Most production glider models require stored power to bring the vehicle up at the end of its dive cycles. Onboard electronics are currently powered with onboard batteries or solar arrays. The use of solar arrays limits the depth the vehicle can dive; however, for extended ocean gathering and monitoring this configuration is well suited to the mission goals. The fourth major trend in AUVs is miniaturization of onboard instruments and vehicles. The application of nanotechnology to robotics and electronic equipment holds tremendous potential to develop small, highly sophisticated underwater vehicles. While the promise of nanotechnology continues to develop, AUVs have continued along the same path as ROVs to become smaller while simultaneously adding capabilities. The cooperation between platform builders and instrument manufacturers has been important in developing small, light, and low-power consuming instruments for AUVs.
