  • ROV Mantis: A dual-purpose underwater vehicle

    This paper reviews the last two years operational deep-water performance record of two manned/unmanned tethered ROV Mantis vehicles. Deviations of the system as compared to conventional submersibles and remotely operated vehicles (ROV's) are discussed and evaluated. Applications and advantages of this system in support of deep-water operations are appraised. Results and observations concluded in this paper deal with the importance of having a man in the water, or at least available to go in the water, and also those circumstances which require a remotely operated system either for safety or total bottom time requirement. The significance of each mode of operation is examined. Observations and conclusions have been compiled from operational data collected during over 250 actual dives in deep-water work to depths of 2000 ft (<tex>\sim 600</tex>m).

  • Measurement of electromagnetic fields produced by underwater equipment

    The elasmobranchii (sharks, rays and skates) possess sensory organs called the Ampullae of Lorentzini which enables them to detect electromagnetic (EM) fields at intensities as low as 1 /spl mu/V/m at frequencies between 0.1 and 16 Hz. This paper describes the laboratory based measurement system used to measure the EM fields produced by commercial and recreational electronic scuba diving equipment. Using these measurements and software modelling, predictions can be made concerning the distance at which the elasmobranchii would be able to sense the presence of such equipment or the intensity of the fields at any given distance from the source.

  • Rapture of the deep

    He makes the dive computer that every aquanaut wants. On one of the last shimmering days of summer, two weathered, middleaged men undress in a parking lot on the northeastern shore of Lake Zurich. This is the city's Gold Coast, where a halfway decent villa will set you back a couple of million francs. Jabbering in a Swiss dialect while working with swift, sure hands, the divers pull on thick black exposure suits and 20 kilograms of gear, including two big steel cylinders of pressurized breathing gas.

  • Saving navy SEALS: Pressure-activated system for personal flotation device

    Approximately 2000 operators in the SEAL Teams use a personal flotation device (PFD). While it is a necessary safety measure, the current PFDs in use often deploy prematurely causing the operator to then discard the device. We created a system with changeable modes, allowing the user to retain a fully functional vest with an activation system that is not subject to premature deployment. Implementation of this will reduce the danger for each operator and save lives. Our system is composed of a sensor suite, microcontroller, and actuator. The system has two user chosen modes: automatic and manual. We performed system tests to ensure the system is reliable and validated for use in special operations. Two of these tests included a software functionality test (A) and a valve response test (B). Results for (A) were LED ON for deployment conditions and LED OFF for non-deployment conditions. Results for (B) were a positive result (actuator activated and filled bladder correctly) for each test. The final result was an automatic PFD system that is viable for use in special operations. This will increase the number of lives saved by ensuring that operators can retain their PFDs without premature deployment as well as ensuring that an unconscious victim in the water will be lifted to safety by their automatic PFD.

  • Unidentified floating objects

    The oceans cover nearly three-quarters of Earth's sur face, yet to this day they remain dark and largely unexplored frontiers. By casting some light on the ocean with wide-area sonar, we hope we can help to preserve marine life. Perhaps one day fixed sonar platforms will scan the ocean much as fixed radar stations currently monitor weather and bird migrations on land. If used responsibly-perhaps by delaying the release of the data for a month or two-the information gleaned would provide marine biologists with a valuable scientific resource without compromising the sea creatures it reveals.

  • New approach for a Reconfigurable Autonomous Underwater Vehicle for Intervention

    This shows an on-going project named RAUVI (i.e., Reconfigurable AUV for Intervention). This project aims to design and develop an Underwater Autonomous Robot, able to perceive the environment by means of acoustic and optic sensors, and equipped with a robotic arm in order to autonomously perform simple intervention tasks. A complete simulation environment, including this new concept of robot, has been developed and is presented as a preliminary result.

  • Thermoelectric generator for underwater wellhead

    DCN CHERBOURG, the French submarine builder, has a great deal of experience in underwater equipment. The company also has experience in thermoelectric technology which is used in submarines for cooling systems. In light of this experience, DCN CHERBOURG was contacted by an oil company in order to develop a thermoelectric generator for an offshore subsea application The requirements were: (i) a thermogenerator able to be inserted as a spool in a submarine pipeline; (ii) site: North Sea (sea water temperature=4/spl deg/C); and (iii) fluid: mix of oil and gas, temperature between 90/spl deg/C and 120/spl deg/C, pressure 450 bar. The design began with thermoelectric module tests (electrical, thermal and mechanical). The objective was to select the type of thermoelectric module and the assembly system. The ceramic technology from MELCOR was chosen. DCN CHERBOURG then made and tested a prototype. The performance results were not as good as expected, however, the prototype proved that a thermoelectric generator for an offshore subsea application was feasible. The next step was the assembling of two thermogenerators (THEGS) for an offshore application. The performance measurements obtained during on-shore testing were as expected: about 100 W at 70 V.

  • A SBE-19plus based real-time monitoring system of CTD Data

    This paper introduces the SBE-19plus SEACAT profiler and points out the problems exist in its applications. To solve the problem of limited energy and to get CTD data real-time display with easy operation, the paper gives a brief design of remote power supplied CTD real-time monitoring system and its detailed software design. Finally, the paper gives the test result which proves that the system can accurately monitor real-time changes in ocean CTD data.

  • Reliable and Opportunistic Transmissions for Underwater Acoustic Networks

    Acoustic waves propagate slowly in water, and time-varying UACs result in inevitably high bit error rate and packet loss rate. The long propagation delay and the error-prone nature of UACs impose challenges on reliable transmissions in UANs. In this article, we identify the challenges for reliable acoustic transmissions and propose a CL-FEC scheme, which achieves opportunistic transmissions to overcome the frequent transmission failures in UACs. CL-FEC adopts fountain codes as a packet-level FEC and adopts channel codes as a bit-level FEC, to realize reliable transmissions over UACs without per-packet feedback. To further improve the throughput of CL-FEC, we formulate the transmissions over UACs into a stochastic throughput optimization problem. A discrete stochastic approximation based algorithm is then developed to achieve the optimal CL-FEC by online exploiting channel estimating and algorithm iterations. Simulation results show the asymptotic convergence and the iterative optimality of the algorithm.

  • Review of Electrical Connectors for Underwater Applications

    The history of underwater electrical connectors is relatively new: In 1858, the first transatlantic communication cable was created. Since then, the need for subsea electrical connectors has been growing very fast in the offshore industry. Today numerous companies offer a large choice of underwater connectors and assemblies, and it can be intricate to distinguish the different technologies employed for each of them. However the use, deployment, maintenance, and lifetime of any subsea equipment, from a simple sonar to a wave energy converter, relies on its connectors. Hence the design of an underwater electrical connector is to be carefully looked at, and especially for tailor-made applications that have more specific requirements. To produce a good connector, it is necessary to account for thermal, electrical, and mechanical properties, as well as to determine the best materials that should be used for the application. Finally, connector issues go hand in hand with the deployment and operation of any electrical equipment, and it is of interest to review the different techniques for cable connection, as well as the challenges related to cable layout. Those challenges can be of different nature, but they should all be taken into account for any subsea connection.
