Abstract: A power converter for subsea use, for example for powering Remotely Operable Vehicles, comprises an electric motor (2) driving an electric generator (5) inside an external vessel (1) which may be a pressure vessel containing a gaseous atmosphere, for example. The motor and generator may be both AC machines, both DC machines, or combinations of these. Alternatively, an AC supply may be rectified to DC to power a DC motor. Equally, AC output of the generator can be rectified to provide a DC power output. Input electrical power to the motor is from an external source via a cable (3) while the output electrical power from the generator (5) passes through a cable to power an external device.

Abstract: A device and method for sampling underwater parameters is provided. The device is configured to be removably secured to, and navigated along a length of, an underwater cable during an underwater cable recovery operation. The device may include one or more sampling elements configured to sample underwater parameters while the device moves along the length of the underwater cable. The device may include a computing unit in communication with the one or more sampling elements which is configured to receive output data of the one or more sampling elements and record the output data for subsequent analysis.

Abstract: The invention relates to the field of special purpose robotic systems to conduct external functions such as cleaning, monitoring and inspection of structures such as tubular assets in a splash zone. The splash zone is defined as the section of a marine structure that is periodically in and out of water due to the action of waves or tides, usually falling within (+)10m to (-)20m water depth. In embodiments, splash zone inspection robot system (1) comprises station (300), submersible saddle (350), submersible robot (400), and subsea robot controller (308). A predetermined set of controllable clamps selectively secure submersible robot (400) to submersible saddle (350) or structure (2) and allow incremental traversal along submersible saddle (350) or structure (2).

Abstract: The invention provides an underwater cleaning device, which includes a body onto which at least one rotatable scouring device is mounted, arranged to project from a working face of the body, at least one motor drivingly connected to the at least rotatable scouring device and a suction intake positioned proximate the at least one rotatable scouring device for collecting fouling displaced from a submerged surface by the at least one rotatable scouring device, when in use. The invention further described an underwater cleaning system, whereby the underwater cleaning device is adherable onto a surface of an underwater object in order to detach fouling therefrom and to capture the fouling-water suspension by means of the suction intake and a water treatment plant connected downstream and in flow communication with the suction intake, operable to purify the fouling-water suspension being collected from the suction intake.
