  • Submersible ROV for cleaning and inspecting metal
    Patent number: 4821665
    Abstract: A submersible ROV removes extraneous material from the surface of submerged metal with a cleaning tool and measures the thickness of the metal with an ultrasonic probe. A camera allows visual operation of the ROV. The cleaning tool and ultrasonic probe can reach areas of limited access making the ROV useful for inspecting the interior of holding tanks. A submersible, electrical power supply can be combined with the ROV to provide an intrinsically safe system which is particularly useful in environments where sparks pose a substantial hazard.

  • Submersible electrical power supply
    Patent number: 4808837
    Abstract: An electrical generator in a water impermeable housing is driven by a water driven motor. The combination can be submersed with power delivered from the generator to a hydro-subsystem. The system is intrinsically safe in that all electronics are submerged during operation, thus any sparks emitted will not trigger secondary explosions in the surrounding environment. The supply is particularly useful in conjunction with submersible, remotely operated vehicles (ROVs), and diver assist power supply.
