Abstract
A method provides power to a subsea equipment electrical system underwater, without a wet-mated electrical connection. The method includes temporarily coupling a rotary coupling element of a power source to the subsea equipment and turning that element to generate electric power on board the equipment. Subsea equipment that implements the method comprises: an on-board electric power generator connected to an electrical load such as a rechargeable battery to charge the battery when the generator is driven; and a rotary coupling element that is turned by an external drive to drive the generator. Alternative subsea equipment to implement the method comprises: a stator, but not a rotor, of an on-board electric power generator, which supplies current to the load when an externally-driven rotor is positioned adjacent to the stator and turned relative to the stator. A power source having a generator rotor is docked with the equipment for this purpose.
