Abstract
An energy management system of a Remotely Operated Vehicle (“ROV”) has a generating unit located in a remote station on a water body and configured to generate a generated electrical power with a first maximum value); a ROV configured to operate in the water body and configured to absorb a second maximum value of an absorbed electrical power greater than the first maximum value; an electrical energy transmission line connected to the generating unit and to the ROV; and an electrical energy storage device located along the transmission line and/or on board the ROV.

1-15. (canceled)
A remotely operated vehicle energy management system comprising:
- an electrical power generation unit locatable in a remote station on a body of water, the electrical power generation unit configured to generate electrical power with a first maximum value;
- a wire-guided remotely operated vehicle configured to operate in the body of water and absorb a second maximum value of electrical power that is greater than the first maximum value;
- an electrical energy transmission line connectable to the electrical power generation unit and to the remotely operated vehicle, the electrical energy transmission line configured to transmit electrical energy from the electrical power generation unit to the remotely operated vehicle;
- and
- an electrical energy storage device locatable at at least one of:
- along the electrical energy transmission line and on the remotely operated vehicle.
A method of managing energy of a remotely operated vehicle, the method comprising:
- generating electrical power through an electrical power generation unit having a first maximum value of generated electrical power, the electrical power generation unit being located at a remote station on a body of water;
- absorbing, through the remotely operated vehicle in the body of water, a second maximum value of electrical power, the second maximum value being greater than the first maximum value;
- transmitting, via an electrical energy transmission line, electrical energy from the electrical power generation unit to the remotely operated vehicle;
- responsive to a first difference between the absorbed electrical power and the generated electrical power, accumulating electrical energy by an electrical energy storage device located along at least one of the electrical energy transmission line and on the remotely operated vehicle;
- and
- responsive to a second difference between the absorbed electrical power and the generated electrical power, delivering, via the electrical energy storage device, electrical energy to the remotely operated vehicle.
