Abstract
A motion-state dependent method for operating a kinetic generator on a marine vessels or platform includes determining a motion state of the marine vessels or platform, and imposing a limit on at least one of charging and discharging of the kinetic generator based upon the motion state to keep the kinetic generator within a safe operating range.
Claims21
A motion-state dependent method for operating a kinetic generator on a marine vessels or platform, said kinetic generator configured to
- (a) convert electric energy, supplied thereto, to kinetic energy of a rotor of the kinetic generator and
- (b) convert stored kinetic energy of said rotor to electrical energy when an electrical energy output from the kinetic generator is required,
- the method comprising:
- determining a motion state of the marine vessels or platform;
- and
- imposing a limit on at least one of charging and discharging of the kinetic generator based upon the motion state to keep the kinetic generator within a safe operating range.

A control system for motion-state dependent operation of a kinetic generator on a marine vessels or platform, comprising:
- a processor configured to be communicatively coupled to the kinetic generator;
- an interface, communicatively coupled with the processor, for receiving a sensor signal indicative of a motion characteristic of the marine vessels or platform;
- and
- a non-transitory memory including machine-readable instructions that, upon execution by the processor, perform steps of:
- processing the sensor signal to determine a motion state of the marine vessels or platform, and
- imposing a limit on at least one of charging and discharging of the kinetic generator based upon the motion state to keep the kinetic generator within a safe operating range.

18-20. (canceled)
A kinetic generator system for motion-state dependent operation of a kinetic generator on a marine vessels or platform, comprising:
- one or more kinetic generators including a rotor and a magnetic induction coupling capable of (a) accelerating rotation of the rotor to convert electrical energy to kinetic energy stored in the one or more kinetic generators and (b) decelerating rotation of the rotor to generate electrical energy from stored kinetic energy;
- at least one sensor for generating one or more sensor signals indicating at least one motion characteristic of the marine vessels or platform;
- and
- a control module for (a) based upon the one or more sensor signals, determining a motion state of the marine vessels or platform, and (b) imposing a limit on at least one of rate of said accelerating and rate of said decelerating based upon the motion state, to keep the one or more kinetic generators within a safe operating range.
