ABSTRACT:
A marine vessel having backup power storage in the event of primary power source failure. The invention applies to different marine vessels and is particularly suited to vessels used in marine seismic operations. A rotating mass energy storage provides stored energy which can be distributed to the vessel following primary power source failure. A pulsed generator charges the energy storage means, and the pulsed generator can comprise a homopolar generator or a compensated pulsed alternator. The primary power source can recharge the energy storage means, and a sensor and controller can control different functions related to the control and operation of the primary power source and the energy storage means
