HYBRID WINCH WITH CONTROLLED RELEASE AND TORQUE IMPULSE GENERATION CONTROL FOR ANCHOR HANDLING OFFSHORE

摘要

A hybrid winch system for use with an anchor handling vessel is disclosed that includes but is not limited to an electric winch mountable on the anchor handling vessel, an electric generator for providing generated power to the electric winch, a battery for providing stored power to the electric winch, an anchor cable wound around the electric winch and passing over a roller drum for guiding the anchor cable, an anchor attached to a distal end of the anchor cable and a winch controller for selectively applying the generated power and the stored power to the electric winch. The winch controller is configured to provide the stored power to the electric winch for controlled release of the anchor cable in the case of loss of the generated power.
