A winch is provided including a rotatable drum and a gear train drivingly connecting a motor to the rotatable drum. The gear train includes a clutch that is operable to be disengaged to allow the rotatable drum to free spool. A clutch actuator is provided for disengaging the clutch and the clutch includes a pivoting pawl having a first end that engages a clutch dog of a planetary ring gear and the clutch actuator includes an electro-magnetic solenoid having a plunger that engages a second end of the pivoting pawl.

A system and method for deploying seismic data acquisition equipment from a moving vessel. The system and method utilize movable pulley systems to manipulate a string of data acquisition equipment such that a technician may attach the seismic data acquisition equipment to a rope or cable during a period in which the rope or cable is stationary relative to the vessel. The system and method allow for equipment deployment at a relatively constant rate while the vessel maintains a relatively constant velocity. The system and method for deploying seismic data acquisition equipment allows for enhanced personnel safety and efficient equipment deployment.

Methods and systems are provided for adjusting operation of a motor of a winch. In one example, a system for a winch includes a controller adapted to adjust operation of a motor of the winch based on one or more of and/or each of a winch load limit, a motor temperature, a distance of a hook coupled to an end of a rope of the winch to a winch fairlead, and an amount of rope wound onto a drum of the winch.

Methods and systems are provided for a winch including a motor and a contactor assembly coupled around the motor. In one example, the contactor assembly is coupled around and in face-sharing contact with a portion of an outer surface of the motor. Additionally, the contactor assembly may include two or more coils spaced apart from one another within the contactor assembly.
