The invention discloses a marine winch heave compensation device and method. In the device, a main loop is connected with a hydraulic transformer, an electromagnetic valve and a roller mechanism, the electromagnetic valve is further connected with a braking mechanism and an energy storage part, the roller mechanism, a pulley block and a drill column are sequentially connected, and the hydraulic transformer is further connected with the energy storage part; the main loop comprises a one-way variable hydraulic motor, an overflow valve, a one-way valve and a two-way variable hydraulic motor, and the roller mechanism rotates forwards and backwards through the hydraulic motor, so that the pulley block drives the drill column to ascend and descend; the hydraulic transformer transmits the power, adjusts the pressure and changes parameters; the energy storage part is a leather bag type air charged energy accumulator for storing hydraulic oil; the roller mechanism rotates forwards and backwards to pull a cable in the pulley block; and the braking mechanism is subjected to braking control by the main loop through the electromagnetic valve. According to the device and method, compensation for ascending and sinking of the drill column is achieved based on hydraulic compensation.
