Abstract
The present invention is a linear actuation system comprising a reversible screw type linear actuator, equipped with at least one reversible electrical motor system and energy storage. The energy storage is charged by linear actuation system functioning as a generator when a mobile rod of the linear actuator is moved by heave and is discharged when the mobile rod is moved by activation of an electric motor of the linear actuation system motor.
