Patent ID: 8672288

Claim:
A boat comprising: a motion compensation platform attached to the boat for compensating for motion of the boat as it floats on water, the motion compensation platform comprising: at least one carrier for bearing and transferring a load to or from the boat floating on water; actuators operatively associated between the boat and at least one carrier, for moving the at least one carrier relative to the boat; a control system, for driving the actuators; and motion sensors for measuring motions of the boat floating on water relative to at least one other element in an area surrounding the boat, which measurements are used as input for the control system to drive the actuators to hold the at least one carrier substantially stationary relative to the at least one other element in the area surrounding the boat; and at least one at least partly passive pressure element operatively associated between the carrier and the boat configured to apply a counter-pressure on the carrier that acts against a gravitational force of the load and the carrier, and relieves weight on the actuators by at least partly bearing the weight of the load and the carrier.
