Vessel, motion platform, method for compensating motions of a vessel and use of a Stewart platform

A method for compensating for motion of a boat as it floats on water, comprising the steps of:

• measuring, with a control system, motion of the boat floating on water relative to at least one other element in an area surrounding the boat;
• generating, with the control system, a respective driving signal for each of six hydraulic cylinders of a Stewart platform, each of the six hydraulic cylinders operatively associated between the boat and an at least one carrier, based on the motion of the boat;
• driving, with the control system, the six hydraulic cylinders of the Stewart platform to hold the at least one carrier substantially stationary relative to the at least one other element in the area surrounding the boat, wherein the six hydraulic cylinders move the at least one carrier relative to the boat based on the respective driving signals;
• and
• relieving weight on the six hydraulic cylinders of the Stewart platform by at least partly bearing the weight of a load and the at least one carrier by means of at least one at least partly passive pressure element operatively associated between the at least one carrier and the boat, the at least one at least partly passive pressure element applying a counter-pressure on the at least one carrier that acts against a gravitational force of the load and the at least one carrier.
