Claim 16:
17. A method for controlling a motion compensated pile guide for a floating vessel during driving a monopile into a seabed, wherein the monopile is guided in its longitudinal direction by the pile guide and the pile guide is moved in a horizontal direction for compensating motion of the floating vessel to which the pile guide is mounted, said method comprising,
determining an inclination angle of the monopile with respect to vertical and a magnitude and direction of an actual force of the monopile onto the pile guide during driving the monopile into the seabed,
determining a desired force of the pile guide onto the monopile for minimizing the determined inclination angle, and
moving the pile guide in a direction opposite to the direction of the actual force when the desired force is larger than the actual force and in a same direction as the direction of the actual force when the actual force is larger than the desired force.
