Abstract
Described is a method for lifting an object from a vessel deck. A hoisting means present on the vessel deck is provided with a hoisting cable to which an attaching means for the object is coupled. The object is connected to the attaching means and then taken up and displaced relative to the vessel deck using the attaching means. The swinging movements of the attaching means and of the object connected thereto, occurring under the influence of wave and wind forces, are damped during displacement by a gyroscope which is connected to the hoisting cable, attaching means and/or object and which includes a rotation-symmetrical body rotating around a primary rotation axis.

A method for lifting an object from a vessel deck and transporting the object, wherein a hoisting means on the vessel deck comprises a hoisting cable which is provided at an outer end with an attaching means for the object, wherein the object is connected to the attaching means and the object is taken up and displaced relative to the vessel deck using the attaching means, wherein the swinging movements of the attaching means and of the object connected thereto, occurring under the influence of wave and wind forces, are damped during displacement by a gyroscope which is connected to the hoisting cable, attaching means, or object, and which comprises a rotation-symmetrical body rotating around a primary rotation axis, wherein the primary rotation axis of the gyroscope is held at an angle of inclination other than zero to the hoisting cable direction, wherein the angle of inclination is varied linearly with the current angle of swing between the hoisting cable direction and a z-direction running perpendicularly of the vessel deck.
