Abstract
A method and system are provided for reducing sea state induced vertical motion of a shipboard crane's load. Sea state induced vertical velocity of the crane's suspended load is determined as a function of: i) the horizontal radial distance the load extends from the crane's axis of rotation, and ii) motion of the ship at the crane's axis of rotation. The load is then moved vertically at a speed that is defined as being equal to the vertical velocity in a direction that is opposite that of the vertical velocity.
