Abstract: The invention is directed towards a passive heave compensation arrangement for compensating for heave events in the open water, when loading or offloading/launching objects. The arrangement is part of a system that includes a water vessel that is operating on open water, a davit, and an object to be loaded/offloaded. The davit includes a stanchion, a boom, and a capture head for capturing objects within the head. The arrangement includes first and second winches, as well as a gas spring that applies forces to the boom in response to heave events, the gas spring as a part of the arrangement, passively compensating for every heave event.
