ABSTRACT:
Method and apparatus for transferring cargo between an ocean-located unit and a vessel by way of a loading crane or derrick with associated winch and especially at sea under conditions of heavy wave movement. A cargo-supporting hook is subjected during loading and unloading to a controlled wave movement relative to the loading crane or derrick which corresponds to the relative movement between the ocean-located unit and the vessel and is in step with this relative movement.
