<p>A method for transferring a load between objects, such as a fixed structure (1) and a vessel (2), subjected to relative heave motions as a result of swell, comprises the steps of: - providing one of the objects, such as the fixed structure (1), with a hoisting means (3) and a heave compensator (4) which cooperates with said hoisting means (3), - providing the other object with a load, - connecting said heave compensator (4) to the load by means of a hoist (5) which is in a slack condition, -diminishing the amount of slack in the hoist (5), - making the hoist (5) become taut, - making the heave compensator (4) follow the heave motion while the hoist (5) is taut, - establishing the occurrence of an upward hoist motion, - making the heave compensator (4) become blocked during said upward hoist motion so as to prevent downward hoist motions while allowing upward hoist motions.</p> |
