PCT No. PCT/NO93/00043 Sec. 371 Date Sep. 12, 1994 Sec. 102(e) Date Sep. 12, 1994 PCT Filed Mar. 16, 1993 PCT Pub. No. WO93/18999 PCT Pub. Date Sep. 30, 1993A method and apparatus for the transfer of loads from a vessel that moves with heavy seas to a stationary or mobile installation by the use of at least one lifting cable and at least one hoisting mechanism, where the load, in a starting position, stands on a rack on the vessel. The load transfer takes place at an instant when the load has only insignificant kinetic energy, as the gripping mechanism is activated in a controlled manner at the instant to lock the load to the lifting cable. At the same instant the rack collapses and immediately establishes a distance between the load and the vessel, thereby suspending the load on the lifting cable.
