Abstract: The invention is a method for mooring a marine vessel (P) using three or more anchor lines (11a, 11b, . . . ) comprising—laying out each anchor line (11) with an anchor in a desired position relative to the platform, with a seabed anchor chain (10) extending towards the desired position of the platform (P), with the seabed chain (10) connected to a fiber rope's (20) arranged for being extended through the sea and connected to an anchor winch chain (30) and being tightended by an anchor winch (31) on the vessel (P), wherein the fiber rope (20) is prepared by being packed to a bundle or coil (21) arranged in a protective container (24) on the seafloor, and arranged for being released and pulled out of the container (24) at a predetermined pulling force, and arranged for being picked up and connected to the anchor winch chain (30).

Abstract: A releasable coupling device, especially for use in lifting devices has one or more couplings (3) that are arranged in the lifting equipment (2) or between the lifting equipment (2) and the load (1). The coupling is locked or opened directly or indirectly through a positional or rotational change of a locking element (23), which is brought about directly or indirectly by the buoyancy of a floating element (36) or other external force applied. Structural change of one or more metals may be used directly or indirectly to change the position of a release-blocking/locking element (39, 45) between a locked and an unlocked position. This structural change allows imitation through cableless remote control by the use of auxiliary equipment of a known type. Memory metal(s) can be used to change the position of the release-blocking/locking element (39, 45) between a locked and an unlocked position.
