Abstract: Device aboard floating craft for tightening/slackening of an elongated flexible element (13) such as a mooring cable that extends from a body of water up to the device (11, 12) is rotatably mounted about the longitudinal axis of the flexible element (13) directed towards the device (11,12).

Abstract: A mooring assembly for an offshore floater comprises a vertical shaft (4) in the floater (1), a rotating part (5) rotatably mounted in the vertical shaft about a vertical axis, a number of mooring cables (16) extending from the rotating part down to the seabed, and a device (17) aboard the floater (1) for tightening/slackening the mooring cables. Each mooring cable (15, 16) is secured, right below the rotating part (5), to a rigid body (13) having two ends, one end being connected by a universal swivel joint (12) to the rotating part (5) and the other end comprising a locking device (14) for locking the mooring line to the rigid body (13).

Abstract: A chain link (1) consists of two loops (2a, 2b) and two sides (3a, 3b), and a post (5) welded in between the chain link's sides (3a, 3b). The post (5) has sections (7) of reduced thickness against the chain link's sides (3a, 3b) in order to produce weld grooves for welding the post (5) to the chain link's sides (3a, 3b) with a through-weld. A sacrificial anode (9) is affixed around the chain link's post (5), by means of casting, welding or clamping.

Abstract: A submerged fairlead for a mooring line for use on a structure at sea is rotatably mounted in a swivelling elongated rigid tube mounted on the structure and through which the mooring line passes, and the free end of which is equipped with a line stopper. The tube is several meters in length. It causes direct transfer of the mooring forces to the structure when the line stopper is activated.
