Abstract
Abstract Mooring system, comprising a mooring tower (3, 13, 22, 27), a ship (1) and a rigid arm (7, 15, 24, 31) between a horizontal pivot at the ship or the tower and a weight loaded tensionable connecting element (9, 29) suspended from the tower or the ship respectively, the system comprising a quick action coupling between the tower and the ship, as well as structure (12, 19, 20, 21, 26, 34) to control the behaviour of the disconnected arm.

Total Claims: 12
Claim 1
Independent Claim
148 words
Mooring system comprising a mooring device fixed relative to the water bottom, a floating device such as a ship, and a connection between the mooring device and the ship, comprising a rigid arm, one end of which is coupled rotatably about a horizontal axis, either to the mooring device or to the ship, while the other end is fixed to a tensionable connecting element, which is suspended from the other of the ship or mooring device and which is tensioned by a weight disposed adjacent one end of the arm, said connection having a quick-action coupling and means with which the position of the arm can be controlled after releasing the coupling to disconnect the mooring device and the ship from each other, said means being a chamber with adjustable buoyancy, adjacent to the quick-action coupling and adjacent to the end of the arm remote from the weight.
