Abstract (en)
The invention provides a permanent single point mooring structure in which the vessel (1) is moored to a single point mooring tower structure (4) via a rigid arm assembly (11, 12). The vessel (1) and rigid arm assembly (11, 12) are free to rotate about the vertical axis (9) of the tower structure (4). The rigid arm assembly (11, 12) is connected to the vessel by a hinge arrangement (13, 14, 15, 16) and to the turntable (8) of the tower structure by two tension members (23, 24). The rigid arm assembly (23, 24) is ballasted at the towerend (19, 20). These ballast weights (21, 22) provide a stable pendulum in combination with the tension members (23, 24). The weight of the rigid arm (11, 12) and its ballast (21, 22), and the loading on the tension members (23, 24) combine to produce a restoring force and moment which prevent the vessel (1) from moving away or from riding up to the tower structure (4), or jack-knifing of the assembly when the vessel (1) is affected by any combination of wind, waves and current.
