The invention relates to a fluid transfer system, in particular for LNG in which an articulated vertical and horizontal mooring arm are suspended from a support on the processing vessel. Independently moveable ducts, for instance cryogenic hard piping are placed parallel to the mooring arms such that a transfer system is obtained in which is the mooring forces are insulated from the fluid transfer line with which rapid connection and disconnection is possible and which provides a large yaw resistance. In a preferred embodiment, the mooring system comprises two vertical arms connected to a triangular horizontal yoke attached to the bow of the LNG-carrier for improved yaw resistance.

The invention relates to a buoy comprising a buoyant body (1) with anchoring means (6), a turntable (2) on said body (1) with means (8, 8', 8") for mooring a ship. According to the invention the turntable (2) has buoyancy as well and preferably takes part in the water displacement of the buoy. The bearing (4) between turntable and body being preferably above water level between a central sleeve (3) of the body and the turntable (2), accessible from above and located in the line from mooring point on the turntable to chain stopper (5) on the body.

The invention relates to a cryogenic fluid offloading system, having a tanker vessel for loading liquefied gas at a first location, transporting it and offloading the liquefied gas at a second location, the tanker vessel being connected to the mooring structure via the connecting member. The regasification plant has no large storage facilities, the tanker being unloaded in dependence on onshore demand for gas.

The invention relates to a floating offshore structure (1) anchored to the sea bed (30). The floating offshore structure (1) comprises a hull (2) having longitudinal sides (3,4) and transverse sides (5,6), bow and stern anchoring points (13,14,40) for mooring a tanker vessel (7) alongside the offshore structure (1), a main deck (25) at a predetermined height (H1) above sea level, hydrocarbon storage and/or processing devices (26) being placed on the deck (25), a spacer member (20,21) attached to the structure (1) and projecting transversely from the sides for contacting a tanker vessel (7) moored alongside the structure (1). The anchoring points (13,14,40) of the structure comprise of quick release members (60), wherein the bow and/or stern anchoring points (13,14,40) of the structure (1) are situated on a secondary deck (28,39,51) which projects transversely from the hull (2) of the structure (1) substantially at the heights (H2) of anchoring points (34,35,36) of the tanker vessel (7).

The invention relates to a vessel (1) comprising at least two anchor lines (3,5) connected respectively at a substantially fixed position near the bow (2) and near the stern (4) of the vessel. At least one of the anchor lines comprises at least two branching anchor lines each connected with one end to the anchor line in a connection point (9,10) and connected with the other end (11,12) to the seabed. By means of this system, a stable anchoring arrangement is achieved in which the sides of the vessel are easily accessible by for instance a shuttle tanker. Furthermore the system according to the invention allows for a weathervaning action through relatively small angles, for instance between 0° and 90°. In another embodiment according to the present invention, at least one of the anchor lines is connected to a substantially fixed position pulling system such as a winch system for lengthening or shortening the anchor lines. For providing a weathervaning action through a range of about 0° and 90°, the anchor lines are maintained in a tensioned state by the winch system and are varied in length. In an embodiment the winch system varies the length of the anchor lines simultaneously. The anchor lines near the bow and the stern can be formed of a single anchor line which is connected to a single winch such that the anchor line which is payed out at the bow is taken in at the stern and vice versa.
