Embodiment Construction

[0024] Figure 1 shows an offshore structure 1 such as a newly constructed FSRU or a newly constructed floating production storage offloading unit FPSO that changes orientation with the wind. The structure 1 comprises a hull 2 ​​with longitudinal sides 3, 4 and transverse sides 5, 6 at the bow and stern. A tanker 7 is moored along the structure 1 via groups of mooring lines 8, 9 at the bow and stern. The bow mooring lines 9 (beam lines) comprise three groups 10 , 11 , 12 of two parallel mooring lines each, which are attached to six bow anchor points 13 on the structure 1 . The rear mooring lines 8 (cross lines) also comprise three groups of two parallel lines each, attached to the stern anchor points 14 on the structure 1 . Elastic mooring lines 16, 17 extend from aft and forward positions respectively on the vessel 7 towards anchor points on the structure 1 near midship. A number of elastic fenders 20 , 21 are located between the tanker 7 and the structure 1 against which th...

Abstract

The invention relates to a floating offshore structure (1) anchored to the sea bed (2) . The floating offshore structure (1) comprises a hull (12) having longitudinal sides (3, 4) and transverse sides (5, G) , 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 hight (Hl) above sea level, hydrocarbon storage and / or processing devices (26) being placed on the main 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 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) .

Description

technical field [0001] The invention relates to a floating offshore structure anchored to the seabed, comprising longitudinal and transverse sides, bow and stern anchor points for mooring tankers along said offshore structure, a deck at a predetermined height above sea level, A hydrocarbon storage and / or processing unit placed on deck, attached to the structure and protruding laterally from the sides to contact a bulkhead of a tanker moored along the structure. Background technique [0002] It is known to moor two LNG carriers in a side-by-side configuration. An anchor cable runs between the transport ships and tensions the transport ships against a dividing member in the form of a fender located between the two transport ships. In known mooring arrangements, carriers are of substantially similar dimensions and are attached with mooring lines of length less than 10 m, for example 8 m. A side-by-side mooring configuration at sea responds to environmental conditions as a sin...
