Embodiment Construction

[0032] Figure 1 shows a cryogenic unloading system 1 according to the invention. The system includes an LNG carrier 2 and an inshore mooring structure 3 . The near shore mooring structure 3 comprises a buoy 4 attached to a cable platform 5 . The cable platform 5 is tied to the sea bottom 6 by anchor chains or mooring lines 7 . The upper part 8 of the buoy 4 is rotatable relative to the stationary part 5 about a vertical axis 9 . The buoys 4 are connected to the ship 2 by connecting members or space frames 10 extending next to the ship 2 . The frame 10 is attached by a first end 22 to the buoyant structure 12 on which the treatment device 13 is placed. The processing plant 13 in the embodiment described here is a regasification plant, but may include other LNG processing plants, such as LNG booster stations or gas liquefaction facilities.

[0033] It can be clearly seen in FIG. 2 that the buoyant structure 12 is moored next to the ship 2 . Both the processing means 13 and ...

Abstract

The invention relates to a cryogenic fluid offloading system, having a tanker vessel (2) moored in line with an offshore mooring construction (4, 8) and connected to a processing unit, such as regasification plant (13). The regasification plant (13) has no large storage facilities, the tanker (2) being unloaded in dependence on onshore demand for gas.

Description

technical field [0001] The present invention relates to a cryogenic fluid unloading system, which includes: [0002] - an inshore mooring structure connected to the seabed, [0003] - a connecting member, which by a first end will be attached to the mooring structure so as to be movable in position around a vertical axis, [0004] - a tanker vessel for loading the cryogenic fluid at a first location and transporting the cryogenic fluid to a second location for unloading, which is connected to the mooring structure by connecting members, [0005] - a first fluid conduit connected to the mooring structure for supplying fluid from the mooring structure outwards, [0006] - a second fluid conduit for transferring fluid from the tanker to the mooring structure, [0007] - processing means for receiving liquid-phase cryogenic fluid in the tanker and supplying gas-phase fluid into the first fluid conduit, and [0008] - Fluid supply means for controlling the supply of cryogenic f...
