A cryogenic transfer system includes: a cryogenic fluid storage and/or processing structure, an off shore loading and/or offloading structure having a base and a reel element rotatable relative to the base around an axis, a transfer duct extending from the fluid storage and/or processing structure to the loading and/or offloading structure, a flexible hose windable around the reel element, connectable with a first end to the duct, and with a second end to a floating structure. The transfer duct includes a first and a second duct, each having an end part at or near the loading and/or offloading structure, the flexible hose being with the first end connectable to the end part of at least the first or the second duct. The loading and/or offloading structure includes lifting elements.
摘要:
A hydrocarbon transfer system includes a first structure carrying an articulated arm. The system has at a free end a first connector part, and a vessel comprising a second connector part, wherein each connector part comprises a housing with at least two fluid ducts within the housing. The ducts can be placed into sealing engagement along respective sealing faces, and a locking member for locking the housings of the connector parts together, wherein the fluid ducts in either the first or second connector are connected to a respective fluid swivel or flexible duct section to allow at least partial rotation of the ducts along their longitudinal axis, and are connected to a drive member for jointly rotating the ducts along a centreline of the connector parts.
摘要:
An offshore hydrocarbon production system includes a vessel (12) with a turret (16), and a fluid swivel (50) on the turret that is connected to risers (41–43) that extend to the sea floor (26), wherein a drilling/workover rig (60) on the vessel can lower tubing (65) toward the sea floor without danger that the tubing will wrap about the risers when the hull weathervanes. The rig is mounted on the turret. Pipes (54) that extend from the rotatable part of the fluid swivel to fittings (55) on the hull (14), are supported on a gantry (80) that is fixed to the hull and having a gantry middle portion (106) that extends over the turret. The gantry middle portion extends higher than the top (88) of the rig.
摘要:
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.
