Abstract:
The invention relates to a mooring system comprising a first vessel (2) for containing hydrocarbons having at its bow and/or stem a transverse arm (7) and a fluid transfer means (18) comprising a duct connected to a tank (19) on the first vessel (2) and a coupling end for connecting to a second vessel (2), the second vessel being moored alongside the first vessel and being attached via at least one cable (11), extending from its bow in the length direction of the vessel, to a mooring end of the arm (7), which mooring end of the arm is substantially situated at or near a longitudinal centreline of the second vessel, wherein the arm, during use, is in a fixed position, a pulling force element being attached to the cable (11) for applying a pulling force on the cable (11) upon relative movement of the second vessel (3) with respect to the arm (7), the force element allowing a predetermined maximum displacement of the second vessel (3). The fluid transfer means comprises a frame (60) extending upwardly from a side of the first vessel, hingingly attached around a first hinge axis (61) that extends in the length direction of the vessel, a transverse arm (65) being hingingly connected to an upper end of the frame (60) around a second axis (66) that extends in the length direction of the vessel, a counterweight (67) being placed on one end of the transverse arm (65) and a vertical fluid duct (73) being supported from the transverse arm (65), the vertical duct having at its coupling end a connecting member for attaching to the second vessel (3) „ the vertical duct (73) being displaceable in the length direction of the vessels by a distance corresponding to the predetermined maximum displacement.
Abstract:
A method of supplying a first shipping port with liquid fuel for distribution or sale, the method comprising the steps of: filling the fuel tank(s) of a ship berthed at a second shipping port and destined for the first shipping port before voyaging onwards to a refuelling port for refuelling, which refuelling port may be the second shipping port, with an amount of liquid fuel in excess of that required for the ship to voyage to the first shipping port and, subsequently, to the refuelling port; and after voyaging to the first shipping port, transferring at least part of the excess amount of liquid fuel from the fuel tank(s) of the ship to a suitable storage means for distribution or sale.
Abstract:
A system for offloading LNG (liquified natural gas) from a tanker (26) in shallow waters, for regasing, or heating the offloaded LNG to produce gaseous hydrocarbons, or gas, for pressurizing the gas, and for flowing the gas to an onshore station (56), includes a structure that is fixed to the sea floor and projects above the sea surface and aids in mooring the tanker. In one system, the structure that is fixed to the sea floor is a largely cylindrical tower (12) with a mooring yoke (20) rotatably mounted on its upper end. A floating structure (14) such as a barge that weathervanes, has a bow end pivotally connected to a distal end of the yoke, so the barge is held close to the tower but can drift around the tower with changing winds, waves and currents. The tanker is moored to the tower so the barge and tanker form a combination that weathervanes as a combination. Regas and pressurizing equipment (32, 34) for heating an pressuring the LNG, and any crew quarters (36), are all located on the barge, so a low cost tower can be used. In another system, the structure is a breakwater (180).
Abstract:
The invention relates to a hydrocarbon transfer system comprising a first structure (8) carrying an articulated arm (4, 5, 61, 62), having at a free (64) end a first connector part (65), and a vessel (7) comprising a second connector part (70), wherein each connector part comprises a coupling member (72, 73). The coupling member (72)of the first connector part (65) supporting at least one fluid duct (110) on its exterior, which duct can be placed into sealing engagement with a fluid duct (111) on the vessel (7) along respective sealing faces, and a locking member for locking the coupling members together. The fluid duct on the vessel comprises a substantially horizontally directed first and second duct section (113, 116), the first duct section (113) being via a first swivel (112) with a vertical axis of rotation, connected to piping on the vesse l (7). The second duct section ( 116), being via a second swivel (115) having a substantially vertical axis of rotation, connected to the fluid duct (110)on the coupling member (72)of the first (65)connector part, the first and second duct sections being mutually connected via a third swivel (114) having a substantially vertical axis of rotation.
