Abstract:
A coupling unit device for unloading of a ship, where the coupling unit comprises a hull and is arranged to be connected to the ship by means of a connecting element wherein the coupling unit is provided with an evaporator for liquefied natural gas (LNG) and the required pipe elements for transporting liquefied natural gas from the ship to the evaporator, as well as the required pipe elements for transporting the evaporated gas from the evaporator to a pipe for onward transport. The coupling unit is free-floating and is arranged to manoeuver itself to the ship during the connection and disconnection from the ship by means of its own propulsion machinery.
Abstract:
A device for loading or unloading a ship (6), wherein a loading pipe or a loading hose (12) is connected to the ship (6) via a floating, self-motored coupling unit (1) designed to be moored to the ship (6), preferably near the loading manifold (18) of the ship (6). The coupling unit (1) has sufficient propulsive capacity to maintain the ship’s (6) position during the loading operation.
Abstract:
A method of dynamic positioning of a vessel (16, 32), wherein a positioning system controls at least one positioning machinery (18), and where two or more buoys (1), each comprising at least one positioning machinery (18), are coupled to the vessel (16, 32).
Abstract:
Turret for connection of a buoy (1) to a vessel, where the buoy (2) has a shape substantially like a circular cylinder and being adapted to be connected with a vertically arranged sleeve (2) in the vessel and to be locked to the sleeve (2) by means of locking devices (3) and that the sleeve (2) is rotatably supported in bearings (4) arranged in the vessel, and that lines (5) for transfer of media etc. between the vessel and the seabed, extend centrically through the buoy (1).
Abstract:
A method for connecting two floating units (1) and (2), the lower part (2) being equipped with position keeping means such as a mooring system or thrusters and being capable of transferring position keeping forces according to the environmental loads acting on the upper unit (1) by use of friction pads (5, 6), enabled by establishing a vertical contact force between the two units sufficient to be able to transfer the horizontal loads by use of friction between the friction pads (5, 6) and the upper unit (1).
