Abstract: A system to pressurize barrier fluid of a submersible installation to provide a differential pressure between the ambient pressure surrounding the submersible installation and the pressure of the barrier fluid internally in the submersible installation during submersion of the system, wherein the differential pressure fits within a predetermined differential pressure range. The system comprises a pre-charge arrangement and a pressure intensifier which is adapted to start working at a start-up pressure. The pre-charge arrangement is adapted, during submerging of the system, to provide a differential pressure within the predetermined differential pressure range until the ambient pressure equals the start up pressure of the pressure intensifier, while the pressure intensifier is adapted to provide a differential pressure within the predetermined differential pressure range when the ambient pressure equals the start-up pressure of the pressure intensifier during further submersion of the system.

Abstract: A fluid pump system comprises an electrical drive unit and a rotary pump comprising a rotatable shaft and a drive element formed from a number of impellers attached to the shaft for causing flow within a process fluid. The electrical drive unit comprises an electrical stator and an electrical rotor attached to the shaft via a coupling, the electrical stator being disposed adjacent to the electrical rotor. The electrical stator is disposed within a first casing and the rotary pump and the electrical rotor are disposed within a second casing. The first casing contains a first fluid and the second casing contains a second fluid.

Abstract: The present invention regards a flexible joint for transfer of especially a cryogenic fluid, comprising a first element (3) and a second element (4). The first element (3) comprising an internal, partly curved surface (6), the second element (4) comprising a corresponding outer partly curved surface (8) with at least a sealing element (12,12?) between the curved surfaces (6,8). The first element (3) comprises a first connection part (9) and the second element comprises a second connection part (10) connectable to the first connection part (9) with a flexible part (11, 11?) between the connection of the two connectable parts (9,10) and the sealing element (12). Thereby it is formed a void (16) which may be pressurized with an inert gas at a pressure equal to or higher than the pressure of the fluid to be transferred through the joint.

Abstract: The present invention regards a system for transferal of at least one cryogenic fluid between to objects. At least one transfer pipe extending from the installation extends into a receiving room in the vessel, the transfer pipe being connectable with piping on the vessel through connection means in the receiving room. According to the invention the receiving room is closable, the connection means, and or at least a part of the construction forming the receiving room and or other elements in the receiving room comprises means to withstand eventual leakage of the cryogenic fluid and the system also comprises means for evacuating the receiving room for eventual spilled fluid. The invention also regards a flange for use in the system.

Abstract: A system for transfer of liquefied natural gas (LNG) between two vessels (1, 2). The system comprises a coupling head (7) mounted at one end of a flexible pipe means (4) and arranged for attachment on a platform (19) at one end of one vessel (1) when it is not in use, and a connection unit (8) mounted at one end of the other vessel (2) and comprising a pull-in funnel (50) shaped for guided pull-in of the coupling head (7) to a locking position in which the pipe means (4) can be connected to transfer pipes (56) on the other vessel (2) via a valve means (31) arranged in the coupling head. The coupling head (7) is provided with a guide means (40) and is connected to at least one pull-in wire (42) for guided pull-in of the coupling head (7) into the connection unit (8) by a winch means (66) an the other vessel (2).

Abstract: A system for supplying cooling water to a process on board a floating vessel for the production of hydrocarbons, wherein the vessel (1) is anchored by means of a bottom-anchored turning unit (20) mounted in a receiving space (7) in the hull (34) of the vessel and allowing turning of the vessel (1) about the turning unit, and wherein the turning unit (20) supports a swivel unit (24) for the transfer of hydrocarbons from production risers (28) extending between the seabed and the turning unit (20), the system comprising a conduit means (30) depending from the vessel (1) to a depth for taking in cooled sea water, and a pump means (44) for pumping of the sea water from the conduit to a place of use for the process.

Abstract: This invention concerns a unitary system for export of liquid natural gas (LNG) from a floating production vessel (FPSO vessel) (1), with the new and inventive consists of the combination of the following points: an LNG buffer tank in the FPSO vessel, with buffer storage capacity for temporary storage of the continuous produced LNG during an LNG tank vessel's absence, a mooring device arranged for short separation moorage between the FPSO vessel's stem and an LNG tank vessel's bow, a cryogenic transfer device arranged between the FPSO vessel's stem and an LNG tank vessel's bow, comprising a flexible LNG pipe and arranged for consecutive transfer of produced LNG; at least one or several LNG storage tanks in an LNG tank vessel, arranged for continuous filling via the cryogenic transfer device until the desired degree of filling of the LNG tank vessel is achieved.
