  • Patent number: 11149534
    Abstract: A method of processing a fluid produced from a well, the produced fluid being a high pressure fluid, the method comprising: reducing the pressure of the fluid to a reduced pressure such that a gas phase and a liquid phase are formed; separating the gas phase from the liquid phase thus forming a gas product and a liquid product; and storing the liquid product in a storage tank at a pressure such that the liquid product remains in a stable liquid phase during storage, wherein the reduced pressure is greater than atmospheric pressure.

  • Publication number: 20190360319
    Abstract: An offshore hydrocarbon processing facility (2) comprises an offshore floating structure (8) and a submerged floating riser deck (10). The submerged floating riser deck is operatively connected to a subsea hydrocarbon riser (12). Hydrocarbon processing equipment (26) is disposed on the submerged floating riser deck. The offshore floating structure (8) may be connected to the submerged floating riser deck (10) using a riser (16) that can be disconnected if there is inclement weather.

  • Patent number: 7448404
    Abstract: Seabed located storage for crude oil or other fluid, distinguished in that it is comprising a storage section in form of an oil and waterproof cloth formed as a flexible balloon that can be filled with, store and emptied for a storage fluid, a structure section formed as an external casing over the storage section, which structure section is closed in the upper part such that an upward close volume of size at least corresponding to the volume of the storage section is formed, but with openings to the surroundings in the lower part, an anchoring section formed as a substructure between the structure section and the seabed, with means for anchoring to or stable placement on the seabed, and a transfer section comprising pipes and valves for loading and unloading of a storage fluid, arranged in substance exterior to the upper part of the storage.

  • Publication number: 20070267061
    Abstract: The present invention discloses a bellows (5) for use in a fluid container (1), wherein the fluid container (1) is arranged so as to contain a first fluid comprising a liquid phase (7?) and a gas phase (7?), and wherein the bellows (5) is arranged so as to separate said first fluid (7?, 7?) from a second fluid (9) transported into the bellows (5) from the exterior of the container (1). In a preferred embodiment, the bellows (5), when filled, is arranged so as to occupy a volume portion of the second fluid (9) and, when emptied, is arranged so as to contain substantially no volume portion of said second fluid (9). The invention also concerns a method related to transport and/or discharging of a container (1), wherein the volume of said first fluid (7?, I1?) of the container (1) is replaced by a second fluid (9) filled into the bellows (5).

  • Publication number: 20070014636
    Abstract: There is provided a system comprising an assembly for storage or transport of compressed gas on a floating structure (1), wherein the assem+y (3) comprises a plurality of separate, parallel, laying pipes (4) which are closed at both ends and are supported discretely or continuously by a supporting structure (5). The pipes (4) are releaseably attached to the supporting structure (5) only at one end thereof, where the pipes are coupled to a manifold system (˜) for filling or emptying of the pipes, and the supporting structure (5) is arranged to allow unobstructed longitudinal guiding of the pipes (4) in the storage assembly (3), so that the pipes individually or in groups can be introduced to or removed from their operating position in the storage assem+y via openings at the ends of the assem+y located oppositely to said one end.
