摘要： Subsea unit for offshore production of oil or gas, comprising one or more wellheads with associated christmas trees (7-9, 17-19, 22, 27-29) provided on or at a bottom frame (template) (5, 15, 25). On or at the template (5, 15, 25) there is mounted a swivel device (10, 20, 30) having fluid connection (10C) to the christmas tree or trees and being provided with connection members (44A, 43A) for risers (44) and an umbilical or control cable (53) from a production vessel (3) at the sea surface (2).

摘要： Swivel assembly for installation at a well for subsea production of oil or gas, and adapted to be connected to a production vessel at the sea surface, comprising a main or fluid swivel having at least two paths (21, 22) and an electric/hydraulic auxiliary swivel (28) for signal communication and power transfer. The fluid swivel is provided with a rotatable swivel housing (24) at the top of a stationary christmas tree (50), preferably comprising a small number of valves, such as a production master valve (51) and an annulus master valve (52). Said paths (21, 22) are through-running vertically in the central core member (25) of the fluid swivel so as to make possible well intervention from the upper side of the fluid swivel.

摘要： A rotating connector comprising a swivel device (5, 6) having a number of fluid courses (16) for interconnection between a buoy (1) and a pipe system on a floating vessel for production of hydrocarbons, wherein the swivel device comprises a female member (5) and a male member (6) which may be introduced axially into or withdrawn from each other, the female member (5) being permanently fixed to a bottom-anchored centre member of the buoy. One of the fluid courses is arranged for transferring liquefied natural gas (LNG) between the vessel and a transfer line (13) through the buoy, and for this purpose is thermally and physically separated from the other courses (16). The LNG course is a pipe course or an annular course (43) in a separate unit (40) placed centrally within or surrounding the male swivel member (6), the unit comprising an insulating cofferdam means having an annulus (45) for insulation between the LNG course (43) and the male swivel member (6), and an additional annulus (47) for insulation between the LNG course (43) and the female swivel member (5) when the unit (40) surrounds the male swivel member (6). The annulus or annuluses (45, 47) is/are open towards the surroundings via a peripheral annular opening (52, 53) which in operation is sealed against the surroundings by sealing means (54, 55) for control of a possible LNG leakage via LNG seals (51) between the LNG course (43) and its connection with the transfer line through the buoy.
