Abstract: A sealing element including a tube-shaped body of metallic material and first and second male sealing members arranged at a respective end of the body. At least two intermediate members are arranged in series in the body between the first and second male sealing members. Each one of the intermediate members is compressible so as to be capable to store elastic energy when the body is subjected to axial compression and includes a protuberance arranged in the body and extending around the center axis of the body. A coupling device provided with such a sealing element.

Abstract: The invention concerns a subsea separation apparatus for processing crude oil comprising a separator module (3) with a separator tank 3a). The separator tank (3a) surrounds an opening (42) going there through, placed substantially in the geometrical centre of the separator tank (3a). The opening (42) is accessible for other processing equipment for the crude oil. Furthermore the separator tank (3a) may be substantially symmetrically placed on a well head (4b) and the separator module (3) may be substantially concentrically placed on the well head (4b).

Abstract: An electrical switching device including at least one ingoing conductor at least a first and a second outgoing conductor, and an arrangement for connecting and disconnecting the conductors by means of an axial movement. The arrangement includes an axially movable element, which is movable between a first and a second position. The device is arranged such that when the axially movable element is in the first position, the ingoing conductor and the first outgoing conductor are electrically connected, and the ingoing conductor and the second outgoing conductor (3) are disconnected. When the axially movable element is in the second position, the ingoing conductor and the first outgoing conductor are disconnected, and the ingoing conductor and the second outgoing conductor are electrically connected.

Abstract: The invention relates to a coupling device including a coupling part provided with a coupling member and having an internal bore extending through the coupling part and its coupling member, wherein the coupling part is provided with a valve, which includes a valve body displaceably arranged inside the internal bore and a spring member acting on the valve body, the valve body being displaceable against the action of the spring member from a first position to a second position. The valve includes a housing fixed inside the internal bore, the housing being provided with a cavity accommodating the spring member and a part of the valve body. The cavity is in fluid communication with an orifice at the end of the valve facing the free end of the coupling member so as to allow the cavity to be in fluid communication with the surroundings via the orifice when the coupling member is out of engagement with a corresponding coupling member.

Abstract: A subsea system for separating a multiphase fluid emanating from one or more subsea wells, comprising a foundation structure (1) secured to the seabed, a header piping module (2) adapted to be mounted to the foundation structure (1), a separator piping module (3) adapted to be removably mounted to the header piping module (2), and one or several insert modules (4-8), each of which comprising a processing appliance of the subsea system and being adapted to be removably mounted to the separator piping module (3).

Abstract: A subsea system for processing a fluid emanating from one or more subsea wells, comprising a fluid processing circuit and a base module (3) provided with at least one receiver (40) for receiving an insert module (4-8) comprising an appliance that forms part of the fluid processing circuit. The receiver (40) comprises a cavity (30) for accommodating the insert module (4-8). The insert module (4-8) is provided with a flange (31), which is adapted to bear on a corresponding flange (32) of the receiver (40) when the insert module (4-8) is mounted therein, a watertight seal (33) being arranged between said flanges (31, 32) so as to seal the space between the receiver (40) and the part of the insert module (4-8) received therein from the surrounding sea water.

Abstract: A coupling arrangement for use in subsea electrical power distribution comprising a first coupling part (1a), which is provided with a first contact member (3a) arranged in a first contact housing (2a) and an attachment (4a) for a first power conduit, and a second coupling part (1b), which is provided with a second contact member (3b) arranged in a second contact housing (2b) and an attachment (4b) for a second power conduit to be connected to the first power conduit by means of the coupling arrangement.

Abstract: The invention relates to a system for intercoupling of two pipeline which are located in a subsea position. A second pipeline (12) is preinstalled on a bottom based template or frame (10), and a first pipeline (2) is initially freely positioned, located in a smaller or larger distance from said second pipeline. Equipment is available for transport of said first pipeline to the bottom frame with said second pipeline, and equipment for positioning, holding and coupling of the pipelines, such that a pressure resistant, strong coupling is provided between the same. One aspect of the invention relates to a ring-shaped, open seat (18) mounted on the bottom frame (10) at a certain space in front of a terminator (14) on the end of the second pipeline (12) mounted on the bottom frame (10).

Abstract: The invention relates to a system for pull-in and interconnection of two pipelines in subsea position, whereof one first pipeline initially is freely suspended, while one second pipeline for instance is mounted on a bottom based manifold frame. The end section on the first pipeline is provided with a socket-like termination with a front end, which is provided with means (17) for coupling of the terminator (8) to complementary pipe coupling means (29) on the second pipeline (19). The terminator (8) is provided with a laterally directed, longitudinally shaped anchor element (10), and the manifold frame (22) is provided with receiving means (24) for receipt and fixation of the anchor element (10).
