Abstract: A poppet coupling comprising a male member comprising a cylindrical body part comprising a first outer diameter, and a cylindrical nose part having a second outer diameter, at an end which is to be inserted into a female member first; and the female member comprising an end opening for receiving the male member first, a primary seal for engaging the cylindrical body part, a cone-shaped opening, and a cylindrical opening, the cylindrical opening having a first inner diameter for receiving the cylindrical nose part.

Abstract: A sealing element that includes a hollow body of metallic material and first and second male sealing members formed at a respective end of the body. The respective male sealing member has an external spherical contact surface designed for mating with a corresponding internal conical contact surface of a female sealing member so as to form a fluid-tight seal between the male sealing member and the female sealing member when their contact surfaces are pressed against each other. Also, a coupling device and a valve device provided with the sealing element.

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: 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 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 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: 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 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 socket pipe joint includes a male part and a female part in telescopic overlapping position in the joint. An interlocking sleeve member is provided between the male and female parts. Locking elements including the interlocking sleeve member are provided to releasably lock the male part and female part to one another. A locking sleeve is positioned on the male part and extends from a position inside the female part to a position outside an end opening of the female part. A drive assembly is coupled to the locking sleeve on the outside of the joint and is operable to displace the locking sleeve axially between inner and outer positions. A positioning and interlocking element includes a pawl. By axial displacement of the locking sleeve, the pawl is displaced radially, positioning and interlocking the two pipe parts with simultaneous permanent compression of a seal between the pipe parts.
