Abstract: The invention relates to a connection system for connecting lines requiring angular orientation to land based or subsea production structures, the system including a connector (200) and a connector receiver (100) secured to a production structure surface (110) adapted to receive the connector. The connector receiver includes guide slots (108) for receiving guide keys (208) of the connector. The guide slots serve to guide the connector into angular and axial alignment with the connector receiver and to provide a soft landing preventing damage to the connecting ends.

Abstract: The present invention relates to a locking mechanism or tool adapted for connection to a remotely operated vehicle and adapted for at least one of the group consisting of connection and disconnection of two plates. The present invention also concerns a system adapted for at least one of the group consisting of connection and disconnection of two plates, where the system comprises said locking mechanism or tool.

Abstract: The present invention relates to hydrocarbon well fluid manifold module (1) with a manifold module housing (9) having a transversal bore terminating in a longitudinal bore (3) in fluid connection with the transversal bore (6). One or more cut off valves are located (7) in the transversal bore (6). The longitudinal bore (3) extend through the module housing (9) and form a first flow port (11) and a second flow port (12) aligned with the first flow port (11). Plane, connecting surfaces surround the two flow ports (11,12). The two flow ports and connecting surfaces are identical. The first connecting surface (13) and the second connecting surface (14) are adapted to be connected to at least one further similar manifold module (20). The invention also concerns a manifold for a hydrocarbon well assembled of such modules.

Abstract: A horizontal connection arrangement for subsea connection of a first hub arranged on a first subsea module to a second hub arranged on a second subsea module. The first hub is fixed to a first holding unit and the second hub is fixed to a second holding unit. A sliding unit is slidably mounted to the first holding unit so as to be horizontally moveable in relation to the first holding unit. A connector for connecting and securing the first hub to the second hub is mounted to the sliding unit and horizontally moveable together with the sliding unit between a retracted position, in which an outer end of the first hub projects beyond a front side of the connector, and an advanced position, in which the outer end of the first hub is received inside the connector.

Abstract: A pipeline termination arrangement to be mounted to a pipeline end section to support a pipeline hub of the pipeline end section during and after a subsea connection of the pipeline hub to a spool piece hub fixed to a spool piece termination structure is provided. The pipeline termination arrangement includes a landing structure for supporting the spool piece termination structure; a connection porch fixed to the landing structure; and a support structure which is fixed to the pipeline end section and provided with a guide frame. The guide frame slidably supports the landing structure so as to allow the landing structure and the connection porch to slide along the guide frame from a first position, in which the connection porch is located in front of and at a distance from the pipeline hub, to a second position, in which the connection porch is in contact with the pipeline hub.

Abstract: A subsea wellhead assembly having a tubing hanger set in a tubing hanger spool and a ring with axial passages set in an upper end of the tubing hanger. The wellhead assembly includes a production tree that lands on the tubing hanger spool. Tubing extends from the axial passages in the ring through axial bores provided in a sidewall of the tubing hanger. When landed, a lower end of the production tree engages an upper surface of the ring causing the ring to rotate and align its axial passages with axial passages in the production tree. The respective lower and upper surfaces of the tree and ring are strategically castellated to orient the passages.

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: 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.
