Abstract: Connector (100) with locking components (107) about a peripheral section of the connector. The locking components extend in an axial direction engage with the connector (100) at a first end and engage with a connecting part (201) at an opposite locking end with a locking profile (109). A radial locking movement of the locking end is provided by an axial movement of an actuation sleeve (113). The locking components (107) are arranged to pivot in a substantially radial direction, about their section of engagement with the connector (100), into and out of a locking position. The connector (100) comprises guiding plates (111) between the locking components (107) in the area of their locking ends. The guiding plates exhibit protective faces (111a) that extend further radially inwards than the locking profile (109) of the locking components (107) when the latter are in the outwardly pivoted position.

Abstract: Telescoping riser arrangement forming part of a riser string (1) connecting a subsea well and a floating installation. The riser arrangement is adapted to be switched between a high pressure mode, in which an upper part of the riser assembly will move vertically with respect to the installation when the installation heaves, and a low pressure mode in which the upper part of the riser assembly will move vertically along with the installation when the installation heaves. In the low pressure mode, a low pressure inner sleeve (9) is adapted to reciprocate inside a high pressure outer sleeve (1a), the reciprocating heave path being above the position of the inner sleeve (9) in the high pressure mode. In the high pressure mode, the telescoping section of the low pressure inner sleeve (9) is enclosed within a high pressure compartment.

Abstract: A tension frame (2) for its application in a riser system for hydrocarbon exploration and production. The tension frame is (2) installed on a well control unit (5) atop at least one riser (9) in said riser system. The frame is adapted to receive a pressure control unit and hold it in line with the centre of the riser. The tension frame (2) houses at least two pre-installed pressure control equipment units (3, 4) of which one at a time is adapted to be hold at an active position, in which the unit is in line with the centre of the riser, and the other is adapted to be kept in a parked position within the frame.

Abstract: A coupling arrangement having external threads carried on a first pipe element. A second pipe element carries a radially movable locking member with external locking profiles, and a connection sleeve having internal threads that are threaded onto external threads and internal locking profiles that engage with the external locking profiles. The connection sleeve is moved in a first axial direction towards the first pipe element by rotation on the external threads while the internal locking profiles are in an intermediate engagement with the external locking profiles, until the movement is limited by abutting faces of the internal and external locking profiles. At least one of the abutting faces exhibits an inclination resulting in a pull of the connection sleeve towards an axial direction opposite of the first axial direction when the external locking profiles are moved radially.

Abstract: Coupling arrangement for connection of two pipe elements (11, 13), comprising external threads (17) on a first pipe element (13). A second pipe element (11) carries a radially movable locking member with external locking profiles (33). A connection sleeve (15) with internal threads (19) is threaded onto said external threads (17) and internal locking 11 profiles (35) are engaged with said external locking profiles (33).The connection sleeve (15) is moved in a first axial direction towards said first pipe element (13) by rotation on said external threads (17) while its internal profiles (35) are in an intermediate engagement with said external profiles (33), until said movement is limited by abutting faces (33a, 35a) of said internal and external profiles (33, 35), when possible axial clearances have been closed due to the4 first axial movement.
