Abstract:
The invention relates to a device for removing solids from a fluid containment space, said device comprising a hood (11) arranged or intended to be arranged at a bottom surface of the fluid containment space, at least one inlet opening (14a) and at least one outlet opening (20a) being provided on a first side (15a) of the hood. The hood (11) is provided with means (21) for directing fluids through the respective outlet opening (20a) on said first side (15a) of the hood from the inner space (16) of the hood to the fluid containment space exterior of the hood in an essentially horizontal direction or in a direction towards the bottom surface of the fluid containment space. The invention also relates to a separator comprising such a device and a method for removing solids from a fluid containment space.
Abstract:
A method and a system for separating the phases of a multiphase fluid from one or more wells. The system comprises at least one first gravity separator (3-6) and at least one second gravity separator (3-6), and means for conducting the fluid from the well or wells to the first and second gravity separator(s) (3-6). The system comprises means (15-18, 41-44, 50-53, 54-57) for selectively conducting the fluid to the first and second gravity separators (3-6) either in parallel or in subsequent steps depending on the properties of the fluid and process conditions.
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. A contact element (10) is displaceably arranged in the contact housing (2b) of one of the coupling parts (1b) so as to be displaceable towards the contact member (3a) of the other coupling part (1a), when the contact housings (2a, 2b) are secured to each other, from a first position, in which no electric connection between the contact members (3a, 3b) is established by the contact element (10), and into a second position, in which the contact element (10) is establishing electric connection between the contact members.
Abstract:
The invention relates to a sealing element (20) comprising a hollow body (26) of metallic material and first and second male sealing members (21a, 21b) formed at a respective end of the body (26). The respective male sealing member (21a, 21b) has an external spherical contact surface (23a, 23b) 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. The invention also relates to a coupling device and a valve device provided with such a sealing element.
Abstract:
An inlet device (2) to a separator (1) comprising: a generally tubular outer wall (5) and a generally tubular inner wall (6), said outer and inner wall defining at least a part of a first annular path (7) between them, an inlet opening (8) through the outer wall (5) into the first annular path (7) for the passage of a fluid from the first annular path (7) into a second annular path (9). The device comprises at least one movable closing means (3) for at least partial closure of the fluid passage from said first annular path (7) into said second annular path (9).
Abstract:
Subsea wells are drilled and completed with an offshore floating platform (195) in a manner that allows simultaneous work on more than one well. A first well is drilled and casing. Then a tubing hanger (31) is run through a drilling riser and landed in the wellhead housing. Then, with the same floating platform, the drilling riser (201) is disconnected and moved to a second well. While performing operations on the second well, the operator lowers a production tree (39) from the floating platform on a lift line, and connects it to the first wellhead housing. An ROV assisted subsea plug removal tool (175) is used for plug removal and setting operations required through the production tree. Seabed separation is configured upstream of a production choke valve (275).

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:
The invention concerns a protective unit (1) for subsea installations. The unit includes walls with perforations or openings where these, in at least one of the walls of the unit (1) are designed as an integrated lattice structure (8).
Abstract:
The invention relates to a spool piece termination structure to be mounted to a spool piece so as to support a spool piece hub during the connection of the spool piece hub to a corresponding pipeline hub. The termination structure (5) comprises a clamping device (3) for clamping together said spool piece hub and pipeline hub, and a base frame (7) openly shaped downwards so as to allow the termination structure (5) to receive a pipeline end section provided with said pipeline hub by lowering the termination structure (5) downwards onto said pipeline end section. The invention also relates to a connection arrangement comprising such a spool piece termination structure (5) and a method for subsea connection of a pipeline to a spool piece.
