Publication number: 20080271896Abstract: The present invention relates to a heave compensator for a riser, particularly a working riser (9), comprising a telescopic connection (10) with a first chamber (60) which is in fluid connection with the interior of the riser and a second chamber (62) which is connected with a source of pressure fluid. By varying the pressure in the second chamber in response to the movements of the platform, the telescopic connection can be arranged to move in correspondence with the platform's movements, thereby permitting access to the riser during working operations.Type: ApplicationFiled: May 23, 2005Publication date: November 6, 2008Applicant: FMC Kongsberg Subsea ASInventors: Olav Inderberg, Hans-Paul Carlsen, Anthony D.

Patent number: 6843321Abstract: A device for intervention of a subsea oil and/or gas well by means of a tool (8) suspended by a cable (9), fed from or withdrawn to a vessel (1) and driven by a drive mechanism (12) located on the vessel. The device comprises a lubricator (5) having a tool housing for the insertion of the tool into the well, and a stuffing box (40) sealing around the cable after the tool is inserted into the well. According to the invention an injector which drives the cable in the well is located on the lubricator, and is controllable independently of the drive mechanism for the cable located on the vessel. The drive mechanism and the injector may be synchronized in a manner, among others, providing that the cable is hanging in a predetermined arc during the intervention, whereby the vessel may be moved from the well. Moreover, the invention relates to a method and a cable used together with the device.Type: GrantFiled: February 20, 2001Date of Patent: January 18, 2005Assignee: FMC Kongsberg Subsea ASInventor: Hans-Paul Carlsen

Patent number: 6739570Abstract: A safety valve of the type where two valve elements (4) in a bore (3) can be moved towards each other for closing a flow path (2). Each valve element comprises two parts (10, 20), each of which is connected to an actuator (5, 6), thus enabling them to be moved independently of each other.Type: GrantFiled: December 4, 2001Date of Patent: May 25, 2004Assignee: FMC Kongsberg Subsea ASInventor: Hans-Paul Carlsen

Patent number: 6733203Abstract: A clamping device for a wire or cable (2), the end of which has to be attached in a housing (10) includes two clamping bodies (7, 8) with interacting conical surfaces. One clamping body (7) is arranged for receiving and passing through the cable (2), which has to be secured. The second clamping body (8) is arranged to exert pressure against the first clamping body for frictional securing of the cable. The clamping bodies are arranged in such a manner that when the tension in the cable increases the clamping bodies enclose the cable more tightly. The invention is particularly suitable for tools that have to be lowered into a well by the cable.Type: GrantFiled: December 14, 2001Date of Patent: May 11, 2004Assignee: FMC Kongsberg Subsea ASInventors: Hans-Paul Carlsen, Gunnar Herø

Patent number: 6112815Abstract: Inflow regulation device for a production pipe for production of oil or gas from an oil- and/or gas reservoir (9), where the production pipe comprises a lower drainage pipe with drainage pipe sections (5) with one or more drainage pipe elements (2; 2a, 2b) having opening(s) (3; 3a, 3b) for inflow of oil and/or gas to an inner space (8) of the drainage pipe section. The inflow may be regulated by a movable sleeve (1) that abuts one adjacent side surface of the drainage pipe section (2; 2a, 2b) and where the sleeve is provided with a portion(s) (6) being able to cover/uncover the opening(s) in the drainage pipe element. The sleeve further comprises helical spurs/recesses (14, 15) that in conjunction with one adjacent abutting surface (18, 21) of the drainage pipe element (2; 2a, 2b) forms channels (16, 17) that may connect the reservoir (9) with the inner space (8) of the drainage pipe. The helical spurs/recesses (14, 15) may be constituted by one or more pair(s) of left- and/or right-oriented spurs/recesses.Type: GrantFiled: August 5, 1998Date of Patent: September 5, 2000Assignee: Altinex ASInventors: Einar B.o slashed.e, Olav Sveinung Haugerud, Hans-Paul Carlsen

Patent number: 5997045Abstract: Pipe joint for joining two pipe end sections (1, 1'), the pipes support in their walls one or more bores (7) and/or lines or conduits (8) for hydraulic or electrical energy transfer. The pipe joint comprises a pipe union (3) with internal threads (13, 13'), one section thereof is threaded to the right, and another to the left. These threads correspond respectively with similar external threads (6, 6') at the pipe ends. A joining part (2) is arranged between the two pipe ends, and serves to mutually center and lock the pipe end sections. In the joining part (2) there is arranged joining sleeves (4) for each bore (7) or line (8), to obtain a tight joint between these.Type: GrantFiled: April 21, 1997Date of Patent: December 7, 1999Assignee: Norsk Hydro ASAInventors: Einar B.o slashed.e, Hans-Paul Carlsen, Stig Holgersen, Olay Sveinung Haugerud

Patent number: 5881807Abstract: An injector (1) for injecting a traceable material into an oil and/or gas reservoir is lowered down into a bore hole that is in communication with the reservoir. An electro-hydraulic system is activated to inject a traceable material stored in a container into the reservoir. The injector is provided with a gland plate (7) that seals a space between the injector and the wall of the bore hole (16) in a manner that prevents traceable material from being distributed in the bore hole, but secures direct injection of the material into the reservoir. The injector is adapted to be positioned at a specific depth level in the bore hole, and to be cleaned by pressurized liquid after the injection operation is completed.Type: GrantFiled: March 6, 1997Date of Patent: March 16, 1999Assignee: Altinex ASInventors: Einar B.o slashed.e, Hans Paul Carlsen, Stig Holgersen, Olav Sveinung Haugerud
