Publication number: 20240159117Abstract: Obstructing fluid plugs are removed from a base section of a riser, which base section extends between a receiving end connected to an upright section of the riser and an emitting end of the riser connected to a subsea template located on a seabed over a drill hole to a subterranean void into which fluid received via the riser is to be injected from the subsea template (120). The obstructing fluid plugs are removed either by injecting heated assisting from a storage container into an injection point in the base section and injecting heated assisting liquid from the vessel in the upright section of the riser, or a heating unit is controlled to heat the base section to a predetermined temperature, and thereafter maintain a temperature level here above or equal to the predetermined temperature.Type: ApplicationFiled: March 29, 2022Publication date: May 16, 2024Inventors: Ståle BRATTEBØ, Bjørgulf HAUKELIDSÆTER EIDESEN

Publication number: 20240141757Abstract: A subsea template is aimed at injecting fluid, e.g. carbon dioxide, for long term storage in a subterranean void. The subsea template has a base structure with a set of module receiving sections, each of which is configured to receive a respective utility module. A pipe interface receives at least one conduit transporting the fluid, for example from a vessel. The pipe interface forwards the fluid for injection into the subterranean void through a drill hole under the base structure via a valve tree installed in one of the module receiving sections. The other utility modules are configured to support the injection of the fluid into the subterranean void.Type: ApplicationFiled: March 2, 2022Publication date: May 2, 2024Inventors: Bjørgulf HAUKELIDSÆTER EIDESEN, Ståle BRATTEBØ

Publication number: 20240068332Abstract: A buoy accomplishes a fluid connection between a vessel on a water surface and a subsea template located on a seabed via at least one riser. A fluid is transported by the fluid connection from the vessel to the subsea template, and the fluid is injected from the subsea template (120) into a subterranean void via a drill hole. At least one valve in the buoy is controllable from an external site in response to commands so as to shut off the fluid connection from the vessel to the at least one riser.Type: ApplicationFiled: March 2, 2022Publication date: February 29, 2024Inventors: Bjørgulf HAUKELIDSÆTER EIDESEN, Ståle BRATTEBØ

Patent number: 11867322Abstract: A method of connecting a conduit to a subsea structure is provided. In the disclosed method, a tensioning member is provided on the conduit and attached to the conduit at two locations proximate a first end of the conduit. The tensioning member is used to maintain a curvature formed in the conduit between the two locations e.g. by deflecting a portion of the conduit. A first end of the conduit is engaged with a guide assembly provided adjacent to the subsea structure, and tension in the tensioning member is released to adjust the axial position of the first end of the conduit to enable direct connection between the conduit and the subsea structure. A method of disconnecting a conduit from a subsea structure, and a system for connecting a conduit to a subsea structure are also provided.Type: GrantFiled: May 20, 2020Date of Patent: January 9, 2024Assignee: Equinor Energy ASInventors: Håvar Ilstad, Erik Levold, Geir Endal, Kjell Einar Ellingsen, Bjørgulf Haukelidsæter Eidesen

Publication number: 20230407728Abstract: A method of installing a header pipe joint 1 at a subsea structure 5 is provided, comprising providing a header pipe joint 1 having at least one valve 2 installed therein and connecting the header pipe joint 1 inline of a spool 15 or pipeline 18 prior to lowering the header pipe joint 1 to the subsea structure 5. The header pipe joint 1 is then lowered to the subsea structure 5, and the valve 2 is connected to the subsea structure (e.g. a subsea production system of the subsea structure such as a xmas tree) with a connection bridge e.g. a choke bridge 14. This provides a fluidic connection between the subsea structure and the header pipe joint. The subsea structure 5 comprises a foundation, e.g. suction anchors 11, which provide support for both a wellhead and the header pipe joint. A subsea assembly comprising a subsea structure 5, header pipe joint 1 and connection bridge 14 is also provided.Type: ApplicationFiled: September 1, 2023Publication date: December 21, 2023Inventors: Kjell Einar Ellingsen, Bjørgulf Haukelidsæter Eidesen, Kristoffer Dahl

Publication number: 20200198735Abstract: A suction anchor and method of installing the suction anchor. The suction anchor including a suction chamber bounded by: a circumferential outer wall; an upper wall; and an internal housing wall. The internal housing defining a passage for receiving wellhead components that may be secured to the suction anchor. The suction chamber has a minor upper portion and a major lower portion. The minor upper portion having internal reinforcing members extending along the inside of the upper wall from the outer walls to the internal housing. The major portion is adapted to be embedded in a seabed and the minor portion is adapted to project from the seabed when the anchor is installed. The reinforcing members serve to reinforce the upper wall of the chamber against collapse and to rigidly support the internal housing to resist forces arising from bending moments applied to wellhead components received and secured therein.Type: ApplicationFiled: January 23, 2018Publication date: June 25, 2020Inventors: Lorents REINÅS, Kjell Einar ELLINGSEN, Asle EIDE, Bjørgulf Haukelidsæter EIDESEN, Harald Sigurd NESSE, Roger VANGSNES, Morten SÆTHER
