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
