Patent number: 11448031Abstract: A wellhead load relief device for reducing riser system induced load effects on a subsea wellhead and a method of installing a subsea wellhead assembly onto a subsea wellhead using the wellhead load relief device. The wellhead load relief device includes: a receptacle for receiving well control equipment, wherein the receptacle has an open top to permit the well control equipment to be received in the receptacle; and an adjustable support mechanism for rigidly supporting well control equipment received in the receptacle. The adjustable support mechanism is located within the receptacle and the adjustable support mechanism has a lateral extent that is adjustable relative to the receptacle. The wellhead load relief device is for providing a load path for forces exerted on the well control equipment to the seabed without going via the subsea wellhead. A subsea wellhead assembly including the wellhead load relief device is also provided.Type: GrantFiled: November 27, 2018Date of Patent: September 20, 2022Assignee: EQUINOR ENERGY ASInventor: Per Osen

Patent number: 11346175Abstract: A connector for connecting two subsea well assembly components; wherein the connector is arranged such that it can be preloaded in both tension and compression concurrently. The connector includes a tension part which in use can be in tension and a compression part that in use can be in compression. The tension part has an adjustable length and/or the compression part has an adjustable length. There is also provided a subsea well assembly, that includes a first subsea well assembly component; and a second subsea well assembly component; wherein the first subsea well assembly component and the second subsea well assembly component are connected to each other to provide a well conduit therebetween. The first subsea well assembly component and the second subsea well assembly component are connected such that forces can be transmitted both in tension and compression between the two components without going through the well conduit.Type: GrantFiled: January 30, 2018Date of Patent: May 31, 2022Assignee: EQUINOR ENERGY ASInventors: Lorents Reinås, Harald Sigurd Nesse, Per Osen, Morten Sæther
