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

Patent number: 11293248Abstract: A wellhead assembly and a method of installing a wellhead assembly. The method includes providing a well casing; providing a wellhead support structure; locating and fixing the well casing in a hole in the waterbed, wherein when the well casing is located and fixed in the hole the wellhead support structure is located a distance above the waterbed so as to leave a gap between the surface of the waterbed and the underside of the wellhead support structure; and fixing the wellhead support structure onto the surface of a waterbed with a settable material by putting the settable material into the gap when in a non-solid state to provide a rigid connection between the waterbed and the underside of the wellhead support structure. The assembly is arranged so that bending moments applied to the wellhead assembly can be at least partially transferred to the waterbed via the wellhead support structure.Type: GrantFiled: October 28, 2018Date of Patent: April 5, 2022Assignee: EQUINOR ENERGY ASInventors: Morten Sæther, Asle Eide
