Abstract
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.
