Abstract
A string of conduit extending from a subsea wellhead assembly to a surface wellhead assembly on a platform has a plurality of grooved profiles on an upper portion of the conduit. Each profile is spaced axially from another of the grooved profiles. After a lower end of the conduit is secured to the subsea wellhead assembly, the operator pulls on the conduit to apply a selected tension to the conduit. The operator attaches a support ring to the profile that was closest to and above a load shoulder in the surface wellhead assembly when the desired tension was reached. After landing the support ring on the load shoulder, the operator may cut off any excess portion of the upper portion of the conduit located above the support ring. A seal ring is set between the upper portion of the conduit and the surface wellhead housing.
