发明名称 Orienting a subsea tubing hanger assembly
摘要 An apparatus includes an engagement device to be disposed on a landing string. The engagement device includes a retracted state to allow the apparatus to be run inside a riser and an expanded state to engage the riser to secure the apparatus to the riser. The apparatus further includes an actuator assembly to be disposed on the landing string.

主权项 1. A method comprising: deploying a landing string inside a riser beneath a sea surface to land a tubing hanger assembly in a wellhead of a subsea well, the landing string comprising a rotator assembly connected to the landing string above the tubing hanger assembly; rotationally securing a first portion of the rotator assembly to an inner surface of the riser; and orienting the tubing hanger assembly relative to the wellhead by rotating a second portion of the rotator assembly, the landing string, and the tubing hanger assembly relative to the first portion of the rotator assembly, the riser, and the wellhead by using the rotator assembly while the first portion of the rotator assembly is rotationally secured to the riser.
