Patent ID: 8720578

Claim:
A method of deploying a subsea landing string, the subsea landing string having a helix that converges to a slot and interacts with a portion of a blowout preventer to orient the subsea landing string, comprising: lowering the subsea landing string through a riser and into the blowout preventer while a joint of the subsea landing string is in a retracted position where the helix is continuous; interacting the helix with a protrusion in the blowout preventer so that the subsea landing string is oriented, wherein upon fully lowering the joint the protrusion becomes located in the slot; extending the joint while the subsea landing string is landed so that the joint has an upper helix portion and a lower helix portion that is separated by a sealing surface, the sealing surface being adjacent to a blowout preventer pipe ram, wherein the joint is extended by applying tension to the subsea landing string.
