Title: Telescoping orientation joint

Abstract: An orientation joint for a subsea landing string equipped to maintain both unitary and telescoping configurations. For example, the joint may maintain a unitary configuration to provide continuous orientation definition while lowering a landing string within a blowout preventer (BOP). Additionally, the orientation joint may be configured to telescope and provide an appropriately sized uniform outer diameter surface to enable a sealing engagement with an aligned ram of the BOP.
