The systems may further include an inner drilling riser tie-back connector (“ITBC”) coupled to an inner riser and having an outer body and an inner body. The inner body is at least partially disposed within the outer body, and the inner body is translatable along a longitudinal axis of the ITBC between a first unlocked position and a second locked position.
