Abstract: Guide posts for any part of a sub-sea oil or gas installation can be installed in or removed from a guide foot solely by vertical movement. The guide post end has a surrounding locking sleeve capable of sliding axially relative to the guide post end and there is at least one locking mechanism formed of a ring or segments on the guide post and co-operating with at least one groove in the guide foot. Upward movement of the guide post end relative to the locking sleeve locks the mechanism, and upward movement of the locking sleeve relative to the guide post end unlocks it. The mechanism may be automatically reset by the unlocking action so that guide posts may be transferred underwater without being brought back to the surface, although damaged posts can always be retrieved if required. Tools for unlocking and removing the guide posts are also described, one of the tools being capable of dealing with bent guide posts.
