  • Patent number: 5002129
    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.

  • Patent number: 4886395
    Abstract: Method and apparatus for remotely connecting an offshore structure to an underwater pipeline using a remotely operated vehicle (ROV). The structure has a bell-mouthed bending guide at its base through which a winch line from the surface passes and is temporarily looped back and attached to an accessible place on the structure. Using the ROV and a surface tended messenger line the pull-in line is attached to a terminal assembly at the end of flexible pipe attached to the pipeline. The terminal assembly is pulled in horizontally to the guide, arcuately through the guide and then from the guide in general vertical alignment with a pipe end receiver assembly on the structure above the bending guide. At a location near the receiver assembly a towing head is removed from the terminal assembly and a second pull-in line is attached to the terminal assembly. The two pull-in lines are attached to opposite sides of the terminal for balanced pulling of the terminal assembly to connection with the receiver assembly.
