| 112 | Removable guide post | US447307 | 1989-12-07 | US5002129A | 1991-03-26 | Hans P. Hopper |
| 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. | ||||||

| 114 | Subsea guidepost latch mechanism and method for using | US247352 | 1988-09-21 | US4828035A | 1989-05-09 | Terry L. McInturff |
| A subsea guidepost latch mechanism which latches a guidepost to a guidepost-receptacle by means of an external snap ring on the guidepost and an internal groove in the guidepost-receptacle. The snap ring is held in the groove by a collet inside the snap ring which is forced outward by an inner mandrel in the guidepost when upward tension is placed on the mandrel by a guideline. The guidepost is released from the guidepost-receptacle by releasing tension on the guideline which allows the mandrel to drop, releasing outward force on the collet and the snap ring. This allows the snap ring to be pulled out of the guidepost-receptacle groove. | ||||||
| 115 | Connection device for a guide line of an undersea installation | US052235 | 1987-05-19 | US4799816A | 1989-01-24 | Alain Lechon; Yves Le Luel |
| A device is provided for connecting a guide line of an undersea installation. Inside the body of the connector is fixed an axial rod supporting a locking jacket with fingers carried by resilient blades. The rod ends in a centering nose having a cut out, whereas, above the centering nose a sliding ring is mounted on the rod and is held in position by a shearable pin. The guide post has a bore whose divergent section forms with a divergent face a housing for the locking fingers. When, for unlocking the connection, a tractive force is exerted on the connector body, the pin is sheared and the ring, by sliding, opens the passage for the fingers, which allows the connector to be released and raised. This connector requires no angular position with respect to the guide rod and makes any disconnecting tool superfluous. | ||||||
| 116 | Method and apparatus for remotely orienting a flowline for connection to a subsea structure | US31342 | 1987-03-26 | US4784523A | 1988-11-15 | Bill G. Louis; Ronald C. Mack |
