vertical connection apparatus for connecting a pipeline to a subsea structure

摘要

The invention relates to a vertical connection apparatus for connecting a pipeline 12 to a conduit 14 on a subsea structure and comprises a guide funnel 22 for controlling the position of the pipeline relative to the subsea structure; a moveable barrier 26 and an attachment region 32 for a drive mechanism 36. The moveable barrier is preferably a sliding rod operable between an open position in which the pipeline can pass through the guide funnel and a closed position in which the barrier prevents the end of the pipeline 12 passing through the end of the guide funnel. A tool 36 such as a hydraulic cylinder can be attached between the pipeline and guide funnel to manipulate the pipeline into a connectable position. A clamp connector 18 secures the connection between the pipeline and subsea structure conduit. Later embodiments relate to a system and method for positioning a pipeline using said apparatus.
