摘要： A vertical connection apparatus for connecting a pipeline to a subsea structure comprises a guide funnel for controlling the position of the pipeline relative to the subsea structure; a moveable barrier and a attachment region for a drive mechanism; the moveable barrier is operable between an open position in which the pipeline can pass through the guide funnel and a closed position in which the barrier prevent the end of the pipeline passing through the end of the guide funnel. A tool with a drive mechanism can be attached between the pipeline and guide funnel to manipulate the pipeline into a connectable position. A clamp connector secures the connection between the pipeline and subsea structure conduit.

摘要： A subsea wellbore system is disclosed in which a return fluid flows from a wellbore to the surface via an annulus between a drill string and a casing and then between the drill string and a riser, wherein the system includes a device configured to prevent flow of the return fluid flowing through the annulus between the drill string and the riser, and a bypass line configured to divert the flow of the return fluid from the annulus between the drill string and the riser to the surface.
