ABSTRACT:
A guidelineless reentry system for a subsea well uses a downward facing funnel. A guide ring is mounted to the guide frame, which in turn is mounted around a mandrel on the well. A funnel and a mandrel connector are carried by the riser. Once the riser lands on the guide ring, latches are actuated to connect the funnel to the guide ring. Then, the mandrel connector is lowered relative to the funnel into engagement with the mandrel. A cam moves dogs outward to engage grooves of the mandrel to lock the mandrel connector to the mandrel.
