ABSTRACT:
A guidelineless reentry system for a subsea well uses a downward facing funnel. The well has a mandrel surrounded by a guide frame. A funnel and a mandrel connector are carried by the riser. Retracting rollers are mounted to the funnel. Once the riser lands on the guide frame, the rollers are extended to latch the funnel to the guide frame. The funnel is rotated along with the riser to orient the mandrel connector. The mandrel connector is lowered relative to the funnel into engagement with the mandrel.
