Abstract
An oil production system for producing oil at an offshore location comprises a floating storage vessel to receive the produced oil, the vessel having means for dynamic positioning and being connectable to a subsea well head by a riser and having means for separating the associated gas from the produced oil and employing the separated gas as fuel for the dynamic positioning. Re-entry of the subsea well is effected by providing the riser with means for effecting a simultaneous stab connection with the production bore and hydraulic control system lines without orientation.
