摘要： Nitrogen is produced above an offshore hydrocarbon reservoir (12) and injected into the reservoir, by a complex (40) mounted on a previously used vessel hull (16). The vessel weathervanes and the complex includes equipment that takes in ordinary air from a bow end (32) of the vessel, cools the air using sea water pumped into the equipment, and liquefies the oxygen component of air so pure nitrogen remains. The complex also includes injection equipment that heats and pressurizes the pure nitrogen to inject it into the reservoir. The complex is mounted above pipes (24) on the deck (22) of the vessel hull, on spacers (62) so mounting of equipment can be accomplished rapidly and without major alterations to the hull. A riser bundle (150) that extends from the hull to the sea floor, may include both a production riser (152) that carries crude hydrocarbons up to the vessel for storage in hull tanks (20), and an injection riser (160) that carries pressured nitrogen. The lower end of one of the risers is connected to a sea floor pipeline (162) that extends at least 100 meters away from the lower end of the other riser.
