Nganhurra is the 900,000 bbls FPSO with very unique design which enables her to travel at 12 knots, at designed draft without tug assistance. A FPSO with propulsion function is very rare and there has been only one new building FPSO with the function, whose name is Sea Rose (940,000 bbls FPSO) built by Samsung. Therefore, Nganhurra is reportedly only the world second FPSO with propulsion function. The Enfield field, where Nganhurra is deployed, is located in the Carnarvon Basin, approximately 40 km offshore from North West Cape, Western Australia. The field development concept comprises the use of subsea wells and flowlines to support a single Floating Production Storage and Offloading (FPSO) facility to receive reservoir fluids (oil, water and gas). Nganhurra is moored on location with a water depth range from 350 to 700m, using a disconnectable single point mooring system. The FPSO will disconnect the single point mooring system and evacuate when a very strong cyclone comes. The FPSO's Topside processes the produced fluids into oil, gas and produced water streams. The stabilized crude oil will then be stored in the cargo tanks of the FPSO and offloaded to tandem-moored trading tankers via a floatShip Name Ship Type Ship Owner Ship Builder Otello Pure Car/Truck Carrier Wallenius Marine AB Daewoo Shipbuilding
ing flexible hose, and produced water will be further treated using hydrocyclones prior to disposal overboard. Twelve (12) deep-well cargo pumps with 700 cu. m./hr. are installed to transfer 550,000 bbls of cargo oil within 24 hours.
