The new Petrobras-63 Floating Production Storage and Offloading (FPSO) vessel, NISA, featuring Wärtsilä 50DF dual-fuel engines, the first such ship to utilize gas engines to produce more than 100 MWe of power, has successfully completed all the required full 100% load tests. The tests were carried out at the Cosco shipyard in Dalian, China and the vessel will commence operations in Brazil’s offshore oil fields in 2013. The vessel is 342 metres in length, with a moulded breadth of 57.36 metres and a moulded depth of 28.5 metres. It was converted from a 320 000-dwt ULCC, built in 1983. NISA has a daily production capacity of 140,000 barrels of oil (bopd) and 35 million cubic metres of gas. The storage capacity by design is 1.4 million barrels and the operating depth is 1,200 metres. Classified by ABS, NISA is equipped with a spread mooring system and is designed to work for 25 years successively without docking work.
