Rolls-Royce has unveiled yet another contract win, in this case with Petrobras, a deep and ultra-deep water oil and gas exploration and production company. The $138m, five-year services contract will see it support Petrorbras's oil production activities offshore Brazil by supplying maintenance and repair services to support 15 Rolls-Royce RB211-G62 industrial gas turbine power generation units.The long-term service agreement contract has a potential value of up to $220m over its five-year renewal period.The units are installed on four Petrobras oil platforms, which together can produce more than 500,000 barrels of oil per day (equal to 25% of Brazil's entire output), operating in the petroleum-rich Campos Basin. Andrew Heath, Rolls-Royce President of Energy, said: "Rolls-Royce technology is at the heart of Brazil's thriving energy infrastructure. This services contract renewal reflects the excellent working relationship we have developed on this project with Petrobras over the past five years."NR
