Rolls-Royce today announced a new order from the Brazilian state oil company, Petrobras, for an additional four gas turbine power generation packages valued at $73 million for use on a new offshore platform.

This brings the number of Rolls-Royce gas turbine generator sets for Petrobras offshore projects to 27 since 2001, with a total value of more than $300 million.

The new order is for RB211-powered generating set packages for the
$1.2 billion P-56 semi-submersible platform, which is part of the development of the Marlim Sul field, located off the coast of Rio de Janeiro in the Campos Basin, Brazil’s most abundant oil production area.

Tom Curley, president of the Rolls-Royce energy business, said: “We are once again pleased to be chosen by Petrobras for these latest offshore units. We are proud of the relationship that has continued to strengthen between Petrobras and Rolls-Royce over the past several years, and we look forward to continuing to play an integral role in Brazil’s oil and gas production activities.”

Four RB211 dual-fuel generating sets will be installed in two modules and will provide complete electrical power for the P-56 platform. Once situated, the platform will be located 124km off the coast and will eventually be connected to 22 different wellheads at a depth of 1,700m.

Out of the 22 wellheads, 11 of them will be oil and gas producers, with the remaining 11 used to inject water to increase the production flow.

The platform will weigh 46,500t, measuring 125m long,110m wide, and 54m tall. It is designed to operate for 25 years and will be capable of processing and treating 170,000 barrels of liquids and producing 100,000 barrels of oil, six million cubic meters of natural gas, and injecting 45,000m³ of water per day into the reservoir.

The gas turbine generating sets will be packaged by Rolls-Royce at its plant in Mount Vernon, Ohio, with the RB211 gas turbine engines being manufactured at the Rolls-Royce facility in Montreal, Canada.
