Norwegian oil service company Aker Solutions has signed a US$41 million contract with Petrobras to supply sulphate removal units for two FPSOs (Floating Production Storage and Offloading) platforms which will operate offshore Brazil.

The contract includes the supply of two sulphate removal systems with associated equipments to be installed on the topsides of the P-58 and P-62 FPSOs.

The sulphate removal technology delivers treated and de-sulphated seawater for injection into the hydrocarbon reservoir to maintain the pressure and control scaling and souring effects in the reservoir. High quality injection water devoid of sulphate and particles provides cost savings and improves the safety aspect in the handling of well streams.

"The Brazilian market is fast growing and there is a huge potential for the type of solutions we can offer through our highly experienced team," says Ronaldo Ribeiro, president of Aker Solutions' process systems business in Brazil.

The FPSO P-58 is expected to produce 180,000 barrels of oil per day and will operate in the North part of Parque das Baleias field. P-62 has equal capacity and will operate in module 4 of the Roncador field, both located in the Campos' Basin offshore Brazil. First oil is scheduled for 2014.

The contract party within Aker Solutions is Aker Solutions do Brasil Ltda. The project will be overseen by the Aker Solutions' process systems business.
