The FPSOs operate in the pre-salt Iracema cluster areas in the Santos basin, off the coast of Rio de Janeiro, Brazil.

Petrobras-led consortium Tupi chose Keppel FELS Brasil for the fabrication and integration of the vessels.

With the contract, which includes pump packages for seawater lift, water injection and auxiliary services, Sulzer will be supplying eight FPSOs currently under construction for Petrobras and more than 1,300 pumps in service for the company’s offshore operations in Brazil.

Sulzer said the water injection pump packages contain API 610 BB5 pump models driven by 5.5MW electric motors, while the seawater lift pump packages comprise vertical pumps run by 960kW submersible electric motors.

Other pumps are used for various auxiliary services, such as cooling water circulation, hot water circulation and water injection pump boosting.

Scheduled for delivery in 2014, the pump packages will be built at Sulzer’s manufacturing and distribution center in Jundiaí, São Paulo.
