The Petrojarl Cidade de Rio das Ostras was converted into a floating production storage and offloading (FPSO) vessel in 2007. This former tanker is now capable of processing up to 15,000 barrels a day. Currently, it is producing oil from the Siri reservoir, some 85 kilometres off the Brazilian coast.
The conversion included the installation of a bow offloading system, a flare tower, mooring arrangements, a variety of oil processing modules, a riser balcony and laydown area, a boiler with auxiliaries, forward and aft offshore cranes, an extended control room, lifesaving appliances, and a helideck.
Wärtsilä was also responsible for the integrated engineering of electrical, automation, instrumentation and telecom systems. Safe operation of the FPSO vessel is enhanced through shutdown systems that can be triggered automatically or manually. The safety system was provided through Wärtsilä’s alliance with Emerson.
