Wärtsilä provides power modules for FPSO

Oilfield Technology,

Wärtsilä has signed a contract with the Brazilian industrial group QUIP to supply three main power modules for a new P-63 floating production storage and offloading (FPSO) vessel.

Gas fired power solution
The vessel is unique in that it will be the first FPSO to utilise gas engines to produce more than 100 MWe of power. The contract includes commissioning, startup and operational supervision. The power modules will be ready for installation in July 2011 and oil production is scheduled to begin in 2013. The vessel will operate on Brazil's new Papa Terra oilfield, located approximately 110 km off the coast of Rio de Janeiro in the southern Campos Basin.

According to Magnus Miemois, Vice President, Offshore, Wärtsilä, ‘Since the engines can run on treated well gas or treated crude, as well as marine diesel oil (MDO), virtually no MDO will need to be shipped to the P-63. This will notably reduce operating costs. Furthermore, this efficient gas fired power solution will also have significantly lower levels of CO2 emissions compared to conventional technologies. In real terms, it is estimated that the levels of carbon emissions will be reduced by as much as 93 000 tpy.’ 

Designed and produced by Wärtsilä, each power module will include two 18 cylinder 50DF tri-fuel engines in V-configuration, as well as alternators and all required auxiliary equipment.

P-63 project
BW Offshore and QUIP signed the contract for the P-63 FPSO with the Papa Terra BV joint venture partners, Petrobras (operator) and Chevron, at the very end of January. The field development concept involves the P-61 tension leg wellhead platform coupled to the P-63 FPSO.

The 323 000 t ultra large crude carrier (ULCC), the 'BW Nisa', will be utilised for the P-63 project. BW Offshore will deliver the marine scope of the FPSO conversion, including the hull, the offloading systems and mooring equipment. QUIP will provide the topsides facilities on the P-63 to process approximately 140 000 bpd of crude oil, 35 million ft3/d of gas, and 325 000 bpd of produced water. Facilities to inject approximately 340 000 bpd of seawater will also be also included. QUIP and BW Offshore will jointly operate the FPSO for a period of three years with a gradual handover to Petrobras.
