The Wärtsilä power packs, producing more than 100MW in total, in the new P-63 FPSO vessel have completed full 100% load tests at the Cosco shipyard in Dalian, China, in preparation for the start of operations in Brazil's offshore oil fields.

The FPSO has three separate power generation modules, each comprising two 18-cylinder Wärtsilä 50DF dual-fuel engines, alternators and auxiliary equipment. When in operation at the Papa-Terra oilfield, the modules will supply power to the drilling rig as well as the FPSO itself. The P-63 is said to be the first such ship to use gas engines to produce more than 100MWe of power

According to Wärtsilä, the engines are capable of being run on treated well gas or treated crude, as well as marine diesel oil (MDO), which means that virtually no MDO will need to be shipped to the P-63, reducing operating costs. The gas-fired power solution offers significantly lower levels of CO2 emissions compared to conventional technologies. In real terms, the company estimates that the level of carbon emissions will be reduced by as much as 93,000t/year.

Wärtsilä was contracted by the Brazilian industrial group Quip to provide a turnkey package for the P-63, which includes the three main power modules, commissioning, start-up, and operational supervision.

"This validation of the Wärtsilä technology represents a milestone event, and one that demonstrates Wärtsilä's capability to execute complex integration projects for the oil and gas industry with a solution that contributes notably to successful client operations. The Wärtsilä turnkey project model is an effective means to enhance project completion targets. We have enjoyed working closely with our client, Quip, and look forward to the final tests when the FPSO is on location at Brazil's offshore Papa-Terra field," says Magnus Miemois, vice-president, solutions, Wärtsilä Ship Power Offshore.
