Powering P-63 off the coast of Rio

Sustainability assured 2011 The use of gas as a marine fuel has several benefits, both for the shipping industry and for society at large. Natural gas provides greater fuel flexibility, especially in connection with multi-fuel engines, and enables a significant reduction in emissions of all polluting substances. Wärtsilä has been awarded a breakthrough contract to deliver a totally integrated power solution for a new gas-fuelled Floating Production Storage and Offloading (FPSO) vessel.

The order includes three main power modules, each of which includes two 50DF tri-fuel engines, alternators and auxiliary equipment. It also covers the commissioning, start-up, and operational supervision of the equipment. The vessel is unique in that it will be the first FPSO vessel ever to operate on more than 100 MWe of installed gas engine power.

Wärtsilä’s efficient gas-fired power solution also features significantly lower levels of carbon dioxide emissions. Compared to conventional technologies, the CO2 emissions from a 100 MWe output installation can be reduced by as much as 93,000 tons per year. Furthermore, since Wärtsilä’s engines can be run on treated well gas, as well as various diesel oils, the customer’s operating costs can be notably reduced.

Installation of the power modules was completed in 2011. The vessel will operate on Brazil’s new Papa Terra oilfield, located some 110 kilometres off the coast of Rio de Janeiro in the southern Campos Basin.

“It is significant that Wärtsilä’s technology has been selected for this important project. It endorses the fact that our fully integrated power modules offer the high levels of reliability, availability, efficiency, and fuel flexibility required for successful offshore operations,” says Magnus Miemois, Vice President, Offshore, Wärtsilä. “Our technology enables customers to minimise both their operating costs and their environmental impact.”

This P-63 project represents a practical demonstration of how Wärtsilä’s broad portfolio of products and integrated, value adding solutions can serve the offshore industry. The broad scope of this oil & gas industry project and the complex delivery requirements entailed demand experienced project management and problem solving capabilities.
