Finnish marine solutions and services provider Wärtsilä has completed full load tests of a new P-63 floating production storage and offloading (FPSO) vessel for the offshore oil and gas industry.
The vessel, which will begin operations in the oil fields offshore of Brazil in 2013, was tested at the Cosco shipyard in Dalian, China.
Powered by Wärtsilä’s 50DF dual-fuel engines, it is said to be the first such vessel to utilise gas engines to generate more than 100MWe of power.
Dual-fuel engines will enable the ship to run on treated well gas or treated crude and marine diesel oil (MDO), reducing the operating costs significantly, allowing the vessel to travel without any MDO.
In addition, the gas-fired power solution installed over the vessel is expected to reduce carbon emissions by about 93,000 tonnes per year, compared to other conventional technologies, said Wärtsilä.
Wärtsilä has provided a turnkey package for the P-63 FPSO vessel as part of a contract awarded by Brazil-based QUIP.
As part of the contract, Wärtsilä will supply three main power modules, each containing two 18-cylinder 50DF engines in a V-configuration, alternators, auxiliary equipment, commissioning, start-up and operational supervision.
Wärtsilä Ship Power Offshore Solutions vice president, Magnus Miemois, said the vessel will be deployed at the Papa-Terra field offshore of Brazil after completing the final tests.
Located in block BC-20 of the Campos Basin, Papa Terra field is a heavy crude oil field, which lies at a water depth of 1,190m, about 110km offshore Brazil. Petrobras operates the field with a 62.5% interest, while the remaining 37.5% interest is held by Chevron.
The field is estimated to hold about 700 million to nearly a billion barrels of oil equivalent, while the crude oil has an API index ranging between 14° and 17°. It is, however, expected that about 380 million barrels of oil will be recovered from the field.
