Wärtsilä reports that it has been contracted by STX Finland in Turku to supply the main engines for a new multi-purpose cargo vessel, being built for Meriaura, a Finnish carrier of industrial products and general cargo.

The ship will be powered by three Wärtsilä 6L20 main generating sets, capable of operating on various types of liquid bio-fuels (LBF), which can be produced from various raw materials of vegetable and non-vegetable origin. The gen-sets will be capable of using marine diesel oil as a backup fuel.

The onboard fuel system is prepared for regular operation with LBF, and the sea acceptance trials for the owner are to be conducted using liquid bio-fuel. The new vessel, the Aura II, is a multi-purpose dry cargo deck carrier that can also be used for oil recovery operations in the Baltic Sea. In addition, the ship is designed for the transport of heavy modules to the offshore industry in the North Sea basin. When not operating as a deck carrier, the 4,350dwt ship is designed also as a container carrier. It is scheduled to be delivered in spring 2012.

This will be the first installation ever where a European commercial shipping operation will permanently use LBF as fuel. The fuel is produced at the ship owner's process refinery in Uusikaupunki, on the south-west coast of Finland. Advanced training on the Wärtsilä engines will be provided to the operator crews at the Wärtsilä Land & Sea Academy training centre in Turku, Finland. Wärtsilä already maintains and services Meriaura’s Aura, under a maintenance contract agreement.

"This contract clearly demonstrates Wärtsilä's ability to supply environmentally sustainable power solutions without substantial impact on costs to operators and investors. Our technology leadership in engines with diversified and flexible fuel supply options, and our ability to install a compact central diesel electric power plant in an engine room with confined space, were major factors in the award of this contract," says Jukka Paananen, business manager, Wärtsilä Ship Power.
