Wärtsilä has announced a contract to supply complete dual-fuel propulsion packages for two new liquefied ethylene gas (LEG)/liquefied petroleum gas (LPG) tankers being built for Dutch gas transport company Anthony Veder.

The ships are being built by AVIC-International Shanghai at the Avic-Dingheng Shipbuilding yard, due for delivery in mid-2014, and are intended for operation in the North Sea area. The propulsion packages, which include main and auxiliary engines, gearboxes and CP propellers, will be delivered in June 2013.

Each ship will be equipped with a 6L34DF main engine and two 6L20DF gensets. The dual-fuel (DF) main and auxiliary engines will allow the ships to operate on LNG, to reduce their environmental footprint, although the DF engine technology allows conventional marine diesel fuels to be used as an alternative. The switch between fuel types can be achieved without loss of power or speed. Operating on gas, the tankers will be able to sail without restrictions in ECAs, as the use of natural gas enables compliance with all sulphur and nitrogen emission restrictions, including future marine emissions legislation coming into force in 2016.

"We are delighted to supply these new tankers with Wärtsilä's dual-fuel engine technology, which will enable them to operate safely, economically, and sustainably on LNG fuel. This order strengthens our position as the market leader in terms of LNG fuelled propulsion machinery," said Aaron Bresnahan, vice-president of sales, Wärtsilä Ship Power.

According to Wärtsilä, more than 2,000 of the company’s gas fuelled engines are now in commercial operation in land-based and marine applications, and have accumulated a total of more than 7 million operational running hours.
