Controllable Pitch Propeller by Wartsila
Wärtsilä announced today they have been contracted to supply the complete dual-fuel propulsion package for two 4700 CBM Liquefied Ethylene Gas (LEG)/Liquefied Petroleum Gas (LPG) tankers being built for Netherlands-based gas transportation company Anthony Veder. Construction began this past September at Avic-Dingheng Shipbuilding in Yangzhou, China with an expected delivery date of mid-2014.
The Wärtsilä dual-fuel 34DF main and 20DF auxiliary engines will allow the ships to operate on liquefied natural gas (LNG), which minimizes their environmental footprint. However, fuel flexibility, a primary benefit of the Wärtsilä DF engine technology, means that conventional marine diesel fuels can also be used if required. The switch between fuel types is made seamlessly without loss of power or speed.
The use of Wärtsilä’s dual-fuel engine technology will enable these tankers to sail without restrictions in Sulphur Emission Control Areas (SECAs) and Nitrogen Emission Control Areas (NECAs). Natural gas is the most environmentally-sound fuel today, and it fulfils current actual and known 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,” says Aaron Bresnahan, Vice President, Wärtsilä Ship Power, Sales.
The propulsion package, which includes the main and auxiliary engines, gear boxes and controllable pitch propellers, will be delivered to the yard in June 2013. Upon final commissioning and delivery by the shipyard, the ships will be operated on contract in the North Sea region.
