Two New Gas Tankships to Fit Wärtsilä DF Propulsion Packages
Wärtsilä to supply complete dual-fue (DF) propulsion packages for two new gas tankers being built for owners, Anthony Veder.
The contract was signed with AVIC-International Shanghai and Avic-Dingheng Shipbuilding Co. Ltd yard, for the two Liquefied Ethylene Gas (LEG)/Liquefied Petroleum Gas (LPG) tankers being built for Anthony Veder, the Netherlands-based shipping company specialised in gas transportation, for deployment in the North Sea.
The propulsion package, which includes the main and auxiliary engines, gear boxes and controllable pitch propellers, will be delivered in June 2013, and the tankers are scheduled for delivery in mid 2014.
The Wärtsilä dual-fuel (DF) main and auxiliary engines will allow the ships to operate on liquefied natural gas (LNGLF) (LNG), which minimises 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.
Each vessel will be equipped with:
- 1x 6-cylinder in line Wärtsilä 34DF main engine
- 2x 6-cylinder in line Wärtsilä 20DF auxiliary gensets
- Wärtsilä Gears
- Wärtsilä Controllable Pitch Propellers
