Wärtsilä has been contracted to supply the complete dual-fuel—natural gas and diesel fuels—propulsion package for two new Liquefied Ethylene Gas (LEG)/Liquefied Petroleum Gas (LPG) tankers being built for Anthony Veder, the Netherlands-based shipping company specialized in gas transportation.
The contract was signed with AVIC-International Shanghai and Avic-Dingheng Shipbuilding Co. Ltd yard in September 2012. The ships are being built at the yard and they will operate in the North Sea area.
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.
Each vessel is equipped with:
- 1x 6-cylinder in line Wärtsilä 34DF main engine
- 2x 6-cylinder in line Wärtsilä 20DF auxiliary genset
- Wärtsilä Gears
- Wärtsilä Controllable Pitch Propellers
The Wärtsilä dual-fuel (DF) main and auxiliary engines will allow the ships to operate on liquefied natural gas (LNG), which reduces 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 fulfills current actual and known future marine emissions legislation coming into force in 2016.
More than 2,000 gas fueled Wärtsilä engines are now in commercial operation in both land-based and marine applications. Together, they have accumulated more than 7 million operational running hours.
