Wärtsilä milestone a chance to reflect upon LNG as a ship power source

TECHNOLOGY group Wärtsilä’s Fuel Gas Supply System has recorded its 100th order booking.

Two new shuttle tankers built for Singapore’s AET Tankers are to feature Wärtsilä 34DF dual-fuel auxiliary engines running mostly on LNG fuel and fitted with LNGPac units.

The contract brought the total number of orders received for this system to 100.

The Wärtsilä LNGPac is said to have played an important role in establishing the viability of LNG fuel since being first introduced in 2009.

General manager fuel gas supply systems, Mathias Jansson, said a major reason for the global acceptance of LNG fuel for shipping was Wärtsilä realised more than just a dual-fuel engine and a stand-alone LNG system was required.

“LNG fuelled ships require a complete fuel handling system, and the innovative LNGPac system very successfully meets this requirement,” Mr Jansson said.

The first LNGPac installation was for the chemical tanker ‘Bit Viking’ which was converted for LNG fuel operation in 2011.

Today the LNGPac is installed on some 12 or more different types of vessel, including passenger ferries, tugs, dredgers and offshore vessels.

Since the original introduction of the LNGPac, Wärtsilä has reportedly continued to refine the system.

The company has, for example, pioneered the utilisation of the cold energy stored in LNG by using it to cool the onboard HVAC and galley system.
