Wärtsilä 31 ‘Game Changer’ ‘Game Changer’ Debuts in Oslo t press-time in Oslo at Nor-Shipping 2015 Wärtsilä gave a lavish launch to the new Wärtsilä 31 engine. While

the Wärtsilä 31 engine’s highest fuel ef? ciency levels, with its diesel fuel consumption being as low as 165 g/kWh. The Wärtsilä 31 engine is de- signed to serve various types of vessels in the off- shore, cruise and ferry, and other marine segments where the power range requirement is from 4.2 to 9.8 MW. The engine can be operated using a range of different fuels, and comes in three alternative versions; Diesel, Dual-Fuel (DF) and Spark-Ignit- ed Gas (SG). The multi-fuel capabilities that the

Wärtsilä 31 brings to the market extend the pos- sibilities for operators to utilize different qualities of fuels, from very light to very heavy diesel, and a range of different qualities of gas.
