Wärtsilä has further developed its dual fuel technology and introduced a more powerful version of the 34DF engine.

The Wärtsilä 34DF engine can be applied on a wide range of vessels. The latest version is expected to expand that range further. Lower fuel consumption of this engine will further improve its environmental performance.

500 kW per Cylinder

Since 2003, the Wärtsilä 34DF has paved the way in the LNG-fuelled offshore support vessel market. Today this product is being mainly used in tugs, ferries, Ro-Ro, Ro-Pax and workboats.The new and upgraded version of the 34DF engine increases the efficiency in both liquid and gas operating modes and offers a power increase up to 500 kw per cylinder.

Better Fuel Economy

This increased output means that the Wärtsilä 34DF now covers a power range from 2,9 MW to 8 MW. In addition to the increase in power, fuel economy is also enhanced, especially when operating in liquid fuel mode.

IMO Tier II and III

When operating in gas mode, the 34DF engine is compliant with IMO Tier III regulations without any secondary exhaust gas purification systems. Also when fuelled by gas, the SOx and CO2 emissions are notably reduced, and smokeless operation is attained.

In liquid fuel oil mode, the dual-fuel engines are compliant with the IMO Tier II exhaust emissions regulations set out in Annex VI of the Marpol 73/78 convention.

The engine is able to operate efficiently and economically on low sulphur fuels (<0.1% S), making it suitable for operation in emission-controlled areas. The engine has also been certified by the United States Environmental Protection Agency (EPA).
