Wärtsilä, the marine industry's leading solutions provider, has now been contracted to supply Wärtsilä 50DF dual-fuel propulsion engines to 100 Liquefied Natural Gas (LNG) Carrier vessels. This notable milestone was recently passed with the supply of a LNG carrier in a South Korean shipyard. The 100 LNG Carriers represent approximately one quarter of the current global fleet.
Wärtsilä's advanced dual-fuel technology was first launched in the early 1990s for use in land-based power plant applications. The first marine installation of the 50DF engine came a decade later. The technology enables the engine to be operated on either natural gas, light fuel oil (LFO), or heavy fuel oil (HFO), and switching between fuels can take place seamlessly during operation, without loss of power or speed. This ensures safety and continuous installation operability. The Wärtsilä 50DF engine is designed to have the same output regardless of the fuel used.
