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 fitting of Wärtsilä 50DF engines onboard the first LNG Carriers in 2006 set a trend in the industry. Since that introduction, 65 percent of all new LNG Carriers have been fitted with Wärtsilä dual-fuel engines.
In addition to its success in the LNG Carrier market, the Wärtsilä 50DF engine is increasingly being considered by owners and operators throughout the shipping industry. For example, in the cruise and ferry sector, where it is often necessary to operate in Emission Control Areas (ECAs), there is growing awareness of the advantages of operating on gas.
Similarly, vessels serving the offshore oil and gas industry are increasingly being fitted with Wärtsilä dual-fuel engines. The need for flexibility, fuel efficiency, and compliance with stricter environmental regulations, are the drivers behind this trend.
