Wärtsilä has been contracted to supply its 50DF dual-fuel propulsion engines to 100 Liquefied Natural Gas (LNG) Carrier vessels.
The milestone was passed with the supply of a LNG carrier in a South Korean shipyard. The 100 LNG Carriers represent about 25 per cent of the global fleet.
Dual-fuel technology allows the engine to run on either natural gas, light fuel oil, or heavy fuel oil, and switching between fuels can take place seamlessly during operation, without loss of power or speed. The engine also has environmental advantages.
Since the first fitting of Wärtsilä 50DF engines onboard LNG Carriers in 2006, 65 per cent of all new LNG Carriers have been fitted with Wärtsilä dual-fuel engines.
— This is indeed an important milestone for Wärtsilä, and for the shipping industry as a whole, says Lars Anderson, Vice President, Wärtsilä Ship Power, Merchant.
— It confirms not only our leading position in the LNG transportation sector, but also the viability of Wärtsilä dual-fuel engines.
Other sectors of the shipping industry, for example cruise and ferry operators, are also embracing the Wärtsilä 50DF engine.
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.
To date, Wärtsilä has sold 720 DF engines, and has accumulated more than five million running hours of experience with this technology.
