APRIL 12, 2013 — Wärtsilä says that its Wärtsilä 34DF dual-fuel engine is the first dual-fuel engine to receive U.S Environmental Protection Agency (EPA) certification of emission standard compliance.The certification was obtained on January 17, 2013.

The EPA certification enables Wärtsilä to strongly enter the American market with marine engine technology that offers operators and owners the option of using either diesel or gas as fuel.

The first of the EPA-certified Wärtsilä dual-fuel engines will equip the Harvey Energy, the first in a series of LNG-fueled offshore supply vessels being built for Harvey Gulf International Marine at TY Offshore.

"Economic and environmental factors are having a tremendous impact on the shipping industry, and at Wärtsilä we firmly believe that flexible fuel options are a positive step in alleviating these challenges. Our dual-fuel engine technology enables environmental legislation to be met where necessary, while maintaining the ability to use conventional diesel fuel in unrestricted areas," says Giulio Tirelli, Director, Wärtsilä Ship Power, 4-stroke Portfolio & Applications.
