Provalys 154,000 m3 LNG carrier largest LNG carrier With Wärtsilä 50DF

When taken into service in 2006, the 154,000 m3 LNG carrier "Provalys" was the largest LNG carrier in existence. The ‘Provalys’ is propelled by dual-fuel engines and electric propulsion. The heart of the system is four dual-fuel engines; three 12-cylinder and one 6-cylinder Wärtsilä 50DF, giving a combined output of 39.9 MW.

The vessel is employed to carry liquefied natural gas (LNG) from Norway or Egypt. The propulsion solution for the ‘Provalys’ uses dual-fuel engines for electric power generation. The ship is designed to be capable of responding to the alternative of trading on the spot market.

The electric power is supplied to an electric propulsion system, as with the diesel-electric propulsion systems on modern cruise ships. The solution offers LNG carriers a number of significant advantages, including lower overall fuel consumption, fuel flexibility, and reduced emissions.
