Designed by Wärtsilä ship Design and built by Kleven Verft AS in Norway, the Viking Energy is the world's first LNG-powered supply vessel.
The owner, Eidesvik Shipping AS, is a Norwegian consolidated group of companies managing a worldwide fleet of purpose-built vessels and providing services for, among other things, the offshore market. The vessel was delivered in April 2003, and is chartered to Statoil for delivering supplies to oil and gas platforms in the North Sea.
The Viking Energy has a diesel-electric propulsion plant with four Wärtsilä 6L32DF dual-fuel engines, each with an output of 2010 kW at 720 rpm, driving the main generating sets. The engines run on liquefied natural gas (LNG) to reduce NOx emissions, but can also run on diesel oil. Should the gas supply be interrupted, they can be switched over from gas to liquid fuel automatically while continuing to deliver full power.
