Viking Line STX EuropeWärtsilä's scope of supply :-four Wärtsilä 8L50DF main engines, tunnel thrusters, and two stainless steel fixedpitch, built-up main propellers with complete propeller shaft lines andenvironmentally sound shaft line seal systems (Press release 03 March 2011)- Two LNGPacs (Press release 21 March 2011)This unique and groundbreaking vessel will be the most environmentally sound largepassenger ferry in the world. Thanks to Wärtsilä's technology, this ship will meet andeven exceed the most stringent known future IMO and EU environmental regulationsfor maritime applications. Wärtsilä's long experience and strong competence in dualfueltechnology, with some 300 such engines already sold, was an important reasonfor Wärtsilä being awarded this order," says Tony Öhman, Senior Vice President,Marine Operations & Newbuilding, Viking Line Abp© Wärtsilä presentation Göran Hellén 26/27
