The technology group Wärtsilä’s hybrid power module solution, the Wärtsilä HY, is now fully operational on the ‘Vilja’, an escort tug owned by the Swedish port of Luleå. The tug was built at Gondan Shipbuilders in Asturias, Spain and was delivered in the end of June 2019 following successful completion of the commissioning and sea trials. The Wärtsilä HY is the first hybrid power module in the marine industry, and its operational application onboard the ‘Vilja’ marks a new era in shipping.
