Delivery of first vessel with
Wärtsilä HY hybrid technology

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 at the end of June, following successful completion of the commissioning and sea trials.

The system has been specially developed to meet the specific needs of the tug market. It features operating characteristics that include green mode, with zero emissions and no noise, a power boost that delivers a higher bollard pull than any other conventional solution of comparable size, and smokeless operation whereby no smoke is produced even during start-up of the main engines, Wärtsilä said.

The Wärtsilä HY for Tug concept enables various benefits in terms of environmental performance, and a significant reduction in fuel and maintenance costs. During trials, the icebreaking tug achieved a 100-tonne bollard pull, while producing approximately 20% fewer emissions than a comparable conventional vessel, according to the company.
