World’s Strongest ice-breaking escort Attraction delivered

Vilja includes a hybrid propulsion system along with a hull that can split 1 m of ice hockey up to 3 liters at the Port of Luleå, Sweden

New hybrid vehicle ice-breaking tug Vilja is likely to create a significant impact to yearlong harbour operations in Sweden. It was constructed by Gondan Shipbuilders at its shipyard at Ria del Eo, in Spain, since the world’s most powerful hybrid icebreaker tug.

This 36-m tug was finished by Gondan on 9 June and sailed into the Port of Gijón because of the sea trials. It had been delivered to the operator on 27 June and started its voyage into the Port of Luleå, Sweden, in which it’ll be used for ship assistance and provide coastal towage from the northern sector of the Gulf of Bothnia.

“Vilja signifies the most technologically advanced tug currently in operation,” states Port of Luleå primary executive Henrik Vuorinen. “The hybrid grid will guarantee a drastic reduction in emissions, putting new, higher standards for our support, and for the quality of existence in the Luleå area”

Vilja was built to Robert Allan’s TundRA 3600-H design and can be accredited by Lloyd’s Register. It has a hull structure which surpasses Finnish-Swedish ice-class principles and has high ecological standards. It’s a moulded breadth of 13 m and navigational draught of 7 m.

It may divide 1 m of ice up to 3 knots with reduced emissions. As an example, Vilja is equipped with an innovative Wärtsilä’s HYTug hybrid system that contains two Wärtsilä 26 diesel main motors, shaft generators/motors and batteries for energy storage.

The energy storage platform will be flashed from the onboard energy management system. Wärtsilä also provided the power distribution train as well as the integrated alarm and automation system.

Vilja comes with a bollard pull of approximately 55 tonnes when operating on electrical battery power or using a single primary engine. This is increased to approximately 90 tonnes of bollard pull on two motors and 100 tonnes, as analyzed during sea trials, even when battery increase capacity is included.

Vilja’s complete propulsion power is around 6,200 kW in hybrid boost mode, when it produces 20% less emissions than a conventional tug of this kind and dimensions.

Its hybrid propulsion”contributes to operational flexibility that yields significant fuel, emissions and maintenance economies,” says designer Robert Allan.

Gondan customised Vilja to operate in the extreme climate conditions it will face from the northern Gulf of Bothnia. The shipbuilders utilized Cadmatic 3D marine design applications for detailed engineering and production design.

Robert Allan claims the TundRA set of tug designs were especially developed”for operations in a full assortment of ice conditions” and are”uniquely designed for each particular ice course and set of working conditions”.

It’s supplied TundRA 3200 designs for two ice-breaking tugs Alfons Håkans purchased from Sanmar Shipyards of Turkey for year-round operations from the northern Baltic Sea. Sanmar maintained a keel-laying ceremony for its first of those tugs on 19 June 2019. They’re expected to enter service in Q4 2020.
