Tug provided 98 t bollard draw on examinations
The Port of Lule å, Sweden, has actually taken distribution of the 36 meter crossbreed icebreaker pull Vilja from Spanish shipbuilder Astilleros Gondan.

- Free running rate, in advance: 14.6 knots
The pull has a hull framework that goes beyond Finnish-Swedish ice-class stamina needs as well as was constructed to the highest possible ecological criteria. It will certainly be utilized for ice administration, firefighting as well as navigating help solution tasks in the Port of Lule å as well as will certainly help ships as well as carry out seaside towing in the north industry of the Gulf of Bothnia.

This setup permits efficient power as well as gas usage administration. The pull can operating the battery power just or using a solitary primary engine in the crossbreed diesel-electrical setting, or on 2 primary engines in diesel-mechanical setting with feasible battery increase. The resulting functional adaptability returns considerable gas, exhausts as well as upkeep financial savings.
Main propulsion is a crossbreed setup with in-line shaft electric motor generators (M/Gs) as well as consists of a set of Wärtsilä 8L26 diesel motor, each ranked at 2,720 kW at 1,000 rpm, as well as each driving a Rolls-Royce US355 controlled pitch Z-drive system, ranked 3,100 kW at 1,000 rpm. The extra increase is offered by 2 shaft motor/generators, as well as electric battery power storage space.
The pull is the initial vessel geared up with the Wärtsilä HY crossbreed power component. The component gives optimum power administration as well as electric procedure.
