A new hybrid-powered icebreaking escort tug designed by Robert Allan Ltd is being built at Spain's Astilleros Gondan shipyard.
Being built for the Port of Lulea in Sweden, the 36-metre-long escort tug is designed to perform icebreaking, ice management, ship assist, coastal towing and emergency support.
Capable of breaking one metre of ice at a speed of up to three knots, the TundRA 3600-H is custom made for operations in the northern Gulf of Bothnia.
The hull structure is designed in excess of Finnish-Swedish Ice Class Rules.
The vessel, which can accommodate 10 people, will be equipped with a hybrid propulsion system featuring diesel main engines, shaft motor/generators, and electrical battery energy storage.
It can be operated on electrical battery power in transit, using a single main engine in diesel-electrical mode, and have a bollard pull of up to 100 tonnes.
The TundRA 3600-H can be connected and heated by the city district heating system and recharge batteries when at the quay.
