Robert Allan Ltd. is has announced the signing of a new contract in November 2025 for the design of a TundRA 3100 icebreaking tug for the Port of Skellefteå, Sweden. This latest addition to the TundRA series is specifically engineered for the demanding conditions of Arctic and sub-Arctic ports, offering exceptional capabilities for icebreaking, ship assist, and escort services.
With the TundRA 3100, the Port of Skellefteå will benefit from enhanced ice management capabilities, reduced winter downtime, and improved safety for vessels operating in icy waters. The tug’s design and icebreaking performance make it an ideal choice for supporting the growth and resilience of northern ports that face challenging ice conditions.
The vessel will be equipped with electrically driven azimuthing propulsors, an electrical battery energy storage and a diesel power generation plant. The flexibility offered by this electric powering system will let the tug perform some ship assistance operations on electrical battery power alone without engaging diesel engines. This will save fuel, cut emissions, and reduce maintenance costs.
The RIM-Drive tunnel thruster will allow for heading control during buoy-tendering/fairway management duties.
