Finnish operator Alfons Håkans recently took delivery of a new ice class ASD harbour tug for operation in the northern Baltic Sea.
Named Ajax by its new owner, the tug is based on a design from Canadian naval architecture form Robert Allan Ltd and has been uniquely designed to meet the operator's individual needs.
Measuring 25.8 metres LOA with a moulded beam of 11.8 metres, a least moulded depth of 5.2 metres and a navigational draught of 5.05 metres, Ajax can perform multiple tasks including escort, ship assist, icebreaking and ice management, and open sea towing.
The tug's two Caterpillar 3512E main engines produce an over stern bollard pull of 60 tonnes and a free running speed of 12 knots. Caterpillar also supplied a selective catalytic reduction (SCR) system to ensure that the tug complies with IMO Tier III NOx emissions standards and the American Bureau of Shipping's NOx notation.
The deck equipment includes a heavy-duty winch on the fore deck for ship-assist duties and a foldable knuckle boom crane. Tank capacities include 75.2 cubic metres for fuel oil.
Ajax will be capable of operating alongside Alfons Håkans' other vessels year-round in the often harsh conditions of the Baltic Sea.
