Owned by Alfons Håkans, a tugboat owner and operator headquartered in Finland, the vessel will be flagged in Estonia and is the first of a pair of new tugs for this client. These new tugs are specifically designed for year-round service in the Baltic Sea and the Northern part of the Gulf of Bothnia, which is covered with heavy ice in wintertime, lasting up to 3 three months. The TundRA tugs are capable of performing tasks including escort, ship assist, icebreaking, ice management and open sea towing. The tugs has the capability to carry provisions of fresh water to visiting merchant ships and up to 25t of deck cargo in two 20ft containers. The 31.5m tug is designed to combine good seakeeping with relatively high speed in open water and offering effective icebreaking capability.

Deck machinery comprises a Rolls-Royce hydraulic double drum escort winch and one hydraulic vertical anchor windlass at the bow. The escort winch is spooled with a high-performance synthetic towline on each drum. In addition, a towing hook is provided on aft deck. A dry and heated rope store is arranged under the winch with convenient and safe access from the forecastle deck and from the lower accommodation deck. An 18t Palfinger hydraulic knuckle boom marine crane is fitted on aft deck with 14m outreach.

Main propulsion comprises a pair of Caterpillar 3516C, IMO Tier II certified diesel engines, each rated 2000kW at 1600 rpm, and driving a Rolls-Royce US 255 P30 CP Z-drive unit with 2.6 m propeller in a nozzle. The electrical plant consists of two identical Caterpillar C7.1 ship service generators, each with a power output of 118kWe at 50Hz.
