MSV Fennica is a Finnish multipurpose icebreaker and platform supply vessel. Built in 1993 by Finnyards in Rauma, Finland and operated by Arctia Offshore, she was the first Finnish icebreaker designed to be used as an escort icebreaker in the Baltic Sea during the winter months and in offshore construction projects during the open water season. Fennica has an identical sister ship, Nordica, built in 1994.

The maximum overall length of Fennica is 116 metres (380.6 ft) and her length between perpendiculars is 96.7 metres (317.3 ft). The hull has a moulded breadth of 26 metres (85.3 ft) and depth of 12.5 metres (41.0 ft). Her draught varies between 7 metres (23.0 ft) as a Baltic icebreaker and 8.4 metres (27.6 ft) in Arctic conditions and offshore work. The gross tonnage of Fennica is 9,392, net tonnage 2,818 and deadweight tonnage ranging between 1,650 and 4,800 tons depending on the draft. The ship weighs 7,935 tons and has a maximum displacement of 12,800 tons.

Fennica is classified by Det Norske Veritas with a class notation 1A1 POLAR-10 Icebreaker Tug Supply Vessel SF HELDK EPR E0 DYNPOS-AUTR. Her ice class, POLAR-10, means that her hull is strengthened for unassisted operation in the Arctic, sub-Arctic and Antarctic regions, where the vessel can encounter winter ice with a nominal thickness of 1 metre (3.3 ft), pressure ridges, multi-year ice floes and glacial ice inclusions. The additional class notation "Icebreaker" states that she has no limitations for repeated ramming. To improve the maneuverability of the ship in ice her hull is wider at the bow than in the stern. These "reamers" increase the width of the ice channel and reduce friction between the hull and ice. In addition the forward part of the hull has explosion-welded stainless steel ice belt that reduces friction and protects the steel plates from abrasion.
