DESCRIPTION OF THE PROJECT

A new type of icebreaker that uses its asymmetric hull to break ice sideways is built at Finland’s Arctech Helsinki Shipyard. The vessel is being built in co-operation with Kaliningrad, Russia, based Shipyard Yantar JSC, that has produced the blocks of the vessel.The icebreaking multipurpose emergency and rescue vessel Baltika is being built for the Russian Federal Agency of Sea and River Transport and will be operated by the FGI Gosmorspassluzhba (Russian Marine Emergency Rescue Service). It will be used in icebreaking, rescue and

oil spill response operations in the Gulf of Finland. The vessel features an asymmetric hull, built-in oil recovery system and three 360 degrees rotating propulsors, which allow the vessel to operate efficiently sideways, astern and ahead. In the oblique mode the vessel will be able to generate a 50 m wide channel in 0.6 m thick ice. Baltika is thus the first icebreaker ever that can break a channel in ice that is twice as wide as its own breadth.
