B198

B198 is a Finnish Voith-Schneider propulsion system, designed and manufactured for icebreaking operations. The system consists of a twin-screw configuration, with the screws separated by a wall or bulkhead. The Voith-Schneider system is a unique arrangement of the propellers and ducts to provide efficient propulsion in both fore and aft directions.

The B198 system is used on the Finnish icebreaker MS Väinämöinen, which was launched in 1961. The MS Väinämöinen is one of the largest and most powerful icebreakers in the world, operated by the Finnish Transport and Communications Agency (Liikenteen Tutkimuskeskus). The MS Väinämöinen has a length of 81 meters and a beam of 22 meters, and it is capable of breaking ice up to 2 meters thick.

The Voith-Schneider propulsion system in the MS Väinämöinen allows it to travel through ice and dense snow at speeds of up to 18 knots. The system also enables the ship to perform a variety of operations, including towing and cargo handling. The B198 system has been widely used in icebreaker design, and it remains an important component of modern icebreaking operations.

Throughout its service, the MS Väinämöinen has played a crucial role in maintaining Finland's maritime trade and providing aid in times of need. The ship's ability to operate in harsh, icy conditions makes it an essential part of the country's transportation network. The B198 propulsion system has been a reliable and effective component of the MS Väinämöinen's operations, enabling it to provide critical services to the nation.
