Multipurpose icebreakers for the Finnish National Board of Navigation.

Author(s) : LOHI P.

Summary

These icebreakers are a completely new type of vessel. The hull form successfully combines the functions and requirements of two completely different vessel types: an icebreaker and an ocean going offshore vessel with good seakeeping properties. To guarantee the vessels' superior manoeuvring properties in all conditions, the vessels are equipped with two azimuth propulsion units of 7500 kilowatts each, being the most powerful of this kind in the world, and also with three bow thrusters. For accurate track/position keeping, a fully redundant dynamic positioning system has been installed on-board the vessels. The performance of the vessels is discussed.
