from Wikipedia, the free encyclopedia

The Yermak ( Russian Ермак ; German transcription Yermak ) is a Russian icebreaker . The ship was built in 1973 and bears the name of the historic Russian steam icebreaker Jermak from 1898.

description

The three-screw icebreaker Jermak ( IMO number 7330038) was manufactured as the lead ship of a series of three polar ice breakers with 36,000 WPS (26,500 kW) diesel-electric drive units. It was built in 1973/1974 as hull number 398 by the Finnish Wärtsilä shipyard on behalf of the Soviet Union . The icebreaker was specially developed for use on the northern sea route. The ship has a crew of 118 men. Because of the particularly harsh climatic conditions and the long period of use, the crew accommodations and leisure rooms are designed to be functional and particularly comfortable. The ship was in service with the Russian shipping company FESCO until 2000 . It was taken over by the Saint Petersburg Port Authority on August 9, 2000 and is still in service in the Baltic Sea today .

With a total length of 134.85 meters, the width on the frames is 25.99 meters and the overall width is 26.07 meters. The icebreaker has a draft of 10.96 meters and a side height of 16.72 meters. The water displacement is about 20,200 tons. A total of nine generators powered by twelve-cylinder, two-stroke Sulzer 12ZH40 / 48 diesel engines provide the power required for the diesel-electric drive. A single unit delivers 4,600 hp (3,385 kW). In addition, six diesel generators, each with an output of 1,200 PS (883 kW), form the auxiliary power system. Two further 883 kW diesel generators generate the electrical energy required for the air blower system. With the power of the propeller electric motors of 3 × 12,000 HP, the ship in the bollard pull achieves a thrust of 3,100 kN (about 310 tons) at ice barriers. The maximum free speed is 19.5 kn. In addition, the Jermak can tow other ships with the help of a tow winch. The icebreaker has a helicopter as well as a hangar and the required landing platform for assistance and exploration .
