This is a list of icebreakers and other special icebreaking vessels (except cargo ships and tankers) capable of operating independently in ice-covered waters. Ships known to be in service are presented in bold .
The ship was built for the People's Liberation Army Navy in 1982 as Haibing 723. [1] and operated as a spy ship in the North Sea Fleet.[3]In May 2000, the ship transited the Tsugaru Strait, conducted surveillance near Tsushima Island for seven days starting on May 14, and passed through the strait three times from May 23 to 26 to surveil the Cape Tappi "guard station."
Prior to ocean-going ships, ice breaking technology was developed on inland canals and rivers using laborers with axes and hooks. The first recorded primitive icebreaker ship was a barge used by the Belgian town of Bruges in 1383 to help clear the town moat.
MSV Fennica is a Finnish multipurpose icebreaker and offshore support 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.
MSV Nordica is a Finnish multipurpose icebreaker and offshore support vessel. Built in 1994 by Finnyards in Rauma, Finland, and operated by Arctia Offshore, she and her sister ship Fennica were the first Finnish icebreakers designed to be used as escort icebreakers in the Baltic Sea during the winter months and in offshore construction projects during the open water season.
MSV Botnica is a multipurpose offshore support vessel and icebreaker built by Finnyards in Rauma, Finland in 1998. She was the newest and technically most advanced state-owned icebreaker of Finland until 2012, when she was sold to the Port of Tallinn, Estonia for 50 million euro. [4]

As part of these plans that were published in the early 1990s, a number of both conventional and nuclear-powered icebreaker icebreaker type size series were developed, ranging from 7-megawatt auxiliary icebreakers (LK-7) operating near large ports to 110-megawatt nuclear icebreakers (LK-110Ya) capable of breaking ice up to 3.5 metres (11 ft) thick.
