Vasiliy Poyarkov (Russian: Василий Поярков) was a Soviet icebreaker in service from 1963 until 1988. It was one of twelve Project 97A icebreakers built by Admiralty Shipyard in Leningrad in 1961–1971.

Description

In the mid-1950s, the Soviet Union began developing a new diesel-electric icebreaker design based on the 1942-built steam-powered icebreaker Eisbär to meet the needs of both civilian and naval operators. Built in various configurations until the early 1980s, the Project 97 icebreakers and their derivatives became the largest and longest-running class of icebreakers and icebreaking vessels built in the world. Of the 32 ships built in total, the unarmed civilian variant Project 97A was the most numerous with twelve icebreakers built in 1961–1971.

Project 97A icebreakers were 67.7 metres (222 ft) long overall and had a beam of 18 metres (59 ft). Fully laden, the vessels drew 5.35 metres (17.6 ft) of water and had a displacement of 2,935 tonnes (2,889 long tons). Their three 1,800-horsepower (1,300 kW) 10-cylinder 13D100 two-stroke opposed-piston diesel engines were coupled with generators that powered electric propulsion motors driving two propellers in the stern and a third one in the bow. Project 97A icebreakers were capable of breaking 70 to 75 centimetres (28 to 30 in) thick snow-covered ice at very slow but continuous speed.

History

The fourth of twelve Project 97A icebreakers was laid down at Admiralty Shipyard in Leningrad on 13 August 1962, launched on 16 March 1963, and delivered to the Far East Shipping Company on 26 July 1963. Initially named simply Ledokol-4 (Russian: Ледокол-4), Russian for "icebreaker", it was renamed Vasiliy Poyarkov in 1966 after the 17th century Russian explorer. The icebreaker was stationed in Vladivostok in the Russian Far East.

Vasiliy Poyarkov was one of the numerous icebreakers involved in the shipping crisis in the Soviet Eastern Arctic where unprecedented ice conditions caused a major disturbance to shipping at the end of the 1983 navigating season.

Vasiliy Poyarkov was taken out of service in 1988 and, after its name was shortened to Poyar, sold to China for scrapping.
