MV Xue Long 2 (simplified Chinese: 雪龙2; traditional Chinese: 雪龍2; pinyin: Xuě Lóng 2; lit. 'Snow Dragon 2') is a Chinese icebreaking research vessel that entered service in 2019. She follows the naming of MV Xue Long, China's first polar research vessel.[3]

History

The 5 million euro[4] design contract for China's first domestically-built polar research vessel was signed in 2012 with the Finnish engineering company Aker Arctic, though construction did not begin until December 2016.[3] She was built at Jiangnan Shipyard.[3]

Xue Long 2 now in service both as a supply vessel for China's research facilities in the Arctic and Antarctic regions and as a research vessel, with capabilities for geological and biological experimentation and surveying.[5]

Design

Xue Long 2 measures 122.5 metres (402 ft) long, with a beam of 22.3 metres (73 ft) and a draft of 8.3 metres (27 ft) at full load.[5] She has a displacement of 14,300 tonnes.[5] She has a diesel-electric propulsion system, with two 8-cylinder and two 12-cylinder engines, both Wärtsilä 32-series designs,[6] powering two 7.5 MW Azipod propulsion units that give her a speed of up to 15 knots (28 km/h; 17 mph) in open water and 3 knots (5.6 km/h; 3.5 mph) when breaking ice.[5] Her ice class is Polar Class 3 and she is able to break ice up to 1.5 metres (4.9 ft) thick while traveling either ahead or astern.[5]
