Tan Suo San Hao
- An early draft of this article was ported from the wikipedia, were it had been drafted by Tupsumato
Tan Suo San Hao (Template:Zh) is a Chinese icebreaking research vessel operated by the Institute of Deep-sea Science and Engineering of the Chinese Academy of Sciences. The vessel entered service in December 2024.
Concurrently with Tan Suo San Hao, Guangzhou Shipyard International built a slightly smaller Polar Class 6 research vessel, Ji Di, which entered service in June 2024.
Design
[edit | edit source]Tan Suo San Hao measures 104 metres (341 ft) in length overall and 19.7 metres (65 ft) in beam, draws 6.7 metres (22 ft) of water, and displaces 9,300 tonnes (9,200 long tons).[1][2][3][4] The vessel has a multidisciplinary scientific outfit with accommodation for 32 crew and up to 48 scientists as well as ability to deploy China's deep-sea research submersibles Striver, Deep Sea Warrior, and Jiaolong.[1][4] A 6 by 4.8 metres (20 by 16 ft) moon pool allows deploying and recovering autonomous underwater vehicles in ice-covered waters.[5]
Tan Suo San Hao's diesel-electric propulsion system consists of four 3,000-kilowatt (4,000 hp) six-cylinder Wärtsilä 6L32 main diesel generators that power the ship's two 4.5-megawatt (6,000 hp) ABB Azipod DI1400 azimuth thrusters.[3][6] This will give the vessel a maximum speed of 16 knots (30 km/h; 18 mph) in open water and enables it to break 1.2-metre (3.9 ft) level ice with a 20-centimetre (7.9 in) snow cover at a continuous speed of 2 knots (3.7 km/h; 2.3 mph) in both ahead and astern directions.[4][7]
Tan Suo San Hao is built to Polar Class 4,[7] an ice class intended for year-round operation in thick first-year ice which may contain small inclusions of old sea ice that has survived at least one melting season without melting completely.[8]

History
[edit | edit source]Development and construction
[edit | edit source]Tan Suo San Hao is claimed to be the first research vessel of its kind developed indigenously in China.[5] The ¥800 million ship has been jointly funded by the People's Government of Hainan, Sanya Yazhou Bay Science and Technology City, and the vessel's operator, Institute of Deep Sea Science and Engineering of the Chinese Academy of Sciences.[4][7]
The construction of the vessel began with a steel cutting ceremony at Guangzhou Shipyard International, a subsidiary of the China State Shipbuilding Corporation, on 25 June 2023.[9] The vessel, named Tan Suo San Hao, was floated out on 20 April 2024.[4] The vessel completed the final series of sea trials in October 2024.[10]
Career
[edit | edit source]Tan Suo San Hao was delivered on 26 December 2024.[11]
In October 2025 CGTN reported that the Fendouzhe had completed 43 diving operations, launched from the Tan Suo San Hao.[12]
In early January, 2026, the Tan Suo San Hao launched deep-diving manned submersible that explored an undersea ridge that connected Greenland and Siberia.[13]

China's independently designed and built "Tan Suo San Hao" (Exploration No. 3), the world's first manned deep-diving mother ship with ice-breaking capabilities, carried the "Fendouzhe" (Striver) manned submersible and completed 43 diving operations in the Arctic. Notably, the "Fendouzhe" and the "Jiaolong" manned submersibles conducted joint underwater operations, pioneering a new model of dual-manned submersible collaboration in China.
