Tan Suo San Hao

Tan Suo San Hao is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tan Suo San Hao rather than just read about it. In short: Tan Suo San Hao (simplified Chinese: 探索三号; traditional Chinese: 探索三號; lit. 'Discovery Three') 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.

Key takeaways

Tan Suo San Hao belongs to mathematics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Tan Suo San Hao to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Tan Suo San Hao from memory before moving on to harder problems.

Reference excerpt

Tan Suo San Hao (simplified Chinese: 探索三号; traditional Chinese: 探索三號; lit. 'Discovery Three') 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 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). 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. A 6 by 4.8 metres (20 by 16 ft) moon pool allows deploying and recovering autonomous underwater vehicles in ice-covered waters. 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. 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. Tan Suo San Hao is built to Polar Class 4, 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.

History

Development and construction Tan Suo San Hao is claimed to be the first research vessel of its kind developed indigenously in China. 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. 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. The vessel, named Tan Suo San Hao, was floated out on 20 April 2024. The vessel completed the final series of sea trials in October 2024.

Career Tan Suo San Hao was delivered on 26 December 2024.

Worked examples

Example 1 — a first encounter with Tan Suo San Hao

Start with the simplest possible case. Write down what Tan Suo San Hao claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tan Suo San Hao before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tan Suo San Hao ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tan Suo San Hao

In research: Tan Suo San Hao appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tan Suo San Hao in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tan Suo San Hao is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2024 ships, IMO numbers, Icebreakers of China, so understanding it makes those chapters shorter.
In everyday life: Look for Tan Suo San Hao outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
