Type 636/636A Haiyang 18 distant-ocean survey ships

Qian Xuesen is the most weighty name, and Deng Jiaxian and Qian Sanqiang, both of whom are two bombs and one star, are leaders who lead China to become a nuclear power, if China There are so many warships named after them in the Navy. Perhaps it is not used for aircraft carriers or frigates, but in fact, the "Qian Xuesen" ship (ship number 873), "Deng Jiaxian" ship (ship number 874) and "Qian Sanqiang" (ship number 875) in the Chinese Navy. The "Qian Weichang" ship (ship number 876) ships belong to the seemingly ordinary Zhongyuanhai survey ship. It can be said that these survey ships, named after two bombs and one star, and famous scientists, are the unique tools of the great navy, showing their great value in low-key way.

Submarine voyages must have a guide. Only by effectively mapping the submarine topographic map of the submarine's waters can the safety and concealment of submarine voyages be guaranteed. Therefore, designing and constructing a survey vessel is essential.

The PLAN operates a number of Haiyang [ = Ocean] Type 636/636A distant-ocean survey ships, analogues of the U.S. Navys Pathfinder class hydrographic survey ships. These ships perform bathymetric surveys and collect oceanographic and meteorological data, which serve as inputs for the production of charts and the development and improvement of forecasting systems. Indeed, the PLANs distant-ocean survey fleet has more than tripled since 2015.

Marine survey refers to the investigation of hydrological, meteorological, physical, chemical, biological, and sedimentary distribution and changes in a particular sea area. In the military field, marine surveys are also extremely important, including the study of ocean acoustics, the exploration of various topographical features on the seabed, and the use of deep-dive techniques. Only by fully understanding the ocean can opeartors maximize the effectiveness of weapons and equipment.

By the end of the 20th century, the 636-type marine integrated survey vessel Li Siguang was in service and was the first 5,000-ton ocean-going survey vessel designed and manufactured by China. Its advanced level at that time is undoubted, and it has not made outstanding contributions to China's marine sea survey business. However, in 2012, according to the needs of the country, the ship was retired in advance and handed over to the fishery administration department. It became the 206 fisherman of China Fishery Administration, which is now the 2,506 sea police, and became a frequent visitor to the Diaoyu Islands cruise law enforcement.

After the handover, the ship also carried out corresponding upgrades and modifications, such as the installation of side pushes, the replacement of work boats, the upgrading of marine equipment, etc., to better adapt to the identity of the official ship. According to another source, the original military investigation equipment on the ship has not been dismantled. It is not surprising that there have been too many examples of the navy wearing vests in these years. After all, it is a fine tradition.

The backbone of the Navy's current ocean-going comprehensive survey is the large-scale construction of the 636A survey vessel, which has been divided into two batches. A total of eight vessels have been built. Currently, five vessels are in service, one will be commissioned, and the other two have also been launched. The whole ship is equipped with more than 20 measuring systems, which can carry out water depth measurement, seabed geomorphology measurement and sea surface surface geological exploration, and has strong deep sea scanning test capability.

The first ship of the 636A is the nickname of the ship and is the star ship of the type. From May to October 2014, the Zhu Kezhen ship was ordered to perform the search mission of Malaysia Airlines MH370 lost passenger aircraft. It has crossed the equator twice, three times with the Malaysian and Australian delegations, and seven batches of international joint search and rescue. The center provides more than 4 million sets of data for sweeping test results. At the beginning of February 2015, the squadron was again ordered to travel and perform a 180-day round-the-world training combined with missions.

Ryan D. Martinson and Peter A. Dutton noted in 2018 that "Given the significant degree of civil-military integration in marine science, at least some Chinese distant-ocean cruises involve activities more akin to military surveys. That is, embarked scientists are collecting data primarily intended to serve military aims, not in order to increase scientific knowledge of the marine environment for the benefit of all mankind, as marine scientific research is defined in the United Nations Convention on the Law of the Sea. Chinas close civil-military integration differs markedly from the U.S. approach of clearly distinguishing between military surveyswhich are only conducted by U.S. Navy special mission shipsand marine scientific research, done by civilian academics aboard civilian-operated vessels."

The Type 636 Marine Integrated Survey Ship and its successor Model 636A are active investigation vessels of the Chinese People's Liberation Army Navy. The Type 636 Integrated Marine Survey Vessel and the successor Type 636A are designed by China Shipbuilding Corporation (CSSC) 708 (the China Ship and Ocean Engineering Design and Research Institute). This type of survey vessel pays special attention to vibration reduction measures, and its internal noise is much lower than other similarly sized vessels. The ship was built by the Wuhu Shipyard and began service in August 1998. On November 16, 2011, it was handed over to the Chinese Marine Police.

The head of the China National Maritime Supervision Corps said in an interview with the domestic media in 2008 that Chinas sea surveillance will strengthen its jurisdiction over disputed waters. He said, "In international law, there are two conventions for disputed waters. First, see if you have implemented effective management here. Second, actual control is better than historical proof. For example, we say that this area has always been ours, but this is useless, depending on whether you have actual control. The Chinese sea surveillance in the jurisdictional waters must show its existence and reflect effective jurisdiction." The Model 636A is an improved version of the Model 636. The first 636A was built at the Wuhu Shipyard in May 2003. The ship was fitted with more than 20 measuring systems. Originally named "Ocean Twenty", it was later renamed to "Zhu Kezhen". It was commissioned in 1998 and renamed China Fishery Administration 206 ships, and then changed its name to China Marine Police 2506. The second 636 was originally named "Ocean Twenty Two" and was later renamed "Qian Sanqiang". Type 636 and 636A ships are named after contemporary Chinese scientists.

876 "Qian Weichang" scientific research ship (Xiangyanghong No. 25)

On the morning of 25 July 2016, a new type of marine comprehensive survey vessel, Qian Weichang, was named in the flagship ceremony in a military port in Qingdao, Shandong Province, marking the official entry of the ship into the People's Navy battle sequence. It is understood that Qian Weichang, the ship number 876, is a new generation of marine integrated survey vessel developed by China. The vessel which has a displacement of 4,900 tonnes is manned by 158 officers and sailors. It has a length of 129 meters, a width of 17 meters and a full displacement of more than 6,000 tons. It is mainly responsible for marine hydrology, meteorology and underwater acoustic environment investigations and tasks such as ocean mapping.

A hydrographic survey ship of the Chinese Navy arrived at the port of Colombo on a four-day goodwill visit, the Sri Lankan Navy said 09 August 2018 'Qian Weichang', the ship of the People's Liberation Army Navy (PLAN), was ceremonially welcomed by the Sri Lankan Navy in accordance with the force's traditions upon its arrival yesterday. During the ship's stay in the country, the crew will participate in events organised by the Lankan Navy as well as visit places of tourist attraction in the island nation.

The arrival of the Chinese naval ship assumes significance in the wake of the communist giant recently gaining control of the Hambantota port in Sri Lanka, raising concerns that China could use the harbour for military purposes. Several media reports suggested that the deepwater port, which is near a main shipping route between Asia and Europe, is likely to play a major role in China's Belt and Road Initiative (BRI).

The BRI, also known as the Silk Road Economic Belt, is a development strategy proposed by the Chinese government which focuses on connectivity and cooperation between Eurasian countries. The Chinese government calls the initiative "a bid to enhance regional connectivity and embrace a brighter future". However, other nations see it as a push by China to take a larger role in global affairs with a China-centred trading network.
