Type 636
Type 636 hydrographic survey ship and its successor Type 636A are both designed by of the 708th Institute of China State Shipbuilding Corporation (CSSC), which is also more commonly known as [http://maric.cssc.net.cn/ China Shipbuilding and Oceanic Engineering Design Academy (中国船舶及海洋工程设计研究)] {{Webarchive|url=https://web.archive.org/web/20190706013011/http://maric.cssc.net.cn/ |date=2019-07-06 }} nowadays. Special attention was given to vibration reduction measures and the internal noise generated by the ship itself was much lower than other ships of similar size. The ship was built by Wuhu Shipyard and entered service in August 1998. On November 16, 2011, it was transferred to Chinese Coast Guard.

Type 636A
Type 636A is the successor of earlier Type 636. Construction of the first ship of Type 636A began at Wuhu Shipyard in May 2003 and there are {{Clarify|date=January 2015}} more than two dozen surveying systems installed on board.
Each ship has two names, one used with the pennant number when on naval service, and another when working in civilian roles. The former are the names of eminent scientists and the second in a Hai Yang (海洋, "ocean") numbered series.{{cite web |title=Type 636/636A Haiyang 18 distant-ocean survey ships |url=https://www.globalsecurity.org/military/world/china/type-636-specs.htm |publisher=GlobalSecurity.org |access-date=13 April 2024 |archive-url=https://web.archive.org/web/20210825123544/https://www.globalsecurity.org/military/world/china/type-636-specs.htm |archive-date=25 August 2021 |location=Alexandra VA |date=1 August 2021 |url-status=live}}{{cite web |title=我海军这批军舰以科学家命名 毫无武装却可纵横全球 (These warships of our navy are named after scientists.
