Type 636
editType 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 China Shipbuilding and Oceanic Engineering Design Academy (中国船舶及海洋工程设计研究) Archived 2019-07-06 at the Wayback Machine 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. Specification:[5]

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.[6][7]
