Beijun 204 class series ships in PLAN service are designated by a combination of two Chinese characters followed by three-digit number. The second Chinese character is Jun (浚), meaning dredge in Chinese, because these ships are classified as dredgers. The first Chinese character denotes which fleet the ship is service with, with East (Dong, 东) for East Sea Fleet, North (Bei, 北) for North Sea Fleet, and South (Nan, 南) for South Sea Fleet. However, the pennant numbers may have changed due to the change of Chinese naval ships naming convention.
