Type 631 tankers in PLAN service are designated by a combination of two Chinese characters followed by a three-digit number. The second Chinese character is You (油), meaning oil in Chinese, because these ships are classified as oilers. 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 are subject to change due to changes of Chinese naval ships naming convention, or when units are transferred to different fleets. Type 631 can be easily distinguished from other transport oilers by its transfer stations amid ship that enables it to carry out underway replenishment missions.[1] Another visual cue of this class is that from the bow to the midsection of the ship, there are three levels of freeboard, while all other Chinese tanker has a smooth curvy transition.[1] Specification:[1][2][3][4][5]
