36 meter-class floating pile driver

36-meter class floating pile driver is a class of little known naval auxiliary ship currently in service with the People's Liberation Army Navy (PLAN). The name of this class is after the first unit commissioned, with the exact type still remains unknown, and a total of two of this class have been confirmed in active service as of mid-2010s.

36-meter class floating pile drivers in PLAN service are designated by a combination of two Chinese characters followed by three-digit number. The second Chinese character is Gong (工), short for Gong-Cheng (工程), meaning engineering in Chinese, because these ships are ships built for engineering projects. 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. The pile of this type of ship can be folded backward toward the superstructure to reduce overall height of the ship.
