Development
On May 1, 1993, the uncompleted former Soviet naval ship was towed to Dalian shipyard from Ukrainian Kherson shipyard. In addition to the hull and subsystems, China also purchased the design, which was immediately modified to meet the Chinese needs. Chinese Academy of Sciences academician Mr. Zhang Wende (张文德), the original chief designer of the 2nd generation domestic Chinese replenishment ship was named as the chief designer and the program manager of this conversion project. On May 8, 1996, it entered Chinese service in South Sea Fleet, where it has remained until today. The pennant number was originally Nanyun (南运)-953, but later changed to 885, with name Qinghaihu (青海湖), and this upgraded ship became the 2nd generation Chinese replenishment ship, replacing the originally planned indigenous one.
The conversion project was deemed successful and worthy but Chinese, who had gained important insights on Soviet design principle, core technologies, important subsystems, layout, and other expertise that were difficult for Chinese to obtain, and these valuable knowledge would later help China in designing its next generation replenishment ships. The most important gain, however, was financial. The original funding that was insufficient to develop a proposed indigenous 2nd generation Chinese replenishment ship was not only enough to buy the uncompleted former Soviet ship, but also had enough left to cover the following conversion work. One of the primary areas of improvement of the original former-Soviet design was in damage control, which was woefully inadequate (Rumored due to its original civilian merchant tanker design). Some of the interior wiring was exposed, and the ship's battle damage control system was very limited, with a near absence of internal damage limitation, insufficient fire-suppression system and water-tight locks. Incorporate the experienced gained from the rework of Type 053 frigates exported to Royal Thai Navy, the damage control of the ship was upgraded to western (mostly German and American) standards.
