During the mission, Lanzhou sailed more than 40,000 nautical miles and 4,280 hours of navigation time.

In May 2014, the China National Offshore Oil Corporation drilling platform Offshore Oil 981 was drilling in the Xisha waters. Due to the disturbance of Vietnamese vessels, Lanzhou was dispatched along with China Coast Guard cutters to expel the Vietnamese vessels and guard the drilling platform.
