Yes, but that was four years ago, in 2007. There appears to have been no interest in 515 and 517, which were decommissioned at Ningde late 2010.
Strictly speaking, 509 (1002) and 510 (1003) were not the first, but Hulls 10 and 9 respectively.
515 was Hull 2, 517 Hull 3, while Hull 1 is 516, which was converted into a fire support ship.
At this point in fleet modernization and the rate the shipyards are cranking out new hulls, I doubt they want to repurpose these older hulls for use within, mostly because of pride in my opinion. I could see retrofitting them for CG duty for other nations as gifts being a worthy PR tactic, much like the US with their gift of a refurbished USCG cutter to the Philippines.
