My thought too, but I wasnt sure whether I am just making too much out of the dimensions.
At this point its hard to say whether its a 052D or a 055.
I don't know exactly what it is, but I can fairly say it's not a commercial ship as the commercial ships built by DSIC are expected to be much bigger. So big, two of them will fill up the dock abreast and will reach all the way to back. This drydock is originally meant to build two supertankers side by side. Commercially, DSIC has leaned towards building large boxships, tankers and FPSO, and those modules are way too small for these.
