Thanks your various replies.
"Jinhae" - forgive my ignorance - I just searched for yard beginning, and yards at, "Jinhae". IHC list it as "STX Offshore & Shipbuilding Co Ltd - Changwon (Jinhae Shipyard), at Changwon", so it just didn't surface. I didn't see STX mentioned here at the time.
I think that gross tonnage often appear different on orderbooks. It tends to be the round figure given at the time of the order being announced/revealed initially, but of course that changes to a precise figure as ship are completed and official certificated issued. MSC ELMA/PALAK are listed as 96816gt, and no doubt the following two can be expected to change to something similar, if not identical. Does that sound plausible? All four are same 300m length.
Of the following 11 there do seem to be two sizes: Yd 233/234/235/238 are listed as 314m; the other seven as 328m, which looks like one row less.
As I noted before, this is IHC data, other sources may differ, and changes may not have been noted there or elsewhere. And I'm not as close to the real business as many of you.
Address of yard given as "No.1 Jinhai Street, Changtu, Daishan, Zhoushan, Zhejiang, 316291":
