But this guy said the 055 coming back to the ship yard , he said in Weibo: 试航回来的小火车.

A little bit of next to useless calculations:

Displacement of the ship in those images may be 2000 tons below max displacement, *if* max displacement is where red painted part of the ship ends. (actual draft marks on the stern actually go a bit over the line, so it may be more)

Method reaching that figure was this: rough approximation of area at waterline, comprised of one 19*100 m rectangle and one symmetrical triangle with 19 m base and 65 m height. Times 0.8 meters height of visible red area above current water level. 0.8 was approximated from people height on the stern, assuming 1.75 m height. Yeah, it's all quite rough and probably not very accurate but what the heck. One unanswerable question would be how much extra displacement over empty ship displacement does the vessel have in those images. It probably isn't carrying a lot of fuel nor a lot of supplies, nor does it probably have a large crew onboard.

(if max displacement is at the waterline level of highest existing draft mark, then there's room for 2400 tons over whatever displacement ship enjoys in that image, as marks go ~110 cm over waterline)

It also seems to be an unusually low slung warship, an impression enhanced by having no distinct stack.

The gun turret could be better integrated into the ship’s overall scheme of stealth facet angles.

Only appears low slung because the hull form has a very high freeboard and blended superstructure and its length masks the bulk of its forward superstructure. If you fill in the space between a burke's stacks, give it an integrated mast add a 100ft of hull after the stacks it would probably have a similar profile, be interesting to see it next to a RN type 45 destroyer which has a really tall forward mast in order to gauge it's height and bulk

Won't be carrying any munitions, helicopters/drones and associated supply chain (fuel, weapons spares etc) that's easily several hundred tons (using an even 2 tons per VLS tube that would be 224 tons already without factoring in anything else!) and if the pictures are of its homeward leg a reduced fuel load, if there's suitable images of her on the outbound leg then you'll have 2 data points regarding fuel for comparision. But on a absolute displacement basis can't really derive a great deal as she's likely to be ballasted
