    You would need to build a watertight cut-off wall surrounding your site which extends all the way underground, since marine deposit is generally permeable and water can seep under an embankment and up through the excavation. This is doable but not always easy as concrete may crack due to various workmanship reasons.

    Then you need to excavate by stages with an elaborate excavation and lateral support design, and the excavated materials have to be transported away. The ELS will often pose constraints to your plant access which makes it more difficult and hence slower to excavate by large machinery. Also it is way easier to mug out by barge than by land transport due to the excavation volume and logistics involved.

    Afterwards you need to demolish the temporary cut-off wall which is not only difficult to remove but also a massive waste in construction materials.

    All in all, it's much simpler, faster, cheaper and more sustainable just to do it by dredgers.

    That basin close to 1km long, and 400 meters wide.

    All USA carrier would fit into it, and there would be still place left for the lock and enough area to build two carrier .

    Are they going to build container ships in that dock as well?

    It is a basin, not a dock. I guess, it is for military ships only.

    Others have already pointed it out, but I can't help but chip in too. What you described sounds even in so few words sounds many more times more difficult and resource consuming than doing the dredging that they've done instead.

    We don't know the purpose of it.

    It can be divided into different segments later on.

    thanks for the in depth explanation. if the soil is indeed that porous dredging is definitely the way to go. and the fact we are seeing the area bring dredged means the area is likely too porous.

    anyway, I guess then we don't know what the scope of dredging and work will be, later on.

    though, if they wanted to build a dry dock, I still guess they could have dug that up earlier and sealed it off from the ocean water pouring in through the soil.

    I suspect it all means that this area will only have shallow draft boats on it. And if all you're going to do is bring in and load barges with carrier modules, that's all you need. Those type of vessels don't need the type of basin you would normally associate with larger ships.

    Rumor is that the new production section will build two 002 (non-nuclear,emals) carrier consecutively. And a nuclear one at Dalian shipyard later.

    I'm skeptical on building two 002 at Shanghai, but I will be happy to see if this is true.

    few interesting question
    no 1
    what they wants to do in the area empty next to the current assembly ? It is a prime assembly area, with easy access to all facility , and with direct access to the basin.

    Second, why the current supermodule building area is not next to the shore, shown as bellow ?
    That should make the required size of the basin smaller, and the movement of barges would not disturb any other activity in .

    I don't think that anyone can answer it, it is more of a highlighting of interesting aspect of the design.
