There I found three examples where holes were cut through the hulls of ships to remove or install something. I think it's pretty standard stuff and they will simply pop the pieces back and re-weld it.

Well that's the point I'm getting at -- it's standard during extensive refits or MLUs or ships, but not something you do everytime a ship enters port. That is to say, cutting holes in is a standard procedure for medium term to long term refits for a vessel when you're looking to replace something in the ship that cannot otherwise be accessed, but not something anyone would do on a whim.

I have been a "firewatch" while cutting a hole in the hull below the waterline.
It was done faster then i thought.
They used it to replace a drinking water system.

But i have never seen holes being cut while in the harbor afloat.
And not one of them had a platform with railings made.
Plus even if they where there. Acces would be denied when not in use. Wich is done at the chinese.
Also why 2 holes exactly the same on the same level connected with an hallway.

I know its crazy to cut holes for pauses. But it was just an brainfart haha.

To be honest I've never seen holes cut and the railings there as well and cut in such a manner HOWEVER with all that being said I'm also 99.9% sure it wasn't cut so the workers could take a smoke break either :)
Cutting holes is not a big deal and I'm sure it was cut to facilitate the insertion/extraction of old/new equipment. Railings/platform were probably just welded there as an afterhought so workers CAN hang around smoking and shooting the breeze.
That IMHO is probably what happened.

With no power thus no effective ventilation in the room where the holes are cut you run the risk of inhaling hazardous air which could be bad for your health.

And unlike doing the same task on land, you can not just walk out to have fresh air unless you like to have a swim. Thus a resting area for fresh air in the shape of a simple platform is only logical.

Well during dock times the Dutch ships still facilitate electricity and external ventilation is being provided.
But a lot of times it is to few and it gets hot and smelly. So its a cheap and good idea to make these holes indeed.

But China does everything different. So we can only speculate.
Also the fact that these holes are open and no door/slap of cloth (coulnd find the word haha) to keep nature outside is weird to.
You dont want salt air and insects in the ship.
The citadel provides a handy defence system on that issue haha.
I like sailing in warships. No nasty insects like silverfish or spiders or ants.

We see no covering for the hole at the moment the photo was taken, I would be surprised if it was left open to the elements 24 hours a day. Likely it is only open when there is relevant work to be done at that particular part of the ship.

And I'm not sure why we're assuming there is no power for ventilation during maintenance. We do not know the extent or type of maintenance so we don't know if the relevant powerplants are affected (or even if they can't bring in external auxiliaries). More importantly, what kind of job would they be doing that might cause hazardous fumes, and wouldn't a simpler solution be to make sure there is ventilation when such maintenance is needed, and to give the workers respirator masks instead, rather than cutting a hole in the ship that then needs to be sealed?

I'm going to apply occam's razor here and say the hole is for replacing internal equipment. It's common for holes to be cut in ships, yes, but more often than not it is for replacing internal equipment that cannot be replaced in another way.
The other options are possible but they seem far too contrived.

Chinese citizens visit the recently upgraded guided missile destroyer Harbin, 112, of the North China Sea Fleet which was opened to the public in east China's Shandong province to celebrate the PLAN's 66th anniversary.

You can see the new starboard side Type 730 CIWS back there, along with other modifications. Nice.
