I Think that might be it, on a Arleigh burke video I found on youtube, they have a couple of normal single watertight doors then one of these:

But from a cursory glance at various videos, they don't seem to be especially common.

Arleigh Burkes don't have many airlocks with double doors because only a limited number of compartments and internal spaces are designed for total CBRN protection. The same is true for all other naval ships I can think of.

I think your third from bottom photo shows double watertight doors.

I think I finally understand what Xavier meant by "double watertight doors". The proper term is

, and as my previous post shows, 052D in fact has airlocks as part of its CBRN/NBC defense system. What remains a mystery, though, is how Xavier doesn't recall seeing them when he undoubtedly came across them on his tour.

From Wikipedia:
An airlock, air-lock or air lock, often abbreviated to just lock, is a compartment which permits passage between environments of differing pressure or atmospheric composition while minimizing change in pressure and mixing of environments in the adjoining spaces.

An airlock consists of a chamber with two

doors or openings, usually arranged in series, which do not open simultaneously.

So I reread Xavier's podcast transcript in light of by78's very informative posts. Some breakdowns:
And while touring the ship, I could not help
but notice compared to other vessels I'm used to tour now. So European frigates or even the
US Navy destroyers and so on. What really stood out to me was the lack of firefighting and damage
control equipment inside the vessel. It was very, very strange.
This is a blatant lie contradicted by video evidence.
And now I pay attention to those
details whenever I visit a vessel. And now, I mean, the more I pay attention to it, the more I
realize that the Chinese destroyer was very different. For example, there was walking from
the helicopter deck to inside the vessel. There was only a single watertight door. The second
door was not watertight.
The RHIB compartment has a single watertight door because this compartment is separated from the environment with only one layer of the roller shutter curtain. On the Arleigh Burke class the RHIB is stored externally so there are no equivalent compartments.
I was lucky enough to tour USS John Finn in Japan probably three weeks
after touring the Chinese landing destroyer. And I really felt the difference between USS John Finn
and that Chinese destroyer. Other things that really stood out was that they were storing a
vessel inside the ship with gas tanks next to that small boat.
There does not appear to be gas tanks next to the RHIB in the video, although Xavier may have confused various cylindrical objects with gas tanks on his tour.
And a few feet ahead of the small boat
was the triple torpedo launcher with no separation whatsoever between the fuel tanks and the torpedo
launcher, no damage control equipment, nothing.
This is a blatant lie contradicted by video evidence.
Walking from aft to the front of the ship, I
could not find any kind of watertight door inside the vessel except the watertight door at the very
after and at the very front of the vessel.
This is a blatant lie contradicted by video evidence.
I mean, again, very, very surprising. And
like I said, I've toured the Japanese FFM, I've toured the Italian PPA, heck, I even toured the
South Korean built frigate of the Philippine Navy. And they all featured double watertight doors,
pressurized atmosphere, controlled atmosphere, and so on.
The Type 052D features pressurized controlled atmosphere but this is probably due to Xavier's ignorance rather than conscious lying.
And none of which I found on the
Chinese destroyer. So that's very surprising. I don't know what your opinion is about this,
but maybe that's why the Chinese managed to build in such large number. Maybe the quality
of the vessels is not there. I mean, I'm not a naval architect, but it's just what I could observe
while touring that Chinese destroyer.
Yeah, not a naval architect indeed.
Absolutely. Yeah, I mean, totally. And
I guess what they were missing for firefighting and damage control equipment inside the vessel
was compensated by loads of propaganda. They had all sorts of posters and even like LED
lights, displays with like, you know, typical like communist propaganda. I asked one of our
escort for like a translation and one of the signs said something along the lines of,
"No matter how far you're sailing on the seas of the world, never forget who you're fighting for,
for motherland China." Okay.
If Xavier made it to the living quarters where the posters are located he would have past multiple damage control stations/watertight doors.

What I can conclude base on his claim to have traveled from the aft to the front of the ship is that Xavier would have necessarily passed through so many watertight doors and damage control/fire fighting equipments that would be impossible to miss all. Thus his claims must be deliberate lies, unless he suffer from memory loss or visual impairment.

Let's keep things above board.

Unless there's evidence of deliberate falsifying of information or outright lying, I think we shouldn't automatically assume malice. Hanlon's razor applies here.

For a complete novice like me, the watertight doors in these videos (with round corners, some painted brown, some white), look somewhat similar (stressing the somewhat) to the non watertight doors (with square corners, mostly painted brown); especially when compared to a western watertigher doors which are much more oval (told you I am a novice).

This is my long-winded way of saying I agree with Blitzo's advise of givng Xavier the benefit of the doubt; that Xavier may be more of a naval novice like me, despite him running a naval news site :)

Ciao.

Welcome to the board, Xavier!
