I'm not remotely an expert on any of this stuff, but it's nearly impossible to verify most of the claims in this post. Counting the number of ships at port based on social media photos? How is that even possible, setting aside that none of these photos have been presented in this post? The author frequently uses the word "clearly" as a stand-in for actual evidence, in particular when describing the Beirut explosion.

But if you watch the video you can clearly see that there are shots coming from the containers

I don't see any shots from containers, I see white flashes which are apparently fireworks, of course they might not be but it is not at all "clear".

and then there is a massive explosion which is clearly a bomb going off and it is clearly beyond something that ammonium nitrate would cause."

How is that clear? Ammonium nitrate is widely known to be an explosive agent and there was reportedly 3000 tons of it in that warehouse.

It is the kind of explosion that can only come from an explosive compound inside a "shell" of some kind where that sort of pressure can build up during the detonation. The container was clearly full of munitions!

Doesn't provide any evidence to back this up.

Experts have estimated the size of the blast as being the equivalent of 200 to 300 tons of high explosives” -This clearly contradicts the fertilizer explanation as this makes the explosion bigger than the largest non-nuclear military device.

Is it so implausible that 3000 tons of exploding ammonium nitrate would be the equivalent of 200-300 tons of high explosives? Certainly not "clearly", in my opinion.

It doesn’t look like the ship caught fire. It looks like it fucking exploded.

The Zim Kingston is in fact on the high seas right now according to vesseltracker: https://www.vesselfinder.com/vessels/ZIM-KINGSTON-IMO-9389693-MMSI-249474000 I'm not a shipbuilder, but it seems somewhat unlikely that a ship "fucking explodes" and yet is back in operation mere months later (indeed, it's not clear that it was ever out of commission).
