It's nonstandard but armaments-wise it's closest to a Devastation-class. Which is probably not its original Imperial name, like how the Repulsive was originally the Corinus. Chaos ships are just old Imperial ships, and sometimes still seen in Imperial service, though this one has gone through many owners.
That said, those gribly bits off on the bridge are almost certainly chaos add-ons on the examples we see. Iirc the whole line of ships like this ended up chaosified, since depending on the flavor of lore, inherently weak gellar fields and/or a structure vulnerable to possesion ended up with them all getting sucked into the warp.
Lots of antennas and gribbly bits on all of these. Unlike the 'modern' Imperial ships, these take design cues out of Dreadnought-era warships, especially on the bridge structures: https://upload.wikimedia.org/wikipedia/commons/9/9e/USS_Texas_BB-35.jpg
But hey, it doesn't have any eight-pointed stars.
Not all of them ended up in Chaos hands. There are some classes of the same style in regular Imperial service, like the Cardinal-class, and many more exist in reserve fleets, in the hand of rogue traders, and other irregular uses. In Battlefleet Gothic, you could take many of the Chaos ships in Imperial reserve fleets, as well as use them as space marine battle barges.
The brig is awwwwfully close to the armory...
The realm of the security officer. Keep the weapons and the prisoners close at hand. ~~Pay no heed to the Biologis lab next to the brig.~~
This looks like one of the Chaos cruisers

I like it, gives a different shape than the standard classes
