So there are two water circuits and a cold/liquid nitrogen circuit.

It seems like one of the water circuits connects with the nitrogen circuit, possibly making a kind of snow maker.

I can understand using nitrogen to displace oxygen for fire suppression, adding some water will help a little but mostly it helps cool stuff. But if this is a fire suppression system what is on fire in there that needs to be put out?

Excluding methane, there's not a lot of stuff that should burn under the rocket, there's probably a lot more burny stuff bolted to the sides but we are not seeing any fire suppression there. If it's out of control methane burning you have a really big problem that I doubt that fire suppression system could handle.

So it doesn't make sense to me that this is just for putting out a fire. BUT it does seem like it could absorb a lot of heat energy, maybe it's a cooling system for static fires and launch?

They don't think they need a deluge system for sound suppression or flame diverter because they designed the rocket to be robust etc. But all that heat is going to be too much for the structure and equipment down below and nearby. So maybe this is just a big air-conditioner! 🤔

Here are pictures of the blast damage from the 7 engine static fire.  Before, and after. 

So with zero deluge 7 engines causes some amount of damage.
I see no 'blast damage', just intumescent paint doing its job and charring as intended.

That's a lot of aerosol and not much liquid water.  Probably shouldn't call it a "deluge".  Look at the slotted curb line below the mount on the edge of the pad.  No visible runoff there.  This is nothing like a rainbird.

(1/2) If you have been wondering why there have been 30+ workers on the Orbital Launch Mount with Sparks flying everywhere 24/7 over the last few days. The reason is because they are installing additional blast shielding to protect the interior of the structure.

(2/2) Hey #StarshipAddicts, here is a preview of @RyanHansenSpace's animation showing one of the OLM upgrades currently in progress. These large plates prevent explosions from entering the table through the side of the hold down arms.

This upgrade is a top priority. #B8CanWait

Booster 9 and the Orbital Launch Mount Upgrades | SpaceX Boca Chica

28 Sept 2022

Booster 9 has been stacked on its engine section, with the notable lack of HPU covers, and the Orbital Launch Mount continues to be upgraded to support Starship's orbital test flight.

Pretty good.  Worth the watch.  His analysis of the changes they made to the water and nitrogen lines under and around the launch mount is quite informative. 

He's also made sense out of why they're doing it differently in Florida.  Where they have more water and a catch basin.

Edit for clarity.

How far are they along on the orbital launch mount upgrades?
