To bring the loop ever closer to closing, it seems that Signet Warhorse was the Tug used to deliver the rig to Brownsville.

I'm happy to be corrected, but I'm pretty sure that SpaceX have used Signet Warhorse a number of times in the past few years too.

Seems a bit much to become the richest person in the world bankrupting the fossil fuel industry just to get a good deal on bankrupt oil stock.

But $3.5 million a piece is a damn good deal.

Based on sentinel 2 images it looks like the work tents were put up in September 2020.

This is a great bit of sleuthing by Jack Beyer and then followed up by Michael Baylor and others.  Kudos.  Top notch.

It looks like at least Deimos is being converted by the American subsidiary of the same company that built it in the first place.  I thought SpaceX did all it could to hollow out that company of good welders in Brownsville, but maybe there are a few left.

Main Deck elevation above baseline:  97ft
Rated Max. Water Depth:  8,500ft
Moonpool Opening:  30ftx 120ft
Variable Deck Load:  8,000 T
Cranes:  (2) Seatrax 160ft boom, 97 T
Thrusters:(8)  Flowserve-Pleuger Azimuthing, 3,500 hp each
DP Class:  DP-2
Accommodations:  150 persons

Here's a Taxes Railroad Commission case where Lone Star Mineral Development LLC bought or leased a gas well (LA PITA (GAS ID NO. 264705) LEASE, WELL NO. 3, not sure if it's the one in the old gas well site). The officer for Lone Star Mineral Development LLC is listed as Johnsen, Bret, who is of course SpaceX's CFO. This confirms Lone Star Mineral Development LLC is indeed a SpaceX company.

It does not look like the BC gas well site to me, here is a link to previous discussion about those wells

It's the disposal well.

Ah. I was looking at gas wells and missed that. Maybe to dispose of brine from desalination of brackish well water?

Edit - Further discussion of this well probably belongs on the manufacturing facility thread next door

2 things I've discovered of note, one is rampant speculation: 
 
1. A road connecting highway 4 (which runs through Boca) to the port of Brownsville is under construction. This road comes out right near where the rig is.
 
https://www.portofbrownsville.com/construction-begins-for-south-port-connector-road/   
 
The rig is just off to the right in the image provided in that article. 
 
2. I couldn't help but notice this large, flat decked barge right next to Deimos. It looks like a whole bunch of other barges welded together to make one, massive, flat surface. It even looks like the gaps were recently filled in between the pieces. Is it possible that this is ASOG? I'd have no idea how to check who owns it.
The 'big barge' appears to be Keppel AmFELS' floating dry-dock.

It looks like Sir_Bedevere was spot-on, by the way.  The conversation back in June has fresh relevance.

There are also Injection wells around to fight saltwater intrusion into the freshwater aquifer. Not for sure what its registered use is though.

So the parent company Keppel along with Kværner ASA I'm hearing might have a consortium contract (might still be in finalization) with LSM for construction and engineering services. Kværner ASA whose predecessors converted the LP Odyssey for Boeing which purchased the platform for Sea Launch.

Note the composite barge (appears to be named Solomon P. Ortiz), while nearby to Deimos, has not (yet) been associated with it. It is moored attached to an unrelated vessel, and owned by a still operating company. Deimos is moored in Keppel AmFELS' dock though.

Plus the Rail Road Commission of Texas RRC case documents for hearing to change name of operator from DALLAS PETROELUM GROUP, LLC to LONE STAR MINERAL DEVELOPMENT, LLC records cite emails to SpaceX employee email addresses.

Hey, has Liberia signed the Outer Space Treaty? ;) (I’m kidding, of course...)

EDIT: Hmmm... no, they haven’t!!!

Note that the flag of registry was made Liberia by the previous owners, fifteen years ago.  Whether the current owner chooses to re-flag it is a different question. ;)

"deck load" is 8000 tons, I guess that is ball park for a 7500 ton launch vehicle?

Sailing under Liberia flag is common to avoid regulations and such.

250x250 is the size of the SpX landing pad for reference

SpaceX bought two former Valaris oil rigs to build floating launchpads for its Starship rocket
PUBLISHED TUE, JAN 19 20211:22 PM EST
Michael Sheetz
@THESHEETZTWEETZ

KEY POINTS
Elon Musk’s SpaceX bought two deepwater oil rigs last year and is converting them into floating launchpads.

Public records show that Valaris sold rigs 8500 and 8501 were sold for $3.5 million each in July, shortly before the offshore rig company filed for Chapter 11 bankruptcy.

The rigs, renamed Deimos and Phobos, are in the Port of Brownsville near SpaceX’s Starship development facility in Boca Chica, Texas.

Article includes:

Quote
SpaceX’s purchase and work on the oil rigs was first identified by reporters for NASASpaceflight, a space-focused website.

The company did not respond to a CNBC request for comment.
