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.

The application is being handled by Rachel Lovejoy, a lawyer for SpaceX who is usually in charge of intellectual property issues.

Was waiting eagerly for this news. Seems like the last big piece of the puzzle. Obviously a LONG way to go on many parts of the project, but I think this puts all the pieces on the board.

No that drill ship arrived in Brownsville already three years ago, supposedly to be scrapped:

https://www.portofbrownsville.com/wp-content/uploads/2017/01/12-12-2017-1.pdf

It has an interesting story. I was built in the Netherlands and started as a freighter. Then it was converted to a drilling ship in Japan. 4-5 years ago it was part of a company called Paragon, which entered chapter 11.

It's probably unrelated, but a drillship _could_ make for an interesting next-gen landing platform. They're designed to be (relatively) fast when underway, stable when drilling, and usually have very good dynamic positioning systems.

I love the lean, cheapskate operations of SpaceX! They basically got those oil rigs for free, just as they have scrounged so much other hardware basically for free, huge tanks, etc, etc.

Elon (now the worlds' richest man, remember) is pushing through a company ethic completely different from that seen in bloated legacy aerospace companies. Seemingly very different from that seen at Blue Origin too. He keeps his staff on edge, "hungry" almost, and that's why they perform so much better. If you are not under limitations of time and money you will never work effectively.

- Regarding the names of the rigs, I wonder whether the fact that they were given "serious" names, contradicting the usual flippant SpaceX nomenclature, indicates that they will indeed play a crucial role in Starship operations. I'm thinking launches and not just landings. However, are we SURE that they will be launch platforms? Any confirmed info out there?

This is the way God and Robert Heinlein intended the story of the Conquest of Space to go.

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.

Don't be ridiculous. The .1% of cars out there that might be Tesla has nothing to do with it. The only way Elon Musk had anything to do with Valaris' bankruptcy is if he started the coronavirus.

“The substantial downturn in the energy sector, exacerbated by the Covid-19 pandemic, requires that we take this step to create a stronger company able to adapt to the prolonged contraction in the industry,” Valaris Chief Executive Officer Tom Burke said in the statement. The company plans to continue serving customers uninterrupted throughout the bankruptcy, he said.

The price of US oil has turned negative for the first time in history. That means oil producers are paying buyers to take the commodity off their hands over fears that storage capacity could run out in May. Demand for oil has all but dried up as lockdowns across the world have kept people inside.

A lot of the equipment is irrelevant (and might be removed /inoperable anyway) but some basic stats from here:

Pontoons:  310L x 56W x 24ft
Columns:  (4) columns, 45ft x 50ft
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
Lifeboats:  (4) 75 person

Deck size is 240' W X 250' L.  Easily big enough to land Starship/SH orbital boosters and flight stages.

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

Fully fueled vehicle is just a couple hundred tonnes north of 5,000 tonnes so no weight problem

From another site:


There is a Mars basin in the Gulf of Mexico that includes an area named Deimos that has been producing oil since 2007. Very likely that rig has worked that site.

About the price:
Quote
The average cost for offshore rigs can be as much as 15 to 20 times greater than the average cost for land rigs. The least-expensive offshore rigs typically cost nearly $200 million. The average price for offshore oil-drilling rigs is approximately $650 million.

It's possible that earlier builds were somehow cheaper but ENSCO paid Keppel $560 million in 2008 to build 8506... A very solid 99% discount for SpaceX.

Deimos, one of the oil rigs SpaceX is planning on converting into a floating Spaceport, as seen from the air today, 01-19-21. Its name has been painted on the helipad and lifeboats, so cool. @elonmusk @NASASpaceflight

Its going to be wild to see this behemoth transformed into a rocket launching seagoing spaceport. I have so many questions that only time can answer. @NASASpaceflight

Wild speculation:
Yellow bridge crane for sale... or maybe the missing bridge crane for the highbay?

Formally introducing the two newest members of the SpaceX fleet: Phobos and Deimos.

Photos of Deimos from @thejackbeyer for @NASASpaceflight. Extensive research for this story by Michael Baylor (@nextspaceflight), written up by me.

There are three other 850X platforms in Galveston Bay right next to Phobos. At $3.5M each all 5 would be a price of $17.5M. Has anyone checked on the ownership of these three other's? In July 5 platforms were sold 2 of which were Deimos and Phobos. ???

Did any body else notice that the azipods are being stored under the red and white cranes? Four on each side.

Does anyone think it might be possible to use one of these as a downrange landing platform? Launch from Boca Chica and land a few hundred Km downrange like they would a droneship, so they can increase the payload to LEO?

Great news!
I found a report showing how the ENSCO 8500 platforms were constructed. It contains some photos of the construction phases:
