Looks like the refurbished drawworks from Deimos was spotted at Roberts Road during a September 2022 flyover.

So the rigs were bought since it was the cheapest way to get the winches to shore?!

You're joking, of course, but I'll remind everyone that SpaceX did get these rigs at fire sale prices, literally pennies on the dollar.  The oil market collapsed in early 2020 at the beginning of the pandemic, and oil prices went to approximately zero, or even negative (couldn't give it away).  Big Oil slammed the brakes on exploration and extraction, oil rig operators got desperate, and Elon took advantage.

I wonder if they made money on them ...

PSA #1: EST does NOT mean "Eastern Time".  Use "Eastern" or "ET" instead, all year round, and avoid this common error.  Google "EST vs EDT".
PSA #2: It's and its: know the difference and quietly impress grammar pedants.  Google "angry flower its" .  *** See profile for two more NSF forum tips. ***

Were they going to do the engineering for the platforms in house, or outsource it? I assume that there's only so many firms that have the experience to make the plans to modify the rigs, and even fewer that can make plans to launch the largest rocket in the world from one. In my industry there are projects that come along that nobody wants to touch.

As part of the refit, the upper portion of at least one if not both semi-submersible platforms was removed. Outside of the winches, I suspect much of the equipment that was removed might was sold - either for spare parts or as scrap metal.

Taking into account those early sales, the costs related to the aborted refurbishment, as well as the sale of the platforms themselves, I suspect SpaceX might have paid less than market value for the winches taking into account their condition when the two platforms were purchased by SpaceX.

The former SpaceX-owned Deimos rig appears to have finally got underway from Pascagoula, under its new ownership.

The towing vessel has a reported destination of Nassau, Bahamas.

This may be of interest

I have a theory about why SpaceX may not be interested in a sea-based launching platform for their SuperBooster and StarShip.

During the booster's first launch, it caused significant damage to the launch pad due to its intense power. Is it feasible that the water underneath a floating oil derrick launch pad could be disturbed to the point where the platform loses its buoyancy and sinks?

It's worth noting that Sea-Launch utilized a flame diverter to address this issue, but the thrust of that rocket is not comparable to SpaceX's.

SX sold Phobos/Deimos long before the first Starship-flight.
Besides that, the whole idea of pointtopoint Starship-flights is heavily based on sea-launch.

 Elon actually said in 2019 that they were only planning sea launch for p-p.

Maybe because p-p sea launches are without the booster?
Other 6 engines and other 33 engines fired!
