Seems to me that elsbeth III has been released from SpaceX exclusivity and is now free to take other jobs.  Towing the ASDS is apparently enough of a "standard tow" that they can use whatever tug happens to be free.  Seems like a minor operational refinement to save a few bucks.

It does look like SpaceX aren't using Elsbeth III, but it will be interesting to see if they persist with Hawk or switch between tugs depending on availability.

The speculation has always been that eventually the ASDS could self-propel out to the landing zone, so it would only need a harbor tug.  That hasn't happened yet. So there's a spectrum of possible tug requirements ranging from "harbor tug" to "any ocean-going tug which can handle a barge" through "some unique handling requirements and training, so we like to deal with a small number of tugs which have prior experience with ASDS" to "custom SpaceX gear must be installed on the tug and is troublesome to move between tugs".  So, yeah, I'm also interested to see the continued evolution of who gets to tow the ASDS, and how far.

For a myriad of reasons, some technical, some legislative, it ain't ever going to happen. Never.  Not without a complete redesign of the thruster arrangement and a re-classification of the barge to somewhere they (and the barge owners) won't want to go. :)

...still and all, AIUI and IIRC, their main reason for retaining the services of EIII was they had a short-term exclusive lease agreement to use her and her people for this and other support roles.  Perhaps that agreement has now expired and they're free to do as they wish?  After all, apart from the extensive experience of the crew (no doubt necessary during the working-up stage), there's nothing particularly special about that tug...

With sufficient thrust, pigs fly just fine - however, this is not necessarily a good idea. It is hard to be sure where they are
going to land, and it could be dangerous sitting under them as they fly overhead.

Looks like Mr Steven is sporting the Guice Offshore logo now.  So is it "GO Mr Steven"?

Go Mr Steven!

Wait, GO stands for Guice Offshore?  Does OJ know?   :)

looks like that guy on the new upperdeck is drilling holes through that diamond plate into the cross beams with a mag drill

There is a ZF cardboard box sitting there. looks like they make boat thrusters. wonder if they are adding or fixing some for finer dragon recovery control.

edit: looks like they make a whole lot of other stuff for boats too, so could be anything

its funny i think they also make the electric motor winding maching for tesla

ZF is a common marine transmission manufacturer. I have ZF transmissions on my twin Cummins 380 HP QSB 5.9 diesels.

What guy?
What drill?
Upper deck?
I donít even recognize the ship.
I think I see two people conversing.
Can you explain more what you see?
What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

So... The roof they were building on Go Searcher is complete (and level, not tilted), and there's a plastic wrapped box sitting on top now?

It seems clear to me these are modifications for dragon recovery and either cargo or crew unloading and storage. You can see the cutout on the aft of the new platform where they will slide dragon up to it.

They installed a lifting A Frame on the stern - the kind used to retrieve submersibles. Iíd say Dragon recovery is a good bet. But question - what are they using now for D1 recoveries?

Yes. Dragon recovery has migrated through several recovery vessels on the west coast. The most recent being NRC Quest. Seems clear that they are looking for a east coast recovery ship. Either for crew or cargo. If not for primary landings then for aborts or weather contingencies.

I guess the Sea Stallion helicopter went the way of the tractor escape tower.
But arenít we off topic for this ASDS thread?
