While I was taking the picture above, three different cars of people pulled into the parking lot and took cell phone pictures.

That still indicates celebrity status to me, even if it is only rocket geek celebrity.

All three were sets of young folks. Warms my heart

I wonder if Fishlips has seen any appreciable increase in business since SpaceX has started using that berth?

Quoted from the Fairing thread:

Wonder what a "short term opportunity area" means...

If I remember correctly, someone up-thread said this would be used for storing previously flown Falcon 9 boosters.
I think you're thinking of the 35000 s.f. of land and 77000 s.f. of water that are being added to SpaceX's permit near berths 51 and 52. In any case, we will see later this month what happens to the B1036 booster with the Iridium NEXT-4 flight.

Quote
Backqround: On January 7,2016, the Board approved RP 15-19 to SpaceX for the use
of 35,000 s.f. of land and 77,000 s.f. of water at Berths 51 and 52 along Miner Street in
San Pedro. RP 15-19 allowed for: berthing rights for the Marmac landing barge and
auxiliary vessels; construction of landside improvements including the installation of
rocket support pedestals on a concrete pad; and installation of temporary perimeter
fencing, an office trailer, a guard shack and portable restrooms. SpaceX's premises are
utilized to berth vessels that recover expended rockets and capsules from over 100
miles offshore and return the respective equipment for land based transportation to
various locations.
ln response to the Board's concern regarding insurance limits and coverage under selfinsurance,
the First Amendment to RP 15-19 increased insurance requirements to
provide superior insurance coverage, thereby reducing the Harbor Department's
financial risk exposure arising from SpaceX's operations.
The Second Amendment to RP 15-19 increased permit premises primarily at Berth 53
and adjusted compensation correspondingly. The additional areas provided SpaceX
with access to a wider area such that it can conduct its operations more safely and
efficiently, and also reduce the length of time that Miner Street is shut down, thereby
lessening the impact of SpaceX operations on neighboring tenants. A provision was
also added to allow the Harbor Department to be reimbursed for expenses incurred as a
result of the Tenant's operations such as Port Police fees (escort, street closures, etc.);
Construction & Maintenance costs (placement of k-rails, plumbing and electrical
services, etc.); Engineering fees (inspection fees, etc.); rental fees for use of additional
areas (staging for media, parking, etc.); and other related. costs.
SpaceX has conducted five rocket and capsule recoveries since 2016. On November
15, 2017, SpaceX submitted an application for additional premises in order to
accommodate the MA/ Mr. Steven, a 205-foot long vessel dedicated to recovering the
fairing portion of rockets which protect the spacecraft and reduce drag during flight.

No additional hazardous materials will be brought to the Port. The extended area will
allow a better layout for its operations and allow SpaceX to remove equipment on top of
their sea vans as much as possible, and better contain their equipment behind the
perimeter fencing, away from public view.
The proposed Third Amendment (Transmittal 1) to RP 15-19 modifies the permit
premises by adding a9,143 s.f. land parcel and a 25,500 s.f. submerged land parcel on
the south side of its current premises (Transmittal2), and modifying the compensation
accordingly, from $24,328.73 to $28,095.82 a month. ln anticipation of the vessel's
arrival in mid to late December 2018, SpaceX would like to take possession of the
additional premises by December 15, 2017.

According to Marine Traffic, Mr.Steven is now at the berth in Port of Los Angeles (adjacent to NRC Quest, which has been used by SpaceX for F9 and Dragon recoveries), presumably preparing to go to sea to try and recover the Iridium fairings.

On the east coast, Elsbeth III is in the Gulf of Mexico; and Hawk is in Tampa - both a fair distance from Port Canaveral. That said, there's probably at a month until a tug is needed to drag OCISLY out to fetch an FH centre core.

The Go 'twins' are both at Port Canaveral.

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?   :)

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?
