SpaceX Purchases 2 New Ships: Bob and Doug
« on: 08/11/2021 06:32 am »
New scoop from Space Explored says SpaceX has purchased(!) 2 new ships, naming them Bob and Doug. They've already been given spiffy new paint jobs. Presumably they'll be used for fairing recovery

We don't actually know what these two ships are for, so I think they warrant their own thread. If it turns out they are indeed for fairing recovery, this thread can be moved.

I can confirm that SpaceX is building two brand new ships.

Bob and Doug are designed as an all-purpose solution to tow and support droneships offshore and also recover fairing halves.

The ships have been under construction in Louisiana since May and are due in Florida very soon

Quote
A large winch can be seen underneath the new raised platform which is designed to tow droneships at times when they cannot run autonomously.

A large crane has been added to both ships to recover fairing halves from the water.

Both ships are an impressive 260ft long.

FWIW I’m fine with this being a separate thread. They are very different ships from the dedicated fairing catchers.

Edit to add:

I mean new to SpaceX. They are both older ships that have been laid up for a while so were probably very cheap.

With Phobos and Demios, and according to the plan for p2p MANY other offshore launch and landing locations, SX is going to need tugs, support ships, and many others. In multiple eventually...
So the marine side of SX will be significant.
Edit:
the offshore towing is a constant need, but this comes with a comfortable base for SX crew for any safeing and management of the drone ships. Hiring tugs is expensive, and has less opportunity for SX to use for such additional purposes.

They may still need additional normal tugs for port entry and docking but this is a different matter.

2. Upon reaching the booster landing area, she casts off the ASDS and continues to the fairing splashdown area. She recovers the fairings and returns to the ASDS, which by now has the F9 first stage in it's Octograbber and has done everything that can be done remotely. I believe this would take less than a day.


Can't.  The ship has to stay near the ASDS for control and monitoring.

Can.    It’s possible to control and monitor the ASDS from anywhere on the planet.

Jim is correct, but "control and monitoring" doesn't have all that much to do with it:  The ASDS could, technically and legally, be left to it's own devices so long as the required "Not Under Command" day shapes (lights at night) are displayed, however response time in the event of an issue during the landing and Octograbber grabbing phases (and ain't we seen a few of those already!!) plus safeing of the landed booster and ASDS health checks post-landing ("Are we sinking?" Nope. All good then!") are all critical to SpaceX so, with millions of dollars at stake, they really do not want to be too far away.

The question is, what is too far away? Now that they are not trying to catch the fairings, could they alter the glide path to get them closer the ASDS?

Hummm I thought this was impossible?

Stoked to see this!
-First, the fact that SpaceX is able to repurpose oil/gas assets for space operations saves mucho $$$.
-Second, length of vessels will enable higher surface speeds for quick trips to and from fairing recovery zones.
-Third, multipurpose vessel: both ASDS towing and fairing recovery.

Ack! Got a little excited, see edit below.
-Fourth, the crane! Those cranes are capable of loading/unloading in a seaway because they can adjust for swell variability. That means easier fairing recovery, materials transferred back and forth to the ASDS at sea (if needed), and maybe even dragon capsule recovery.

This vessel purchase definitely needs it's own thread!
-----------------------------------------------
Edit: Turns out that the same company that built/refurbished the drawworks, NOS, makes off shore cranes of this type. The few pictures available seem to show the "Doug" crane as being one of the NOS offshore knuckle boom cranes (OC-K), but that it lacks the "Sealift Compensation System". The Shelia Bordelon had the swell compensating system on its crane, and testing by SpaceX must have shown that cost versus utility wasn't there so they opted for the straight knuckle boom system. Some links below for folks to explore:

Look at OCK section (pg 7) for some pics and stats.
Image is screenshot from brochure. Unfortunately, the SpaceX crane on Doug is painted white and blends into the background sky, so comparing pictures is difficult.

Thanks AstroDave for the infos!

As I don't have any knowledge about cranes, I searched some explanation about Sealift Compensation System. This video explains it well.

A new photo of Bob and Doug at the shipyard!

From this elevated view, you can see Bob (on the left) is much further behind in the construction process. The ship is missing a crane and the new elevated deck hasn't been painted white yet.

You can compare the IMO Numbers and see that they’re the same. Bob was Ella G and Doug was Ingrid. We are unsure about the prior owner, whether it was Edison Chouest Offshore or Island Ventures II LLC, but will update the article if we can verify.

  Strategically, the purchase and operation of these two ships speaks to a future involving not just fairings and ASDS platforms, but also servicing oil rig launch platforms with logistical support when they come online. Overall, just a great forward looking implementation of maritime operations.

Wouldn't it make more sense to use a crane on the edge of the platform for that?

That is one of the reasons the platforms and other off shore installations have cranes on them. Hope image helps.

My point was that these vessels do not have any specific features to delineate them as performing a platform support role. Indeed, previous vessels (MS. Tree and Ms. Chief) that were vessels originally built for that role - literally 'Platform Supply Vessels' - and have not been retained.

They look multi-role to me.

Why keep the crane-less ship if this one can do platform supply and fairing recovery and barge towing and barge control/comm?

Not sure if i understand exactly what you're both saying... but perhaps this can help..

PSVs or OSVs rarely have cranes on them. they're just big flatbed "truck" type vessels that haul deck cargo and some bulk tank cargo (dry cement, water, brine, fuel) to the platforms offshore. The biggest difference between Bob and Doug vs Ms Chief and Ms Tree is the station-keeping ability and redundant control systems. the Ms vessels were DP Class one with limited redundancy and failure mode capability requiring an abandon of mission if something failed. the newer vessels are DP class 2.

There is a "DP 3" too, with still more 'position holding capability'

Do we know anything about Doug and Bob's past?

The reason I ask I was looking on Google Maps for something and decided to have a look at SpaceX's South Seaside road facility and I saw 2 ships in dark grey and white looking very much like Bob and Doug.

Those ships are visually too small, almost by a factor of 2.  You can see the history of the ships by searching for their IMO number, which doesn't change across sales and renamings of a ship.  Both ships originally had the orange hulls of Edison Chouest Offshore.

Not much to tell.. they were essentially sister ships built in 2009 and named "INGRID" and "ELLA G" respectively.  Here's what's available in the ABS records:

INGRID (Offshore Supply Vessel)
Class State: Classed  Class #: 09195307
ABS Class Notations: ✠ A1, Ⓔ, ✠ AMS, ✠ DPS-2
IMO #: 9529889  Call Sign: WDF2598
Flag: United States of America
Lifecycle State: Laid Up
Port: Galliano, LA
Launch Date: 03-Nov-2009
Delivery Date: 15-Dec-2009
Functions: Offshore Supply Vessel
Gross Tonnage: 2998
Net Tonnage: 889
Design Speed Ahead: 14kts
Design Speed Astern: 8kts
Length Overall (LOA): 84.7344m
Breadth Molded (B): 18.293m
Depth Molded (D): 7.318m
Length Between Perpendiculars (LBP): 79.705m
Design Draft: 5.8644m
Comments:  Vessel has physical features for underwater inspection in lieu of drydocking survey (UWILD).
Builder: NORTH AMERICAN SHIPBUILDING INC.
Project Description:  280' General Cargo Carrier - PSV

ELLA G. (Offshore Supply Vessel)
Class State: Classed  Class #: 09195228
ABS Class Notations: ✠ A1, Fire Fighting Vessel Class 1, Ⓔ, ✠ AMS, ✠ DPS-2
IMO #: 9529695 Call Sign: WDE9523
Flag: United States of America
Lifecycle State: Laid Up
Port: Galliano, LA
Launch Date: 23-Jun-2009
Delivery Date: 03-Aug-2009
Functions: Fire Fighting Vessel Class 1
Gross Tonnage: 2998
Net Tonnage: 1071
Design Speed Ahead: 14kts
Design Speed Astern: 8kts
Length Overall (LOA): 85.366m
Breadth Molded (B): 18.293m
Depth Molded (D): 7.318m
Length Between Perpendiculars (LBP): 81.708m
Design Draft: 6.25m
Comments: Vessel has physical features for underwater inspection in lieu of drydocking survey (UWILD).
Builder: NORTH AMERICAN SHIPBUILDING INC.
Project Description: 280' General Cargo Carrier - PSV


So, the only thing significantly different between the two is that the "ELLA G" was kitted out for Fire Fighting.

I believe that is the length at the water line while loaded. I get a kick out of the LOA being listed at 84.7344 meters, or exactly 278 feet. One might otherwise think they measure boats with micrometers.

Please explain "length between perpendiculars".

I believe that is the length at the water line while loaded. I get a kick out of the LOA being listed at 84.7344 meters, or exactly 278 feet. One might otherwise think they measure boats with micrometers.

Boats and ships are generally designed with lines drawn out in sections lengthwise. "Length Between Perpendiculars" (LBP) is the distance between the first and last of the sections marked on the lines plan (a drawing that shows the shape of the hull). It is only one of the various lengths you might see. Examples:

LBP - 17' (this is between the line usually labelled "B" or 0 on the plans, runs through various Sections to the last one labelled "T" (for transom).
LOH - Length Of Hull. 17' 3" (for say, rubrails around the bow and stern). Sometimes includes the rudder, if outboard.
LOA or Sparred Length - This would include the bowsprit.

I believe that in commercial vessels, LBP is used as an official length, because it s least likely to change over time, unless the vessel's hull is actually lengthened or shortened.

Beam (width) can have different meanings as well. If you are a SpaceX Net-Equipped Fairing Catcher, your Extreme Beam will be a lot different than the Beam on your papers!

This all GENERALLY.

DWL (sometimes LWL) - is Design (or Load) Waterline. This is where the Architect determines an average loaded vessel will float at. There multiple waterlines on the lines plan, and used with the Section lines (and sometimes others), will give you the shape of the hull in numbers. A Marmac 300 Barge (OCISLY, etc.) will have different waterline lengths depending on load and ballast (because the sends are sloped).

Hope this helps!

If you'll allow laser tape measures in that definition, then actually yes they do - because it's the hull measurements that various fees and charges are based upon.

I get a kick out of the fact that the vessel was designed to be 280' long but ended up being a couple of feet shorter.. That always seems to happen with steel vessels and it doesn't seem to bother anyone much.

I wonder if Bob and Doug, the humans, were told about the naming of the boats beforehand. 
Im sure it would be an incredible honour for them, but I could see legal wanting to get an actual OK from them first. 
Just a random tangential thought of mine, I have alot of them.

I wonder if Bob and Doug, the humans, were told about the naming of the boats beforehand. 
Im sure it would be an incredible honour for them, but I could see legal wanting to get an actual OK from them first. 
Just a random tangential thought of mine, I have alot of them.

Shouldn't be hard to get permission from Rick Moranis and Dave Thomas.

But it would be classy if SpaceX invited Behnken & Hurley to the rechristening ceremonies.

Doug is en route to Port Canaveral, but Bob is riding out a Category 4 Hurricane in Port Fourchon.

Speaking of Bob... Doug made it around the edge of the worst of Hurricane Ida and is now back up to speed.

The vessel will arrive at Port Canaveral on Monday evening/night.

Shocking footage in Port Fourchon where Hurricane Ida made landfall earlier.

SpaceX's ship Bob is the smaller white ship directly in front of the larger orange one.

Wow!!  It's kinda hard to see where the land ends and the sea starts!  At least the ship looks okay though.
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.

Named after Doug Hurley, one of the first two humans to fly aboard a SpaceX spacecraft, there will also be a sister ship named…you guessed it…Bob, after Bob Behnken.

Back in April, I speculated on the idea that a single larger vessel could both tow the ASDS, move downrange to pick up the fairings while Octograbber secured the booster and it was safed, and then tow the ASDS back, thus saving on the number of ships.

After over 15 years of wrong predictions (can you say "water tower", anyone?), I may finally have gotten one right.

There's hope yet!

Here's drone footage of the aftermath.  Bob is visible at 2:09 and again in the background at 3:21.  Clearly any work remaining on Bob will need to happen elsewhere.

Bob appears to be a missing a satellite dome (see Doug for comparison). Possibly damage from Ida.

Overall, in impressively good looking condition given what it just went through! Of course, looks could be deceiving.

Yep, looks can be VERY deceiving!  If you've never been on a ship tied to a dock in a hurricane (cyclone, whatever..), believe me, it's a mind-blowing experience you never want to go through again!  Even if the ship hasn't sunk (a bonus) there is still potential damage to comms antennas, lifelines, mooring lines, winches, lifeboats/tenders, clogged cooling water intakes and all that kind of fun stuff to deal with later.
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.

If the boat is all messed up from the hurricane, would they have already put out to sea with it? Twice?

Define "all messed up".  If they needed to repair something you'd wouldn't see in a photo (eg. some part of the navigation, drive or mooring system) and wanted to make sure all was okay - or even if nothing much was wrong at all; they just wanted to get away from the mess for a bit - then, yes, they would.

Offshore rig supply vessels have to be rugged to continue to operate, and stay on station, despite severe adverse weather. These are not coasters, etc, they are tough working boats. I bet they are pretty "hardened" against tough conditions, and damage will be superficial. Maybe the radar dome was a redundant second, and winches designed for pulling oilrigs, will be tough and properly mounted. etc...I do accept there may well be some hidden issues or damage... but I bet its not critical.

They're rugged enough to survive inclement weather out at sea, but that's different from being repeatedly dashed against a dock.

They look like a goose.

I'm sure the financial team at SpaceX looks forward to the day they don't have the cost and maintenance of running a small navy.  It's absolutely worth it, but they can get even faster and cheaper once they don't need it.

Why do you think they're averse to that?

Why would the finance people even have an opinion on how to retreive boosters?  They can have an opinion on how to book-keep the fuel costs, but that's about the extent of it...

Also how are those costs different from maintenance of ground infrastructure assets, or ground vehicles, or salaries of overhead people like themselves?

Seriously I don't get the aversion.  And obviously neither does SpaceX, since they're building sea-based launch and recovery vessels..  I think they kind of like having a navy...

Are they named after the famous Canadian Hosers Bob and Doug McKenzie, hosts of the "Great White North" sketch on SCTV?

One of these new SpaceX fast boats has had its tracker turned on and these boats do have names!

Introducing... Maverick and Goose!

You do realize that the head of finance at SpaceX wears many hats. He is also the chief engineer, production manager, publicist and of course the CEO. ;)

With the introduction of the Starship. The SpaceX Armada will have to be bigger and more capable. There are more contingency situations at more far away places.

One of the new task for the expanded Armada is communications relay boats deployed for global Starlink downlink coverage. SpaceX need to eliminated zones where they don't have ground station coverage to receive signals from orbiting non-Starlink spacecrafts.

I assume you are being funny, here. The biggest and most immediate reason to implement ISL (inter-datellite links) is to remove the need for universal ground station coverage, especially in ocean areas. but more generally in all low-density areas.

The cost of their fleet is rough. Yet a lot less rough than expending boosters like every other launch company.

You are thinking of user terminals on the ground. However think you need ground stations to pick up signals from non-Starlink SpaceX spacecrafts in orbit. Have edit my previous post to clarified.

Spacecraft in orbit can communicate with satellites in orbit. I don't know if SpaceX will integrate spacecraft comms with Starlink or if they will use a separate constellation. By comparison with Starlink, spacecraft comms has relatively low aggregate bandwidth demand, so it's feasible to use RF instead of lasers, especially since some RF bands are not useful space-to-ground and are therefore relatively uncluttered for space-to-space.

Bob arrived back from a maintenance trip to New York City this morning.

Should depart again tomorrow, towing ASOG, for the upcoming Starlink 4-2 mission.

Ever wondered how SpaceX launches and retrieves the fast boats (Maverick and Goose) from support ships Bob and Doug?

Here's how, thanks to the nsf.live/spacecoast live stream 😉

It's a rare sight to see all of SpaceX's East Coast recovery fleet together these days with such a busy launch schedule

Here's a photo from this morning from http://nsf.live to capture the scene at Port Canaveral🌞

SpaceX support Bob has set destination as Savannah and appears to be about to get underway.

Not sure what is going on with Bob, the vessel hasn't been used for recent missions and has had a  boom wrapped around it in Port Canaveral. (Yellow thing in below pic)

Twin ship Doug has been pulling double duty and SpaceX bought in a second contract tug to keep schedule.

Signet Titan zipped up the coast after dropping off JRTI after SL 6-12, and is now visiting Bob in Jacksonville.  What's going on??
