Shipyard workers

If it's a shirtsleeve environment, you want the fabric on the inside,so it's held in place by the framework.

in my take on the OTU, most slips are established bays, up to 100KTd, but the dreadnoughts are built in sections in bays, and then vacuum assembled in frameworks.

Hi,

That probably makes alot of sense. In alot of modern shipyards alot of work is done inside assembly sheds to make fairly large mostly complete sections, and then these sections are often typically moved to the assembly way to be put together. As I understand it, alot of this has to do with the fact that assembling stuff in a controlled area/space can be done simpler and less costly indoors (in a controlled environment) than outdoors, or on the waterfront, in part because you don't necessarily have weather impacts but also in part because its easier to have all the services, etc that you need in the building shed than at various locations on the waterfront.

For starship building, especially if in orbit, I wouldn't be surprised if there wouldn't be some similar tradeoffs. Specifically, by buicling some blocks in "buidling bays" you could have all your required services etc right there and people could be working or reviewing and monitoring the work of robots etc in more more natural environment rather than if working in a vacc suit in space. (And to be honest one thing that still eludes me about vacc suits is how would you wipe the sweat from your brow etc if its in an enclosed helmet :) )
 
Not just ship building but construction in general. Buildings of all kinds are done that way, i.e. infrastructure and shell completed and closed in and then completed on the inside.

We do it that way for weather though.
 
Youbetcha! Back when I was running Cat5 and installing networks for a living, I wasn't going to start a project without a weather seal on a building... ;)

Yes, and I was the supervising/managing engineer/project manager, getting the envelope closed is before the rough ins. :)

Heh, very similar experience. I was self employed so I pretty much did everything from sales, network design and the build out. A lot more headaches and hours than what I'm doing now... :)

I often admired the freedom alot of the sub's had, esp guys like you with network stuff. Last job I was PM and a company officer running multiple projects, things such as an elevator going down a hillside that had a 30% grade with a stream running down the property line, had a mudslide the friday before a monday pour of 200 yards of concrete. And don't tell me the intern mirrored the plans so all the steelwork I designed was backwards? Good thing all the cabs are custom built for the shaft, and I would still have nightmares of it tearing free during a major quake and my wife would find me at 3am in my office going over the connection numbers.

Bottom fell out on that market though, so I took the time to go back and get a business degree, I am officially sick of being a fulltime student again. The head of the business department called me into his office and said I should think about an MBA because I'm 94th percentile in the field on academic performance nationwide. My automatic reaction is no way I don't want to be 47 and graduating, I already have two other degrees and a certificate in financial management, but if I turn down a scholarship, I might not get it again...

Give me a trusty far trader and have gauss rifle will travel any day.
 
...as I'm here slacking. ;)

But thinking about a Spacecraft Manufacturing Facility is way more interesting than a paper I'm writing on the FDI in Bangladesh.

Luckily the current Remote Support job I have is fairly brain dead enough so that I can multitask gaming and still do a great job.

But yea, this is a very interesting thread... :)
 
For orbital construction, instead of scaffolding moving pieces, I'd think you'd have major sections/parts put together using something like tugs or other thruster type movers. Push/Pull the major hull plates together, weld/join them, push/pull the major sections together. When you get a section closed, pump in atmo, turn on basic Life Support and start building internal sections/decks. Scaffolding would be a boundary marker and a base for smaller parts/workers to be moved around the outside.
 
Doesn't matter how sturdy. It is the MASS difference I was aiming at.

Provided that it's about bringing part A into connection with part B, mass is almost irrelevant in 0G - Everyone can move multi-kiloton parts. Doing so quickly, well, that's another matter. It makes little difference if you move A to B or B to A.

Now, mass vs structural strength and force is a consideration for how quickly one can assemble A and B into AB, but that's an entirely different issue, especially since in 0G, you can still have guys working on fitting out both...
 
Because I've seen scaffolding put around ships while being built. In order to have enough mass, it wouldn't be scaffolding. ;)

I guess you overlooked what I previously wrote:

"I'm talking about a similar concept but for use in orbit. Sturdy enough to provide support for construction, but modular."​

What else would you call a temporary structure used to support people and material in the construction or repair of large objects in orbit? It seems to me that 'scaffolding' is a perfectly appropriate term for it, but if you have a better one, do let me know and I'll switch to using that.

The main point is that there does not seem any reason why a permanent structure of fixed size should be necessary.

Also, once you get the outer hull even partially closed in, pressurize it and work from the inside. I would think getting the primary superstructure and outer hull completed would be the first step anyway.

This doesn't allow for work to contine on the outer hull without continued having to 'suit up.' I see working in a vac suit as a big negative. It also doesn't allow for situtations were something outside the hull having to temporarily penetrate it to be used inside. Again building temporary air locks of a sort would be an inconvience.
I think the scaffolding with some tent material is a very workable solution. You get a pressurized area you can work in shirt sleeves and it can be used without the tent when you require a vacuum to do things.

In the RW, the bulk of labor for large scale construction projects consists of migrant and transient workers. The number of workers at any given time will vary - often quite drastically based on scope and current stages of constructions...

Most shipyard labor will be trained specialists in various fields. While there will be a need for some degree of unskilled labor they will not be the ones the yard retains as full time employees.
There will also be a need for a large number of highly skilled shop workers who fabricate parts and equipment for the ship being built. They would not necessarily be the ones installing stuff but rather just making the parts and sending them out the door to the construction site.
For example, the drivess are not going to be fabricated on the ship but in an drive shop or shops. They would then send the finished components out to the ship for installation.
There would be dozens of this sort of shop in the yards and in addition numerous subcontractors on and off site making components that in many cases feed to the shops that in turn feed parts to the ship.

A combination of Work Pods(10 ton ship that is basically a thruster, small fuel tank, cargo area to haul parts, a large "Waldo" arm) and various sizes of portable "Work Tents" that get setup on the hull.

MgT has a Maintenance Pod design in the MgT High Guard Book 2.

The original question doesn't have a single valid answer - especially with TL and government types considered.

However, the size of the shipyard could determine the size of permanent workforce - the management and skilled labor requisite for undertaking the scale of shipbuilding a shipyard is capable of producing. Dave's approach should suffice for the technical side of things... with the larger bulk of the direct and indirect labor labor force determined by other factors. (How many to build a section of hull is dependent on method of obtaining resources - asteroid vs strip mining - working the resources - smelting/casting/welding - and local work regulation and organizations such as unions, government work programs, migrant policies, etc.)

The construction capacity of a shipyard may be dependent on the size of the local and temporarily available (in-system or interstellar) workforce. The capability of a shipyard (ala drive TL manufacturing) would affect the requisite size of the shipyard.

Here is a thought, let's make a forumla that works for figuring how many employees a down port and highport shipyard needs, and assume TL 10
Then you divide that number (TL/10).

So, a shipyard at TL 10 that needs 120,000 employees would only need
150,000 employees for a TL 8
and 100,000 employees for a TL 12

But what figure (in general) should represent the difference between a down port and a high port ship yard?

No, slacking here just Chemo treatment for Cancer, but I totally agree, this subject is much better than what I am doing in RL. :)

I'd say it is more likely an inverse expotential curve for a given size of yard in capacity.

That is, as TL goes up the number of workers decreases expotentially. So, a TL 8 yard of given capacity might use say 50,000 workers while one of 9 uses 30,000 and a TL 10 is down to 15,000.
As a micro example, at TL 7 you have a man and helper operating a large metal part fabrication machine. At 8 it is down to one man. At 9 he is gone and the machine computerized with one worker "supervising" several machines. At 10 it is fully automated with just a supervisory few workers in an office and at 11 it is down to one or two people....etc.
