Sir Walter msg #493:
Thank you Nathaniel, that is a good option, as long as you do not mind the jump drives being stripped out to make room for the refinery/manufacturing plant. I had been debating on what to do with TAMI and Veronika as they would be too easy to run as GMPC's. Sticking them there would take care of that problem.
While Nate doesn't particularly like the idea of limiting future options, he is also not focussed on a ship as a ship. More as a tool, and the resources it makes available.
Nathaniel's backstory reason for joining the Longshot was 2 parts. One was to hitch a ride to Concorde, to get to his own ship. The other was to get some ship experience, to learn how he liked the lifestyle. His previous ship experience was as a passenger, going to his next work assignment. With that as a background, by the time the relevant questions come up, he decides that the volatile Longshot environment is more interesting than trying to run the lab ship as a business of his own. Using it as a resource to buy into the Longshot Enterprises business instead looks more stable, and with fewer headaches. Sir Walter can deal with that instead.
If TAMI's choice is to stay with Longshot as well, that would be part of the 'interesting'.
Speaking about being geeky enough to 'appreciate' tech …
Have you planned the details of what kind of refining and manufacturing Sir Walter would be focusing on? Would that be mainly to supply the needs of Cassandra, or for export? What TL would the output be? I assume that you are aiming at micro-brewery scale, since a 400 ton laboratory ship does not seem suited for mass manufacturing. Especially if you are planning to refine (and smelt?) the raw materials needed for the manufacturing.
The Traveller information (I have) for manufacturing and refining is on page 60 to 62 of Mongoose Traveller 2e High Guard.
GM is of course free to adjust the details, but as a base
https://wiki.travellerrpg.com/Cassandra_(world) shows the UWP as B000538-C for year 1116. The current in game Imperial Startdata is 317-1114 (plus about a week), which lines right up with that. That puts the population in the 100's of thousands, plus varying transitory residents. The base system TL is C(12). Are you aiming at a higher TL refining and manufacturing, acquired from Concorde? HG shows an increase in efficiency (higher output, lower power, crew, costs) at TL13.
The wiki shows the belt as a solid source of mineral resources, HG shows 25% production rate increase if a manufacturing plant is in a system that can provide the right raw materials. The only case that matches here is Asteroid trade code, Pharmaceutical goods, and Specialist plant.
Hmmm, something that player knows about, but Nathaniel not yet, is the drug samples being researched. Something to slide some small personal batches through? Or would that be Medical Supplies or Biochemicals instead of pharmaceuticals?
A detail that I do not see in the HG manufacturing information, is how much raw material is needed to create a ton of finished goods. Assuming that is 2 to 1, the same as smelting raw ore to raw materials, then working backward from a goal of 1 ton of goods manufactured per day, 2 tons of raw materials are needed, which will need 4 tons of ore. I assume that not all of the ore is suitable to use in the target process, so make that at least 10 tons of ore (likely more), with the rest being sold as is (or smelted and sold).
Scaling the numbers from HG:
A TL 13 specialist manufacturing plant producing 1 ton of pharmaceutical goods per day, in a system with the asteroid trade code, would be 14 tons (rounded up from 13.3), need 1 power (0.56), 2 crew (1.17), and cost 14 MCr.
A smelter producing 2 tons of raw materials per day would be 20 tons, need 20 power, and cost 10 MCr. No crew requirements are shown.
A TL 13 Mineral Refinery producing 10 tons of ore per day would be 5 tons, need 5 power, a crew of 1 (0.2), and cost 20 MCr.
That is 39 tons, 26 power, probably 3 crew, 44MCr
A 400 ton Laboratory ship has 25 ton used for jump engines and 80 tons for their fuel tanks. The above could be tripled, and still keep almost all of the laboratory space.
Tripling, and adjusting the rounding
Specialist Plant: 3 tons per day, 40 tons displacement, 2 power (1.68), 4 crew (3.33), 40 MCr
Smelter: 6 tons per day, 60 tons displacement, 60 power, 30 MCr
Mineral Refinery: 30 tons per day, 15 tons displacement, 15 power, 1 crew (0.6), 60 MCr
115 tons, 77 power, 130 MCr
It is not clear if that accounts for the hangers and facilities for tugs to bring asteroids to the ship to process. Some of that could be handled by the ship being able to move to the asteroid. I assume though that the choice of Laboratory ship as the base, was to be able to do manufacturing that is sensitive to generated gravity fields. Maneuvering the ship while processing was in progress would negate that. Even too much tug activity could cause interference. Careful scheduling, or limiting close work to reaction drives might be required.
There is enough material being moved between refinery, smelter, and plant to need some temporary storage. That could use up more of the ship internal space, but I think external 'cargo nets' would do the job just fine. Along with some drones to move it around as needed.
My own choice for the scenario, would be to keep the gravity sensitive manufacturing off of the ship itself, in a 'true' zero G (micro gravity) environment (a module). Possibly tethered to supply power and access via non gravity drive 'cable car'. Where possible, all control functions would be done by remote access, with only occasional physical visits. Drones and remote operations for most of that. Use the recovered space for drones, remote operations, inventory. As a 'convenience', the above manufacturing plant is 40 tons, the same as the Pinnace. Potentially it could 'dock' in the same location, when it is not on the tether, and still get the advantages of a zero g environment.
I could expand that more, but expect that is plenty for anyone here. I am used to working with the letter the rules, and seeing where I can take it. From what i have seen, most here are more used to using the rules a guide, and not worrying about details.
