Mobile Engineering City

[Garyius2003]

Where have I messed up? What have I missed?

I had an idea for a ship, really a special purpose creation with a large main city/factory ship.

The ship would be a 500,000 3I surplus TL13 rider carrier, with most of the weaponry stripped out, and lots of bays. The idea is that the ship jumps from place to place, and spends a few years there doing heavy orbital engineering projects. Along with the huge city ship are smaller ships for more specialized tasks. I went with dispersed structure.

With the concept that the ship kept three hundred turrets and the damper, but converted 3 of the J-4 fuel tanks to living and working space, this is that I got:

MISCELLANEOUS

I assume that the 52k tons are mostly factories, skilled trade shops, design labs, and schools/shops/parks.

Add in a fleet of tugs, work ships, fuel skimmers, and speciality ships, and you have a complete town and engineering shop read to build a high port or other orbital something on only a few decades contract.

My idea is that the ship was purchased or issued out of reserve fleet, most tankage was converted into living areas and work areas, and the former rider spaces were replaced with work/hanger bays.

I left the drive alone for the same reason I left the comp at 7fib. They use the 7 for keeping station/running the plant/life support, but they have other computers to do the design and builds.

It was quicker and cheaper to leave the J-drive with only an annual, and they only jump a few or more jumps every two or three years to get to the new worksite. I also think they get the use of an Imperial Navy Oiler if they have to deep space jump since they are limited to J-1 now. Easy enough to line up, since their schedule is likely booked up 100 years from now.

Most of the coversion work was pre-fab hangers, and the living spaces and workshops. In the case of the hangers it was plug and play, in the case of the former tankage it was remove the skin, insert prefabs, replace skin.
