On a more positive note, I've been revising my previous effort at deck plans and have come up with what looks like a promising engine room for any ship mounting standard Jump-F (35 tons), Maneuver-H (15 tons) and Power Plant-H (25 tons) drives all laid out in a single deck.
35 + 15 + 25 = 75 tons * 2 = 150 deck squares (roughly)
So I worked out an engine room that is 19 x 8 = 152 deck squares and simply filled up the rectangle.
I even went so far as to try and make the jump drive (centerline) as close to 35 tons/70 deck squares as I could, and even included the detail of the 6 tons of jump capacitors (LBB5.80) used in Jump-3 drives in the 400 ton form factor. The power plant and maneuver drives come as port/starboard pairs flanking the jump drive, and I have the power plant(s) forward with the maneuver (
HEPlaR) drive(s) exhaust system aft on a linear throughput line. There's even a high power EPS conduit between the two power plants for crash energizing the jump capacitors to jump.
I've been using snippets of parts from
Starship Geomorphs 2.0 to make the drives with (now that I've figured out a method to copy/paste reliably using my meager tools to creatively assemble them) and I'm rather pleased with the result. There's even 2 work stations crammed in the the engine room (and engineers had better not be claustrophobic!).
This engineering deck arrangement can then become a "reusable standard" for any other ships of a similar hull size and configuration.
Basic idea is to put all the drives and crew living/work spaces on the main deck, leaving the upper deck for embarked small craft and external docking points for towing external loads, and then doing essentially the same again as the cargo bay on the lower deck.
Enjoy.
After getting the engine room space finalized, I can start roughing out the rest of the ship and populating it with "stuff" to make a proper deck plan out of it. Still need to make some decisions about upper/lower deck access arrangements, how to rework the crew areas forward of the drive room and more, but it's coming along.
