Old School said:No doubt the low berths are the most efficient way to move people cost wise in a large scale evacuation. I imagine a scenario in which the logistics are worked out to get the ships in and out as quickly as possible, essentially an assembly line boarding and disembarking, with an army of doctors at the destination to bring people out of the low berths. This obviously doesnt apply in a one off, just shipping a bunch of troops for this one mission scenario.
The same size ship could transfer about half as many people steerage class, which may be preferable for children and the infirm, depending on how you apply the medic check when removing someone from a low berth. Much lower power plant requirement, but more room for galleys, stewards, on board medics, etc when the passengers arent frozen.
When you're shipping cryo trays, you might as well use the same approach as bulk cargo (because that's what you've reduced your passengers to) - use modular freighters like the one from High Guard - a 200 dTon 'container' can hold:
Class A fission plant (because you're not trying to run drives and don't want to bother refuelling) - 4 dTons
Fissile fuel (good for a year of operations) - 2 dTons
Compact 'Bridge' (just so it's a 'legal' standalone design) - 7.5 dTons
Some 'spare space' for the odd vital possession (medicine, personal ID, etc) and Autodocs to supervise reanimation - 6.5 dTons
Leaves 180 dTons in the 'standard' 200 dTon containers we see in those freighter designs.
That's enough for 360 'standard' low berths. An 'emergency low berth' can't be used for low berth passengers but we're talking about emergency evacuations, so step right up. It holds 4 people per dTon, so each one of those containers can hold 720 people.
The thing is, you can have those containers dispersed across a world, and then ship them up to orbit to any old 'container ship', which turns all the megacorp vessels in the region into emergency people haulers.
