Wikipedia puts the volume at 421 million cubic kilometres
https://en.wikipedia.org/wiki/Ceres_(dwarf_planet)
421 million cubic kilometres is 4.21 x 10 to the power of 17 cubic metres.
I think a DTon is 14 cubic metres
so that's something like 30,071,428,571,428,571 DTons or something.
It would be a big ship........

First order of business, bung all the holes.

Lousy ship, fantastic massive base of operations as the surface is a 100 km mantle of ice (200 million cubic km fresh water). It could just be a facility for fresh water mining but can have the capacity to support a central point for asteroid belt mining as a huge source of fuel for ships. With a surface gravity of 0.028g and escape velocity of 0.51 km/sec, it would be excellent as a ship downport.
Oh, and there might be life in the liquid water under the mantle.

So, how did they manage to use that all up by the time The Expanse takes place?
Yeah. Well the game's going to start with the work only partially completed and they add to it over time. I'm going to have lots of pre-statted modules so the only need to add the new number in instead of recalculating all of it. The whole thing has a modular hull, which in game terms I'm representing with breakaway hulls This lets them lower the power plant and fuel storage as they drill, and rearrange the interior as needed.

I have an old adventure (1982) by FASA called Fate of the Sky Raiders featuring a starship that is 10km x 8 km x 7.5 km (50 billion dtons) in size built by a minor human race as they fled the Gushemege sector from the Vilani by crossing the Great Rift by sublight then using jump to the Far Frontier region. It was a generation ship to carry millions of people. Many normal systems are modularized and dispersed throughout the ship. The game has the deck plans as large modules connected by access shafts for exploration and encounters. One way to represent the interior of a huge planetoid vessel.

That would be bigger than the Death Star in Star Wars, though not the one in the latest Star Wars film!Morningkiller said:

Stripped it off and sent it to Mars.
That I can see. What I can't see is if they can do that, why don't they have a similar technique for mining Saturn's rings? Instead of guys using grabber claws for chunks of ice, they should have factory ships just scooping those beautiful rings up for corporate profit.
IN reality running out of water, or any material once you have spaceflight advanced enough to reach Ceres is highly improbably. Between asteroids moons, and comets there's enough loose material floating around the system to build a few planets, and then some.
One or two good sized nickle iron rich asteroids wold be enough to build entire cites out of. Mars has enough light metals to do us for a very long time..unless we just fire millions of tons of material into the sun for giggles and grins

What's the gravity like at Ceres?

For the people that keep getting thrown down the airlock in Ceres, shouldn't they have floated down?
