To what extent will a Crucible crew be able to repair damages sustained to their own hull and components?

The Crucible can repair anything… except itself. Really makes you think. No, there's a good amount of capacity for self-repair. Internal components are fully accessible for repair, and most minor damage should be handled by the ship itself through use of EVA, onboard tools and drones. Major hull repair might require a dry dock visit or another Crucible, as the repair arms don't reach the entire ship.
