So in my opinion there should be like for example air units, which take only energy to operate. Those air units make sure, that the human crew can breath inside the ship. And there should also be a kind of robotic crew, which obviously needs more energy and can maybe be a copy of the normal crew, but as robots but it could also be a system of robotic arms and conveyor belts which need to be placed by the user one by one. The user/player needs to build a kind of automated factory inside the ship (advantage: faster and they don’t need air).

The entire crew already has access to space suits, why wouldn't they simply resort to wearing them inside if oxygen supply was such an issue?
