at moment when ships are larger more slower movements inside the ship - i suggest a elevator for muilt deck - example coal to engine would delivered by elevator if they are on direct path if ship has 10 decks tall then elevator would be useful or stairs (ladders can used for 2 decks)
also fire proofing rooms would benift this example fire sprinkers installed throughout reduces chances of fires but only works if fire tank is connected with it but if fire tank is damaged fires can start spreading
