Just so long as the remaining part of the ship remains watertight and can maintain a positive bouyancy, bad luck for Herr Kaleun.
I have read WWII reports of tankers taking seven torpedoes and still only being classed as a write-off, not an actual sinking. If your AI units are set at expert, good luck sinking them, this is random in the game but the higher difficulty level you play at, the more common it is to find expert AI units.
