Or, at least, still useful as a hulk. Or two.

HMS Porcupine is an interesting case. A ship so heavily damaged that even the Royal Navy, which put Javelin back in service after losing her bow and stern, considered her broken. Not worth the effort to repair.

Yet, in spite of that, the ship remained afloat.

So, instead of simply scrapping her, the British got some use out of the almost-new destroyer's hulk. Giving rise to HMS Pork and HMS Pine, probably the most interesting use of a wrecked destroyer that I can think of.
