Meaning of "Damiyat?"

I went to look up something on Wikipedia today, and as usual was distracted by the featured article.

Today’s article was about Jesse L. Brown, the first African-American naval aviator in the United States Navy. He had a ship named after him which, after a long and distinguished career, was leased and then sold to Egypt, who renamed it Damiyat.

Idle curiosity – I’m just wondering what that name means.

Damietta is an Egyptian port.

Ignorance fought! In record time. Thank you.
