Bismark is a battleship that values discipline a lot. Before she arrived, the naval base was full of undisciplined ship girls. Literally "freely (acting)", but I thought this should make more sense. Correct me if I'm wrong.

For the sake of the naval base's order, she would fight discipline violators and boldness!

Kora!! No lovers' rendezvous!

Hey, stop it. "kora" and "oi" are both understood as "hey" in English but "kora" is used when you have meaning to scold someone, "oi" is just used to get attention. For Nagatsuki is using these two in the same sentence, I made this tn.

Kora!! No playing in stand by!
