Then she apologises - but without turning around or looking up, so it seems more like she's apologising to the Simoun...

Yup, Guppy's correct.

Spoiler for who Aeru apologized to:

Aeru says, "Gomen, sonnani yogoshichatte," which means, "Sorry to have dirtied you so much." In other words, she's apologizing to the Simoun vessel.
