The turbulence procedure on the A300-600 was to transfer any remaining fuel from the trim tanks to the main tanks. As we know,the A300 was a conventional aircraft. As for the A330,we dont have any procedure such as this because in Normal and even in Alternate laws,the FCPC and FCSC logic (as best it can)take care of any turbulence (flight path excursions) making the FBW aircraft a stable platform.
I can only imagine what the aircraft behaviour will be like with system degradation,full trim tanks and moderate to severe chops at altitude.
