ADVISED FLT OF POTENTIAL CTR OF GRAVITY SHIFT SITUATION VIA ACARS IN THE EVENT OF RAPID DSCNT AND PROCEEDED TO GET MORE SPECIFIC NUMBERS. AS IT TURNS OUT 5 CARGO CONTAINS WITH TOTAL WT OF 2842 LBS WERE AT RISK OF SHIFTING. HAD SUPVR RUN IN TRAINING MODE SCENARIO IF ALL 5 CONTAINERS MOVED TO THE MOST FORWARD POS POSSIBLE. NUMBERS GIVEN BY LOAD PLANNING WERE MAC 34.3 VICE 33.9 ANU 3.6 VICE 3.5. IT WAS AGREED (WITH CREW) THAT ACFT WOULD NOT BE OUT OF LIMITS. PASSED INFO TO CREW RELAYED BY ENGINEERING THAT IF THEY DIDN'T MOVE BUT CAME UNLATCHED THEY WOULD BE 1 INCH OFF. IF THEY DID MOVE IT MAY CAUSE DAMAGE TO WALLS AND MAKE NOISE AUDIBLE TO FORWARD GALLEY AND COCKPIT. PROVIDED CREW WITH RPTS AND CAT ALERT INFO OF POSSIBLE MODERATE TURB ON DSCNT E OF SFO. OFFERED STOP OPTION IF COCKPIT FELT UNCOMFORTABLE WITH THE SITUATION. LOAD SUPVR ADVISED ZZZ ADVISED VIA ZONE (ASKED RAMP SUPVR TO CALL ME SO I COULD GIVE HIM COURTESY CALL REGARDING THE SITUATION SO THEY COULD PREPARE DATA FOR INVESTIGATION).

CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THIS STATION NORMALLY HAS NO B777 DEPS AND THE LOADING OF THE CONTAINERS AND THE LATCHING OF THE CONTAINER STOPS WAS NEW AND MAY HAVE INVOLVED LACK OF TRAINING. THE CTR OF GRAVITY WAS ONLY AFFECTED SLIGHTLY AND NOT A SAFETY OF FLT PROB. THE RPTR HAS NO INFO IF ANY DAMAGE WAS INCURRED ON LNDG AT THE TERMINATING STATION.
