Narrative:
The flight was en route from ord to zrh. This was a widebody transport on an extended range overwater flight. Approximately over yul, the flight called and advised one of the engine driven generators had failed. At that time, I contacted maintenance and they suggested we land the aircraft short. I then referred to the aircraft operating manual and determined the flight could continue. I relayed this to the crew and the captain concurred. Just prior to the overwater portion, the flight again contacted me and advised the EICAS was displaying an intermittent status message on the APU oil quantity. I called maintenance and they advised there was a history of oil problems with the APU. They again suggested we land short. I contacted the flight and advised the crew of the history on the APU. At that point, I suggested landing at jfk. The captain felt comfortable to continue. We then discussed our options should the APU fail. Approximately 300 NM from that point, the APU failed. The captain declared an emergency and diverted to yyr. It is my opinion that the captain and I made sound decisions and operated the flight safely and legally.

Title: AN EXTENDED RANGE WDB CREW HAD A LOSS OF 1 GENERATOR, THEN THE APU. THEY LANDED WITHOUT FURTHER INCIDENT AT AN ENRTE FIELD.
Narrative: THE FLT WAS ENRTE FROM ORD TO ZRH. THIS WAS A WDB ON AN EXTENDED RANGE OVERWATER FLT. APPROX OVER YUL, THE FLT CALLED AND ADVISED ONE OF THE ENG DRIVEN GENERATORS HAD FAILED. AT THAT TIME, I CONTACTED MAINT AND THEY SUGGESTED WE LAND THE ACFT SHORT. I THEN REFERRED TO THE ACFT OPERATING MANUAL AND DETERMINED THE FLT COULD CONTINUE. I RELAYED THIS TO THE CREW AND THE CAPT CONCURRED. JUST PRIOR TO THE OVERWATER PORTION, THE FLT AGAIN CONTACTED ME AND ADVISED THE EICAS WAS DISPLAYING AN INTERMITTENT STATUS MESSAGE ON THE APU OIL QUANTITY. I CALLED MAINT AND THEY ADVISED THERE WAS A HISTORY OF OIL PROBLEMS WITH THE APU. THEY AGAIN SUGGESTED WE LAND SHORT. I CONTACTED THE FLT AND ADVISED THE CREW OF THE HISTORY ON THE APU. AT THAT POINT, I SUGGESTED LNDG AT JFK. THE CAPT FELT COMFORTABLE TO CONTINUE. WE THEN DISCUSSED OUR OPTIONS SHOULD THE APU FAIL. APPROX 300 NM FROM THAT POINT, THE APU FAILED. THE CAPT DECLARED AN EMER AND DIVERTED TO YYR. IT IS MY OPINION THAT THE CAPT AND I MADE SOUND DECISIONS AND OPERATED THE FLT SAFELY AND LEGALLY.
