Narrative:
I (seated in the left seat operating as the relief pilot) noticed the left engine oil pressure light flickering. The PIC was on his crew rest break in cabin while these events were transpiring. I informed the first officer who was the flying pilot and reached for the captain's QRH. Subsequently the left engine oil pressure went below the red limit. Recognizing the seriousness of the moment; we elected to run the appropriate checklists which involved an engine shutdown prior to getting the captain back to the flight deck. We had declared the emergency event immediately and were descending to FL240 and had received the diversion airport weather all prior to the captain's return. I experienced a slight delay in getting a flight attendant to summon the captain but this proved to inconsequential. The captain resumed command upon his return and affected a good landing in good weather. All three flight deck members did a post flight visual inspection of the left engine and saw fluid from the lower part of the engine on the tarmac.
