Narrative:

At FL390 flight crew noticed a continuous fluctuation of oil pressure on the right engine between 70 to 85 psi. Oil quantity indicated 0. An amber EICAS message; 'right eng oil press'; annunciated on and off intermittently. Also; the 'right eng oil press' light on the forward panel began to flicker on and off. Flight crew referenced irregular procedure; eng oil press - left(right); and contacted dispatch via phone patch. Concurrently flight crew contacted approach to establish radar contact and advise of situation. The purser was briefed on situation and advised the right engine may be shut down as a precaution. Contact was established with dispatch with conference call to maintenance. Maintenance advised crew to follow flight manual irregular procedure. The current engine parameters of oil pressure now fluctuating into 'red' required engine shut down. Dispatch and flight crew consulted as to safest and best single engine destination at this point. After consideration was given to the variables it was concluded and mutually agreed to between both dispatch and the flight crew that the safest and best course of action was to continue to current destination. Dispatch informed us that emergency equipment would be standing by. Dispatch advised us that appropriate facilities would be advised of aircraft emergency status and of dangerous goods; dry ice; on board. Dispatch then signed off HF frequency. The captain established himself as flying pilot for approach and landing. Radar contact was established with approach with clearance direct. Flight crew ran and completed irregular procedure; eng oil press - left(right). Flight crew ran and completed irregular procedure; engine failure / shutdown in flight. Flight crew referenced landing performance 'landing distance abnormal or irregular configuration. ATC cleared flight to a requested lower altitude. The flight crew established a single engine descent. The purser was advised that the right engine was shut down as a precaution; a cabin advisory was in order; time remaining; to take their seats early; a normal approach and landing was expected; and that the pilots would make a PA announcement. A single engine approach was briefed by the captain. The approach descent checklist was completed. The 'fuel config' light illuminated indicating fuel imbalance. Irregular procedure was completed to establish fuel cross feed. ATC cleared flight to cross the VOR at or above 8000 feet cleared ILS approach. An uneventful single engine approach and landing was conducted. After landing emergency equipment was advised not needed. A single engine taxi was then made to a normal parking spot.

Title: B757 flight crew experienced fluctuating oil pressure and low oil quantity at FL390 approaching destination during an oceanic flight. Engine is shut down and flight continued to destination after considering a slightly closer diversion airport.
