Narrative: We had reached our initial cruise altitude and I was on my rest break when I was summoned back to the cockpit. By the time the Captain had a moment to open the door for me; he and the other FO; who was flying; had already [advised ATC of the situation]; pulled the power back to idle on the number 1 engine; coordinated a descent and turn back to [departure airport] and spoken to dispatch. I was quickly briefed on the situation; and asked to get the QRH. I read the checklist for engine oil pressure; which directs you to go to the engine shutdown checklist if the pressure indication is at or below red line. It wasn't yet; so we waited. As directed; I dumped the center tank fuel. I also spoke with the lead flight attendant; and asked if he had any questions (the Captain had briefly explained the basics to him already). He was concerned about the landing; so I explained that it would be much like a normal landing; that we don't need a lot of thrust on landing; and that he may notice that the deceleration would be more pronounced because we are heavy; and that there would be fire equipment all around us after landing; which is normal. When the oil pressure indication reached redline; I read and the Captain performed the engine shutdown checklist. I then briefed the deferred items. During our final descent; the Captain took control of the aircraft. He directed the other FO to request at least a 15 mile final for an ILS. I finished the fuel dump procedure. Then I balanced the fuel; allowing the load to get 1;000 LBS higher on the side with the operating engine. The Captain briefed the approach and the approach descent checklist from the deferred items were completed. The Captain turned off the auto-pilot when turning final; because we were going to overshoot. He hand flew a great approach and landing; with a normal touchdown. After exiting the runway; the fire trucks approached. They chocked our wheels; and placed large fans next to them to cool the brakes. We shut down and briefed the FAs and passengers. After about 30 minutes; the brake temperatures were back near normal and we were towed to the gate.




Synopsis: A 767 flight crew reported shutting down an engine due to the loss of oil pressure. The appropriate QRH checklist was completed; fuel was dumped; and a successful return to the originating airport was accomplished.
