Synopsis
Air Carrier flight crew reported while in cruise receiving engine oil temperature warning resulting with the air crew landing safely at the first available airport.
Narrative
Occurrence time is my estimate. Refer to CA or FO report for more precise info. I had almost started to sleep as relief pilot on first break in the crew rest area; when my fellow Relief Pilot 'wakes' me; and tells me they shut down an engine. He had not yet finished getting ready in his bunk; and re-entered the cockpit before me. I quickly dressed and re-entered the cockpit; hooked up headset; etc. as the CA and FO started the fuel jettison non-normal checklist. They had already shutdown the right engine; etc.; before I re-entered the cockpit. I assisted by talking with Dispatch on SATCOM; relaying for crew. We decided not to pass over the suitable alternate of ZZZ. Dispatch provided ZZZ weather; and the previously requested landing data messages (LDM's). Because it took a while before the LDMs showed up on the printer; I referred to the 200B Non-normal landing distance table; calculating for ENG SHUTDOWN L; R (Flaps 20). I rounded up our actual gross weight to 480.0 to minimize extrapolation and derived a required landing distance of 4800 feet. My fellow Relief Pilot Q-C'd my calculation. We were happy I did the calculation; because Dispatch sent up LDMs only for flaps 30 and flaps 25. We compared my number to those from Dispatch for good measure and we agreed autobrakes 4 would be sufficient. (And they were.) I backed up the PF and PM; etc. and conferred with my fellow Relief Pilot as necessary. I also assisted communicating with the purser; updating our status and estimated landing time; etc. Our CRM seemed professional and effective to me and us as a crew. Our training kicked in very nicely. We backed each other up. The CA had set an open tone from the start of our flight brief and maintained it throughout the entire flight. He effectively managed time-critical tasks and delegated appropriately. As a crew we freely tested assumptions amongst each other. ATC; ZZZ tower; ground; all supported us in excellent fashion. Passengers thanked us for getting them to ZZZ safely.
Second reporter narrative
The Relief Pilots had just left to start there break and we had leveled off at FL330. A few minutes had passed and we noticed a high oil temperature warning. Person 1 went to the checklist and started going through the steps. I had brought the thrust lever back slowly but the temperature keep getting hotter. Person 1 and I both looked at each other and decided we needed to land the plane at the nearest suitable airport ZZZ. Person 1 notified ATC we were [requesting priority handling] and going to ZZZ; I call the purser and told her we needed the Relief Pilot back up front and to prepare the cabin for a landing in ZZZ. We followed the checklist. We shut down the engine and started dumping fuel to get below landing weight. I believe it took between 25 and 30 minutes to get everything prepared before I made the landing in ZZZ. We told ATC to have emergency crews standing by. I made a single engine flaps 20 landing. It went smooth and we taxied to the end of the runway and then taxi to the holding area and ground crews had told us there was no fire just a little bit of smoke and a little fluid coming out of the right engine. There was no need to do an evacuation so we asked to passengers to remain seated until we could get things situated. Coordinated with company to have buses come out to the aircraft and air stairs to deplane passengers which took probably 30 minutes. The crew was awesome!
