Synopsis
B777 flight crew reported an engine over heat after takeoff requiring and overweight landing at the departure airport.
Narrative
Aircraft assigned to ZZZZ was a B model 777 which was a change from recent flights I have done to ZZZZ. I believe a C model is much better suited for ZZZZ from ZZZ. ATC refused to accommodate a takeoff with a headwind on XXL. So with a tailwind of 4 knots not much. We could only get numbers for runway XYR max thrust packs off. Packs off is unusual in the 777. It was a very hot day. No other runways available would come up with takeoff numbers. We were cleared for takeoff and as I pushed heading select that the Captain (pilot flying) called for to follow the assigned departure route the Relief Pilot noticed engine overheat. We all looked and noticed a temperature well over the top of the redline and the whole dial was red also. Captain [requested priority handling]. The Captain wisely put the autopilot on and started flying only as we are trained to do and had the Relief Pilot and I run the engine overheat checklist; and get the packs on for the packs off checklist; and the after takeoff checklist. After he reduced thrust on the bad engine it not immediately but eventually cooled down. We asked for a holding pattern and received about four different ones from ATC at 5000 feet. Captain then transferred flying duties to me and I focused on maintaining the holding pattern which was not easy as ATC kept changing it about four times. After the Captain consulted via satcom with Dispatch; Chief Pilot and Maintenance Control he determined that we would land overweight back into ZZZ. We exited holding and built the approach to XYR. Captain took back over flying duties and landed. We rolled out all the way to the end of the runway and exited [taxiway] 1 and parked clear of the runway. Fire and rescue chalked the tire and we pulled up the brake synoptic which showed temperatures climbing. Fire the kept spraying the brakes for about maybe an hour until they were cooled. While we were parked there I noticed magically that airport swapped to landing into the wind on XXCLR. The tiny Fire and Rescue chalks were stuck under the 777. So we had to call a second normal tug out with a tow bar to get them out. Then the super tug towed us to the gate.
Second reporter narrative
On Day 0 I was assigned as a Relief Pilot for flight; ZZZ-ZZZZ. All preflight planning and procedures were normal. The flight pushed back from the gate and taxied to runway XYR and took off without incident. Captain was flying. On climb out at approx 200' AGL the right engine EGT indicated full red; box number and scale; exceeding limits. We continued climbing and [requested priority handling] while getting vectors. The captain reduced the thrust lever on the right engine until the EGT indicated back within normal range as we climbed to 3000' and held. We accomplished all appropriate checklists and coordinated with dispatch and maintenance control and agreed to return to ZZZ as the safest course of action. Maintenance suggested not to dump fuel because 'it had to be inspected upon landing anyway;' so dispatch ran the numbers and we were within limits for landing on XYR. We briefed the flight attendants with their test information and asked them to prepare the cabin. The overweight landing checklist dictated flaps 25 landing which was accomplished safely and without incident. After clearing the runway and coming to a stop; a Brake Temp EICAS message appeared. We accomplished the brake temp checklist and coordinated with crash; fire and rescue to be monitored until the break temps cooled enough to have the aircraft safely towed back to the gate. Once all brakes were cleared we were attached to a ground tug and towed back to the gate where the passengers were deplaned via jet bridge safely and without incident.
