I would assume rig meals are still a normal part of North Sea ops. I was there at a similar time to FED, and flew with him, and round trips to the East Shetland Basin with RR refuel in Sumburgh each way could easily be over 7 hours. Even shorter flights like the Beryl (4:15?) or Brae (3:45) would be tied to another flight, the total hours would be quite high. So getting a decent full fried was the main attraction!! In the Southern North Sea it was bacon and egg rolls in the morning - much shorter sectors but still back to back trips could add up to several hours.
