I did watch both episodes last night.
1. Burnt hand - it happens. I am not sure why the guy needed evacuation, but communicating with the frigate and the boat transfer were useful training.
2. Refrigeration leak - it seemed odd that they captured the gas in a plastic bag.
3. Fire in engine room - seemed odd, no signs of water or foam being used. There were guys in white overalls with clipboards, which made me wonder If it was a training exercise.
4. Problem with air scrubbers - another training serial? After it was fixed the atmosphere was back to normal very quickly and EBS sets removed.
5. Coordinated operations working with HMS Sutherland - quite a big thing, either in British waters working with the Fleet Ready Escort and/or Towed Array Patrol Ship (and her helicopter, or possibly Maritime Patrol Aircraft), or as part of a deployed task group.
