All changed for North Sea training now unfortunately.In fact the one that the civvies use at Aberdeen for North Sea training was far worse. Worse than the new RN one at Yeovilton. Chilled salt water for one thing, waves, and wind courtesy of movie fans. And in the dark.
Still reckon the submarine escape trainer would have had the edge. Just out of interest if the directing staff/ divers saw someone bottling it and not breathing out how did they deal with it. ? Stop them. ? Punch them in the guts.?
My ex crewman ran the VL dunker and I watched a bunch of rock apes in there one day. Totally bottled it. The divers could grab someone by the scruff of the neck and pull them in to the air bubble at the back of the module if need be.
The water work for your BOSIET is pure vanilla. No waves, no darkness, staff divers in the water to pull non-swimmers to the side once they have evacuated the chopper. Only 4 trainees at a time in the cab.
I know elf n safety says you have to be careful when you do training but talk about setting people up to fail!
Reality is 19 seats in a typical offshore helo, crammed in like sardines and if you had to escape and weren't by the window you would be getting kicked black and blue by the person getting out of the window. As for non-swimmers, they would panic like mad as you don't get staff waiting to escort you to the liferaft it were to happen for real.
