In a similar situation a few years back, with a freshly minted CPL(H), and before the North Sea companies stopped recruiting post 9/11, I got an invitation to go up to Aberdeen for a couple of days to see if I liked the life....
First day - up early (can't remember how early), go and check...whatever needed checking, and put on immersion suit for flight. Sit on jumpseat and wait for passengers, and even I can feel how much they just don't want to be there. Fly out to oil rig. Land on oil rig. Just about enough time for me to get photos of oil rig, and pilots to collect their food - the highlight of the day...how much cake are we getting is the main excitement. Fly back to Aberdeen.
Second day - ditto, with different pilots, and to another oil rig, though I wouldn't have known the difference, as it's all flying straight and level over grey sea beneath grey sky. Conversation goes like this...
Captain: You don't want to do this; you'll be bored.
Whirly: Really?
Captain: I'm bored. (To FO) Are you bored?
FO: Yep, I'm bored.
A few questions by Whirly, and what they mean is that one oil rig is much like another, and occasionally in bad weather it's too exciting, but mostly...it's boring.
Aberdeen is cold and depressing; I return home having enjoyed my few days break, but not at all sure I'd like to spend my life doing it. Didn't have to decide, as oil companies stopped recruiting about the next day!
Now, there must be some people around who know more than this!
