IamA oil rig working offshore in the northern North Sea AMA!
I've seen a few of these AMA's based around America but there can be quite a different culture between the UK and US offshore environment. I work offshore out of Aberdeen in Scotland. I have been to a few different rigs and seen lots of different ops. I will try to answer as many questions as I can but internet is a tad slow out here.

EDIT: haha just seen I missed a key word out of the title... I am in fact a worker on said oil rig...I'm not an actual oil rig on reddit. Sorry to disappoint....
