People who work on the rigs are at the sharp end of the business.
The rig workers on the left are attaching sections to a drill. The drill drives deep into the sea bed to reach the oil in the undersea wells.
Like most of the platform crew, they spend two weeks on the platform and three weeks off. Whilst offshore, they work back to bakc twelve hour shifts.
The work is hard, but the pay is good and the time spent onshore makes up for the two weeks away.
