Roustabout
Roustabouts perform routine physical labor and maintenance on oil rigs and pipelines. The recent Deepwater Horizon oil-rig disaster, which killed 11 workers, demonstrates the dangers these workers face. The hours are long, usually 12 hours on and 12 hours off, and the locations are so isolated that most roustabouts can leave the rigs only every two weeks or so.
