One of the most compelling parts of the exhibit is its section on oil platform workers. Typically glossed over in drilling debates, these employees, about 100 or so per rig, occupy a self-contained city perched 16 stories above the waterline. They typically work 12 hours a day for seven days straight (called a “hitch”) followed by seven days off. Each member of a drilling crew has a specific task. Roughnecks work directly on the rig floor. Pit hands keep an eye on mud conditions and maintain the machinery. Roustabouts unload pipes and supplies from boats and perform cleanup. Tool pushers supervise the drillers, who bore the wells.
