The job duties of an offshore nurse involve providing medical care for members of the crew on an oil rig, drillship, or other offshore installation. In this position, you work offshore for several weeks at a time, and you are on call at all times while on the rig. You treat injuries and illness and ensure that the rig has adequate medical supplies. Most offshore facilities do not have doctors, so your responsibilities include performing triage and, if necessary, ordering evacuation when a significant injury occurs. Since your time on the rig can be stressful, you usually get several weeks off in between working periods.
