You will generally work on offshore vessels, platforms, rigs and marine laboratories, with some of your work taking place in coastal facilities. This will involve periods of time away from home, usually a few weeks to a month at sea, working long shifts, followed by a number of days off work. You will likely work alongside people of various nationalities and spend substantial time outside, operating ROVs from the deck of a vessel or platform.
An ROV is a remotely operated vehicle. The people who operate them are referred to as pilots and they direct ROVs to carry out tasks in underwater environments that are often too deep or too dangerous for human divers.
