Everyone who's working offshore today has to have what's called basic survival training. It's a five-day course, and as I mentioned, every offshore worker has to do it. It involves, obviously, a classroom component, learning about different safety facets of working offshore.
It also contains a component where you are in a helicopter escape underwater trainer. It's a simulator where you simulate being in a helicopter that gets ditched in the water. You're in a unit that looks like a helicopter, it's put upside down in the water, and you're taught how to escape.
You're also brought out into the ocean, where you learn how to manoeuvre your body within a survival suit, which every offshore worker has to have when they go offshore. You're also taught how to board a lifeboat and disembark from a lifeboat. You're taught a number of other safety measures.
As I mentioned, this is a five-day course. You get a certificate, and after three years you have to go back and actually get a refresher. This is not a one-time thing in terms of training. You take a five-day course and after three years you have to do it again.
