water survival training.

This is an example of a survival training class for offshore workers. They teach hands how to manage in a life boat (black rubber boat with yellow cover in back)

They also teach the hands hot to escape a downed helicopter after it lands on the sea then tips over into the ocean. (blue box in water, it is flipped over here, you must remove the window and crawl out)

they also teach the hands how to swim, use their clothes as floats, and handle themselves in life vest while in the water.
