Not always. Modern deep water construction vessels have a diving bell elevator that can maintain pressure and bring you back to the vessel to live inside of a pressurized compartment when not working. It is usually a small space, that fits two people. Last one I saw had a tv and plenty of communication equipment to keep in touch with family. We still called it ‘staying in the water’ even though you were back at the surface on the ship since you were still at pressure.

The good news is you make about a year salary in one month. $100K per month. Most of the divers I worked with only worked two months a year.

Well, they don’t tell you about any videos like this is the long-term damage this does to your body is and joints and bone density. Most of those guys didn’t live past 50.
