What happened to the diver in last breath?

It relates the story of a serious saturation diving accident in 2012, when diver Chris Lemons had his umbilical cable severed and became trapped around 100 metres under the sea without heat or light, and with only the small amount of breathing gas in his backup tank.

Why divers must breathe out as they rise to the surface?

As the diver ascends, the pressure decreases. According to Boyle’s Law, this causes an increase in the volume of the lungs. The diver needs to exhale to adjust for the change in volume caused by the change in pressure.

Do Saturation divers live underwater?

As a saturation diver, you are submerged in the water in a small pressurized chamber. The diver lives for 28 days in this small topside chamber. It is pressurized to the same level as the underwater construction environment, so divers do not have to decompress after each shift.

What does a saturation diver do?

Saturation diving is diving for periods long enough to bring all tissues into equilibrium with the partial pressures of the inert components of the breathing gas. It is a diving technique that allows divers working at great depths to reduce the total time spent undergoing decompression.

How much do North Sea saturation divers make?

However divers working regularly on offshore wind projects can earn up to £100,000 a year. Offshore divers in Scotland can earn around £600 a day. On average, they work around 120-150 days a year. Experienced saturation divers working offshore can earn £1,500 a day or more.

What do saturation divers do?

What happens if you swim to the surface too fast?

Depending on where the bubbles are, you could have a heart attack or a stroke. Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen.
