S2 E10 Life on a Line - Saturation Diving with Chris Lemons Pt 1

Real Risk

The world of saturation diving is high tech, complex and fascinating. The physics and physiology present unbreakable rules that must be followed to remain safe. The risks of decompression sickness, High Pressure Nervous Syndrome (HPNS), oxygen toxicity and inert gas narcosis are carefully managed. But perhaps the hardest part; living in the confines of the hyperbaric quarters for 28 days with no possibility of early release. You have to be the right kind of person.
In 2012, Chris Lemons was an experienced commercial diver, but relatively new to sat diving. "Sat" is the pinnacle of the job, good pay, exciting work and greatly respected. And he loves it. So when a highly improbable sequence of events occurred on board the ship nearly 100m above him in the middle of the North Sea late one night, he managed the chain of event which followed with a measured calm born of inner strength and years of training. He stayed calm right up until the moment his life support umbilical snapped...he then knew that in approximately 8 minutes his breathing gas would run out and he would die.
