This video examines underwater diving accidents caused by differential pressure (Delta P) and saturation diving hazards, specifically detailing the fatal incidents involving two experienced divers at the Plate Taille reservoir and the survival story of saturation diver Chris Lemons aboard the Bibby Topaz.

From the video

Answers: What are the most dangerous underwater diving accidents caused by Delta P and saturation diving?

• Differential pressure Delta P diving hazards
• Plate Taille reservoir dive accident
• USS Spiegel Grove artificial reef diving
• Saturation diving safety and procedures
• Bibby Topaz diving vessel operations

What it concludes

• Differential pressure Delta P accounts for two out of every three commercial diving fatalities.
• Divers approaching intake systems while turbines are running face inescapable suction forces known as Delta P.
• Saturation diver Chris Lemons survived 35 minutes without a breathing gas supply at the bottom of the North Sea after his umbilical was severed.
• Ten divers have died on the USS Spiegel Grove artificial reef since it was opened to the public in June 2002.
