The Oil Rig Divers Stopped Working Below 300 Feet — Nobody Ever Said Why

In September 1979, a diving contractor on a North Sea oil platform rewrote its rules overnight. From then on, no diver would work below 300 feet on that structure. Its saturation divers routinely worked far deeper, so why draw the line there? The supervisor who signed the change had spent more than ten years offshore. All deeper work went to an underwater robot that failed about as often as it worked. No reason was ever written down. One diver finished his decompression and never worked offshore again. What happened to him at 320 feet that night? The 300-foot line wasn’t a limit of the human body or the equipment. So what was it a limit of, and what was waiting just below it? #NorthSea #OilRig #SaturationDiving #DeepSea #OceanMysteries #CommercialDiving #UnexplainedOcean #Megalodon This video is a dramatized story inspired by real ocean science and offshore history.
