The Byford Dolphin Incident: A Gruesome and Graphic Drilling Rig Accident in the North Sea

TLDR The Byford Dolphin Incident in 1983 involved explosive decompression during saturation diving, resulting in the death of four divers. The incident was caused by faulty equipment, leading to new safety measures being implemented.

Timestamped Summary

00:00 The Byford Dolphin Incident was a gruesome and graphic drilling rig accident involving explosive decompression during saturation diving in the North Sea in 1983.
02:04 Saturation diving allows workers to stay pressurized while working and living on a ship, eliminating the need for daily decompression.
04:02 Saturation diving requires careful pressurization and sealing of the diving bell and ship chamber to maintain the high pressure environment, allowing divers to live and work underwater for extended periods of time.
06:05 On November 5th, 1983, a team of four divers were working in the frig gas field in the North Sea when an incident occurred involving two divers in a bell.
08:12 The diving bell was unclamped from the trunk before the hatch had been shut, causing the pressurized dive chambers to rapidly decompress, resulting in a catastrophic incident.
10:28 The explosion caused by the rapid decompression killed all four divers, with one diver being pulled apart and his remains exploding through a narrow gap in the chamber door.
12:48 The incident was caused by faulty equipment, not human error, and as a result, new specifications were put in place to prevent it from happening again.
