The diving system on the Byford Dolphin consisted of several hyperbaric chambers connected to a diving bell. Divers would live and work under pressure in these chambers, and the diving bell would transport them to and from the work site on the seabed. On that fateful day, a critical procedure was underway: the transfer of divers from the living quarters, the hyperbaric chambers, to the diving bell for their final ascent. This transfer required precise coordination and adherence to strict protocols to maintain the integrity of the pressurized environment. The incident occurred when a clamp connecting the diving bell to the hyperbaric chamber was prematurely opened while the system was still under immense pressure. This seemingly small error had catastrophic consequences, creating a rapid and uncontrolled decompression event. The sudden pressure drop caused the divers' body fluids to vaporize almost instantly, a horrifying phenomenon known as explosive decompression. The force of the decompression was so violent that it resulted in the immediate death of four divers, while a fifth diver, who was in the trunking connecting the chambers to the deck, also perished. The sole survivor was a dive tender who was outside the chamber complex at the time of the incident. The details of that day are etched in the memories of those who worked in the offshore industry.
