Understanding the Byford Dolphin Incident

The Byford Dolphin was a semi-submersible mobile drilling rig operating in the North Sea. On that fateful night, the rig was connected to the Statfjord field via a diving bell system. Four divers were in the habitat system, preparing for a saturation dive. What followed was a catastrophic decompression event that claimed the lives of all four divers and a dive tender.

Saturation Diving: The Context

Saturation diving is a technique used in offshore operations where divers live in a pressurized environment for extended periods. This allows them to work at great depths for longer durations, eliminating the need for repeated decompression. However, it also introduces significant risks, as the body becomes saturated with inert gases like helium. Rapid decompression can lead to severe decompression sickness, also known as “the bends,” and in extreme cases, death.

The Sequence of Events

The tragedy unfolded during a routine procedure. The diving bell, which connected to the habitat chambers via a trunk, needed to be detached. A clamp, designed to ensure a tight seal between the bell and the trunk, was prematurely opened before the pressure was equalized. This created a massive pressure differential, causing an explosive decompression within the habitat chambers. The pressure went from 9 atmospheres to 1 atmosphere in fractions of a second.

The Victims

The four divers who perished were Edwin Arthur Coward, William Crammond, Ronald McKenzie, and Roy Lucas. The dive tender on the deck, Curtis Rugland, was also killed. The incident caused immense grief and highlighted the inherent dangers faced by those working in the offshore diving industry.
