The Byford Dolphin: A Brief Overview

The Byford Dolphin was a semi-submersible drilling rig owned by Comex Services and operated by Stavanger Drilling. It was a state-of-the-art rig at the time, capable of drilling in deep waters and withstanding harsh weather conditions. However, even the most advanced technology is vulnerable to human error and systemic failures, as the Byford Dolphin incident tragically demonstrated.

The rig operated primarily in the North Sea, a region known for its challenging conditions and demanding drilling operations. The Byford Dolphin was involved in numerous projects throughout the 1970s and 1980s, contributing to the burgeoning offshore oil and gas industry. Before the incident, the rig had a relatively unremarkable safety record, lulling some into a false sense of security.

The Fateful Day: November 5, 1983

The Byford Dolphin incident occurred on November 5, 1983, while the rig was connected to the Statfjord field pipeline system. A team of divers was working in saturation diving, a technique that allows divers to work at great depths for extended periods. Saturation diving involves pressurizing the divers’ living quarters and the diving bell to the pressure equivalent to the depth at which they are working. This eliminates the need for lengthy decompression periods after each dive.

At the time of the incident, four divers – Edwin Arthur Coward, William Crammond, Roy Lucas, and Bjørn Giæver Bergersen – were in the diving system, which consisted of a diving bell and a series of chambers. Two support personnel, Martin Saunders and Arild Bådsgård, were on the rig, responsible for managing the diving operation.

The Chain of Events Leading to Disaster

The incident was triggered by a premature disconnection of the diving bell from the diving system. This disconnection was initiated to allow the divers to be transported back to the surface. However, standard safety procedures were not followed, leading to a catastrophic sequence of events.

* **Premature Disconnection:** The diving bell was disconnected before the pressure in the diving system was equalized with the surrounding water pressure. This was a critical error, as it created a massive pressure differential.
* **Explosive Decompression:** As the bell was disconnected, the sudden drop in pressure caused an explosive decompression within the diving system. This decompression was so rapid and violent that it had devastating consequences for the divers.
* **Human Error:** The investigation revealed that a combination of human error, inadequate communication, and insufficient training contributed to the premature disconnection. The diving supervisor, under pressure to complete the operation quickly, bypassed several safety checks.
