## Understanding the Byford Dolphin Accident
The Byford Dolphin was a semi-submersible drilling rig owned by Dolphin A/S, a Norwegian company. On November 5, 1983, while operating in the Frigg oil field in the Norwegian sector of the North Sea, the rig was the site of a decompression accident that claimed the lives of five men. The incident involved divers working in a saturation diving system, a technique used for deep-sea diving where divers live in a pressurized environment for extended periods.
### The Saturation Diving System
Saturation diving allows divers to work at great depths for longer durations. The divers live in a pressurized chamber, typically a deck decompression chamber (DDC), and are transported to and from the work site in a diving bell. The pressure inside the chamber and the bell is maintained at the same level as the working depth, allowing the divers to avoid the time-consuming process of decompression after each dive. However, saturation diving is inherently risky, requiring strict adherence to safety procedures and precise control of pressure.
### The Sequence of Events
The Byford Dolphin accident occurred during a routine procedure. The divers had completed their work and were returning to the DDC. The diving bell, containing two divers, was successfully mated to the DDC. However, a critical error occurred during the process of disconnecting the bell from the DDC. One of the diving supervisors prematurely opened a clamp that secured the bell to the DDC *before* the pressure inside the DDC and the bell was equalized. This resulted in a massive and instantaneous decompression of the DDC, with devastating consequences.
### The Instantaneous Decompression
The rapid decompression caused the pressure inside the DDC to drop from 9 atmospheres (approximately 297 feet of seawater) to 1 atmosphere (sea level pressure) in a fraction of a second. This sudden pressure change created an explosive force that ripped through the chamber, instantly killing the four divers inside. One support worker, who was assisting with the procedure, was also killed. The violence of the decompression was so extreme that one of the divers was partially ejected through the small, 60 cm (24 in) diameter, opening of the clamping system, his body exploding due to the decreasing ambient pressure.
## Contributing Factors and Causes
The Byford Dolphin accident was not simply the result of a single error. A combination of factors contributed to the tragedy, including human error, equipment failure, and inadequate safety procedures. A thorough investigation revealed several key contributing factors:
* **Human Error:** The premature opening of the clamp was the immediate cause of the accident. This error was attributed to a lack of communication, inadequate training, and a failure to follow established procedures. It’s important to note that fatigue and stress, common in the demanding offshore environment, may have also played a role.
* **Equipment Failure:** While not the primary cause, the design of the clamping system contributed to the severity of the accident. The system lacked sufficient safeguards to prevent accidental opening under pressure. Furthermore, the rapid-closing non-return valve, designed to prevent backflow, was installed incorrectly, rendering it useless.
* **Inadequate Safety Procedures:** The investigation revealed shortcomings in the safety procedures and training programs related to saturation diving. There was a lack of clarity regarding responsibilities and a failure to adequately address potential hazards. The absence of a clear checklist and verification process further exacerbated the problem. Our experience indicates that redundancy in critical safety systems is paramount.
* **Communication Breakdown:** A breakdown in communication between the diving supervisor and the other members of the diving team contributed to the error. Clear and concise communication is essential in high-risk environments like saturation diving.
## The Aftermath and Investigation
The Byford Dolphin accident triggered immediate shock and grief within the offshore oil and gas industry. A comprehensive investigation was launched to determine the causes of the accident and to prevent similar tragedies in the future. The investigation was conducted by the Norwegian Petroleum Directorate (NPD), the government agency responsible for regulating the petroleum industry in Norway.
The NPD’s investigation involved a detailed examination of the accident site, interviews with surviving personnel, and a review of relevant documentation. The investigation concluded that the accident was caused by a combination of human error, equipment failure, and inadequate safety procedures. The NPD issued a series of recommendations aimed at improving safety in saturation diving operations. These recommendations included:
