The five divers who died in the accident were:

Roy Bennett, 34, diver
Michael Bevan, 27, diver
William Crammond, 34, diver
Duncan Elliot, 35, diver
Trevor Morgan, 41, diver

The six divers who were injured in the accident were:

Robert Campbell, diver
Victor Clark, saturation technician
David Cox, diver
David Kirby, diver
John Street, diving supervisor
Roy Westwood, commercial diver

The Byford Dolphin diving accident was one of the worst diving accidents in British history. It led to a number of changes in the way that diving operations are conducted in the North Sea.

The Byford Dolphin diving accident was one of the worst diving accidents in British history. It led to a number of changes in the way that diving operations are conducted in the North Sea.

Cause

A sudden influx of water was the cause of the Byford Dolphin diving accident. This occurred when a diving bell was being used to conduct routine maintenance on a drilling rig in the North Sea. The sudden influx of water caused the diving bell to descend rapidly to the seabed, resulting in the deaths of five divers and injuries to six others.

Sudden influxes of water can occur for a variety of reasons, including:

Equipment failure
Human error
Environmental factors

In the case of the Byford Dolphin diving accident, the sudden influx of water was caused by a combination of equipment failure and human error. A valve in the diving bell malfunctioned, allowing water to enter the bell. The diving supervisor then failed to take immediate action to stop the flow of water, which resulted in the bell becoming flooded.

Sudden influxes of water are a serious hazard for divers. They can lead to drowning, decompression sickness, and other serious injuries. Divers must be aware of the risks of sudden influxes of water and take steps to prevent them from happening.

1. Location

The Byford Dolphin diving accident occurred in the North Sea, approximately 120 miles (190 km) northeast of Aberdeen, Scotland. The North Sea is a marginal sea of the Atlantic Ocean, located between Great Britain, Norway, Denmark, Germany, the Netherlands, Belgium, and France. It is one of the busiest shipping areas in the world, and is also home to a large number of offshore oil and gas rigs.

Environmental conditions: The North Sea is a challenging environment for diving operations. The water is cold, dark, and often murky. There are also strong currents and tides. These conditions can make it difficult to see and navigate, and can also increase the risk of decompression sickness.
Shipping traffic: The North Sea is one of the busiest shipping areas in the world. This means that there is a high risk of collision between diving vessels and other ships. Divers must be aware of the shipping traffic in the area and take steps to avoid collisions.
Oil and gas operations: The North Sea is home to a large number of offshore oil and gas rigs. These rigs can create a number of hazards for divers, including:
- Subsea pipelines and cables
- Diving bells and other diving equipment
- Chemical spills
Divers must be aware of the hazards associated with oil and gas operations and take steps to avoid them.

The Byford Dolphin diving accident was a tragedy that claimed the lives of five divers. The accident highlights the dangers of diving in the North Sea. Divers must be aware of the environmental conditions, shipping traffic, and oil and gas operations in the area, and take steps to mitigate the risks.

2. Date

The Byford Dolphin diving accident occurred on 5 November 1983. This date is significant for several reasons:

Historical context: The early 1980s was a time of rapid expansion in the North Sea oil and gas industry. This led to a corresponding increase in the number of diving operations being conducted in the area. The Byford Dolphin diving accident was one of a number of fatal diving accidents that occurred during this period.
Weather conditions: The weather conditions on 5 November 1983 were poor. There were strong winds and waves, which made diving operations more hazardous. The poor weather conditions may have contributed to the accident.
Equipment failure: The diving bell that was being used in the Byford Dolphin diving accident was relatively new. However, it had a number of design flaws that made it susceptible to failure. These design flaws may have contributed to the accident.
Human error: The diving supervisor on the Byford Dolphin made a number of errors that contributed to the accident. These errors included failing to properly secure the diving bell and failing to take immediate action to stop the flow of water when the bell began to flood.

The Byford Dolphin diving accident was a tragedy that claimed the lives of five divers. The accident highlights the importance of safety in diving operations. It also shows that even the most experienced divers can make mistakes. Divers must be aware of the risks involved in diving and take steps to mitigate those risks.

6. Type of rig

The Byford Dolphin diving accident occurred on a semi-submersible drilling rig. Semi-submersible drilling rigs are large, mobile offshore structures that are used to drill wells for oil and gas exploration and production. They are designed to operate in deep water and can be moved from one location to another.

Stability: Semi-submersible drilling rigs are very stable, which makes them ideal for use in deep water. They are held in place by a system of anchors and ballast tanks. This stability is essential for safe diving operations.
Mobility: Semi-submersible drilling rigs can be moved from one location to another, which makes them versatile. This mobility is important for following oil and gas reserves as they are discovered.
Cost-effective: Semi-submersible drilling rigs are more cost-effective than other types of offshore drilling rigs. This is because they can be used in a variety of water depths and can be moved from one location to another.

The Byford Dolphin diving accident highlighted the importance of using stable and mobile drilling rigs for diving operations. Semi-submersible drilling rigs are well-suited for this purpose, and they continue to be used extensively in the offshore oil and gas industry.
