Decompression sickness

Decompression sickness, also known as "the bends," is a serious diving hazard that can occur when a diver ascends too quickly from depth. During ascent, the nitrogen that has been absorbed into the body's tissues during the dive forms bubbles in the bloodstream, which can block blood vessels and cause damage to tissues and organs. Symptoms of decompression sickness can range from mild joint pain to paralysis and death.

In the Byford Dolphin incident, it is believed that the divers ascended too quickly from a depth of 50 meters (160 feet) to 20 meters (65 feet) in a period of just four minutes. This rapid ascent gave the nitrogen in their bodies insufficient time to be released safely, leading to the formation of bubbles and ultimately to their deaths.

The Byford Dolphin incident highlighted the critical importance of proper decompression procedures in diving. Divers must ascend slowly and make decompression stops at specific depths to allow the nitrogen to be released from their bodies safely. Failure to follow proper decompression procedures can have fatal consequences.

Diving safety

The Byford Dolphin incident was a catalyst for significant changes in diving safety regulations and practices in the offshore industry. In the aftermath of the incident, a number of new regulations were introduced, including:

  • Stricter limits on dive depth and duration: The maximum depth and duration of dives are now limited, based on the diver's experience and qualifications.
  • Improved training and certification requirements: Divers are now required to undergo more rigorous training and certification before they are allowed to work on offshore diving projects.
  • Enhanced emergency response capabilities: Offshore diving vessels are now required to carry more advanced emergency response equipment, including recompression chambers.

These new regulations and practices have helped to improve safety in the offshore diving industry. However, it is important to remember that diving is still a hazardous activity, and divers must always be aware of the risks involved.

Physiological effects

The Byford Dolphin incident highlighted the critical importance of understanding the physiological effects of diving on the human body. When divers descend underwater, the increased pressure exerts a number of stresses on the body, including:

  • Increased nitrogen absorption: At depth, the partial pressure of nitrogen in the breathing gas is increased, which leads to increased absorption of nitrogen into the body's tissues.
  • Compression of body cavities: The increased pressure also compresses the body's cavities, such as the lungs and sinuses.
  • Changes in blood flow: Diving can cause changes in blood flow, which can lead to problems such as decompression sickness and arterial gas embolism.
These physiological effects can have serious consequences for divers if they are not properly managed. For example, if a diver ascends too quickly from depth, the nitrogen that has been absorbed into their tissues can form bubbles in the bloodstream, which can lead to decompression sickness. The Byford Dolphin incident led to a number of studies on the physiological effects of diving. These studies have helped to improve our understanding of the risks associated with diving and have led to the development of new safety procedures and equipment. Today, divers are required to undergo training on the physiological effects of diving before they are allowed to dive. This training helps divers to understand the risks involved in diving and how to avoid them.
