The Day the Dynamic Positioning System Failed: A Near-Fatal Dive

The life of a commercial saturation diver is inherently dangerous, involving long periods living in a pressurized habitat (the saturation system) to allow for extended work at extreme depths. In September 2012, Chris Lemons was performing routine work on a subsea structure 300 feet (approximately 90 meters) below the surface of the North Sea.

The dive was taking place beneath the support vessel, the Bibby Topaz. The critical component in this operation was the vessel's Dynamic Positioning (DP) system, a computerized system that automatically maintains the ship's position using thrusters.

A catastrophic failure of the DP system occurred, causing the vessel to drift violently in the high winds and rough seas. This sudden, uncontrolled movement resulted in the worst-case scenario: Lemons' umbilical—the lifeline providing him with breathing gas (a helium-oxygen mix), hot water to heat his suit, and communications—was snagged and severed.

Instantly, Chris was plunged into silence and darkness. The loss of his hot water supply meant the frigid North Sea water began to rapidly drop his core body temperature, while the loss of his breathing gas meant his emergency bailout supply was his only hope.

The 28-Minute Miracle: How Chris Lemons Survived

Chris Lemons was left stranded on the seabed, completely cut off from his support team and air supply. His emergency bailout bottle of breathing gas was designed to last only a few minutes, enough time for a rapid, controlled ascent under normal circumstances.

He was at a depth where an immediate, uncontrolled ascent would have been fatal, causing decompression sickness (the bends) or other severe barotrauma. He was forced to conserve his limited air supply while his body temperature plummeted.

The rescue attempt was a frantic, high-stakes operation involving the remaining dive team members, including his supervisor, Dave Yuasa, and diver Duncan Allcock. They had to fight against the drifting vessel and the immense pressure of the deep to reach him.

By the time a rescue diver reached Lemons, he had been without a steady air supply for nearly 30 minutes. His body was cold and unresponsive, showing no signs of life. The rescue team's quick action, combined with a crucial, lucky break in the form of a functioning emergency beacon, allowed them to locate him in the darkness.

The scientific explanation for his survival is complex, but it is believed that the extreme cold of the water may have induced a state of hypothermia that slowed his body's metabolic rate, reducing his oxygen demand. This, combined with his exceptional training and the dedication of his team, resulted in his miraculous resuscitation and survival.
