On November 5, , an accident at the Byford Dolphin oil rig, located in the North Sea off the coast of Norway, cost five people their lives in a particularly horrifying way. The incident shocked the public and led to more stringent safety regulations for those diving at inhospitable depths. The event now stands as a cautionary tale for deep-sea divers, who operate at high risk depths. The rig's owners employed four divers and two assistants called dive tenders to perform underwater maintenance via saturation diving, a very risky operation. An error between the divers' pressurized living space and the unpressurized dock caused an explosive decompression, killing all the divers and one of the tenders.

But that interaction failed in this case. Three of the divers died when their blood byford dolphin pics — meaning the expanding nitrogen in their bloodstream turned into air bubbles. To work at such incredible depths while minimizing risks, we have saturation divers.

Byford Dolphin was a semi-submersible , column-stabilised drilling rig operated by Dolphin Drilling , a Fred Olsen Energy subsidiary. It drilled seasonally for various companies in the British, Danish, and Norwegian sectors of the North Sea. It was registered in Hamilton, Bermuda. The rig was the site of several serious incidents, most notably an explosive decompression in that killed four divers and one dive tender, as well as badly injuring another dive tender.

However, in , the cause was found to have been an equipment malfunction, absolving Crammond. Decompressing before coming to the water's surface can take hours or even days, especially if diving deeply. Load 5 more images Chevron Pointing Down. It's an effect similar to the bubbles rising in a pot of boiling water. Load more comments Chevron Pointing Down. This, according to the diver in the video, meant that everyone the habitat had nine times the usual amount of nitrogen in their bodies as they would normally on the surface. Once they are saturated, they will stay under intense pressure and breathe a mixture of oxygen and helium for weeks, until their tour of duty is over and they can be decompressed. The locking mechanism failed and the bell was blasted with great force away from the chamber. Just off to the left of chamber 1 is chamber 2. This involves a living space known as a habitat, which is pressurized to the same level as the water in which the divers work. But November 5th, was anything but normal. The fourth, Hellevik, was forcibly ejected by the escaping gas through a small opening in the door he was trying to close, mutilating his body and scattering appendages across the dock. Options Menu. None of them felt anything.

Imagine working metres beneath the sea, a hostile place that sunlight never reaches and where temperatures can plunge to a few degrees above freezing. All your off hours are spent in a tiny, cramped metal tube, breathing a mixture of gases that makes it hard for you to speak and constantly saps heat from your body, giving you a permanent chill.

Song was a Two Part. It was not possible to determine why this had happened, since one of the diving assistants died in the accident. Amazingly, the other dive tender survived but was severely injured. What is saturation diving? Sign in to leave a comment Sign In Sign Up. This is a more modern photo of a sat diver working ] During saturation diving, your body stays under pressure for so long that all your bodily tissues become in equilibrium with the inert gases in the breathing mixture either helium or nitrogen. But this rapid decompression is on an entirely new level and multiple factors played into how this accident was caused. In a normal sequence of events, the following steps would occur: 1. They contain the same mix of oxygen and nitrogen as air on the surface or sometimes have added helium. That's why divers must slowly come up, a little bit at a time, so the nitrogen can safely expand and decompress. To explain what went wrong, it's vital to understand the dangers of decompression sickness on the human body, saturation diving, and the science behind what happened at the moment of the accident.
