It was not possible to determine why this had happened, since one of the diving assistants died in the accident.

Saturation divers are professional deep-sea divers who descend to depths of feet meters or more to service equipment on offshore oil rigs and undersea pipelines. But unlike most commercial divers, who do a few hours of work underwater and return to the surface, saturation divers will spend up to 28 days on a single job, living in a cramped high-pressure chamber where they eat and sleep between shifts. And it can be dangerous. In , four saturation divers and one crew member were killed in a gruesome accident aboard a Norwegian-operated oil rig called the Byford Dolphin. The Byford Dolphin catastrophe was a wake-up call for the commercial diving industry, which responded with tighter safety measures to ensure that no one else would meet such a terrible fate.

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. Built as Deep Sea Driller , it was the first-of-class in the highly successful Aker H-3 series, designed by Aker Group and completed at the Aker Verdal shipyard in Byford Dolphin had an overall length of It had a maximum drilling depth of 6, metres 20, ft , and it could operate at a water depth of metres 1, ft. Byford Dolphin was able to maneuver with its own engines to counter drift and ocean currents , but for long-distance relocation it had to be moved by specialized tugboats.

Get the App. Nor were all the internal chamber doors locked. The most infamous example of this is the Byford Dolphin explosive decompression accident. The locking device was opened screwed off before the door into the chamber had been closed and pressure in the tunnel was reduced. Search for images Search for stock images, vectors and videos. Four saturation divers and two tenders were working below the surface of the water when a large explosion occurred. The locking mechanism failed and the bell was blasted with great force away from the chamber. These excursions are measured between disconnection from and reconnection to the pressure chamber. But instead of the chambers flying away, the diving bell did. Join Imgur Emerald to award Accolades! Expand All Expand.

The official inquiry report NOU suggested that the divers involved in the accident had been subject to an inappropriate work routine during the time immediately before the accident. What caused the explosion and what was the fate of these 6 divers? Without these words. As a drilling rig, Byford Dolphin was equipped with advanced drilling equipment and originally met strict levels of certification under Norwegian law, though in later years, it was banned from Norwegian waters. This week we have a highly requested topic: the Byford Dolphin Diving Bell accident. The two dive were tenders William Crammond 32 and Martin Saunders. In a flash, 4 out of out 6 divers were dead and one of the diver tenders was fatally injured. The diving bell is attached to the chamber system by the dive tenders. The locking mechanism failed and the bell was blasted with great force away from the chamber. Grouped together, these risks result in saturation diving becoming one of the most specialized jobs in the world. The locking device was opened screwed off before the door into the chamber had been closed and pressure in the tunnel was reduced. Several strict regulations are enforced to minimize the risks of these issues, from mandatory diving times to forced time-off. Join Imgur Emerald to award Accolades! Because the chambers are near the surface, the pressure on the outside of the chamber is only 1 atm. It was not possible to determine why this had happened, since one of the diving assistants died in the accident.
