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. Before we explain what happened, here's a little info on decompression sickness or "the bends. Since scuba diving was first invented in the s, divers have learned a lot about how to safely swim to great depths, sometimes the hard way. As a diver descends, the weight of the water around them applies pressure to every cell in their body.

What caused the explosion and what was the fate of these 6 divers? One dive tender, Martin Saunders, survived and the other, William Crammond, was fatally injured and would later die during transport to a nearby hospital. The diving bell is attached to the chamber system by the dive tenders. After the hatches are sealed and there are no leaks, the trunk is then slowly depressurized to 1 atm. Following an investigation, the Norwegian Petroleum Directorate concluded that the direct cause of the accident was that the locking device connecting the bell with the chamber system was unlatched while the system was still under pressure. Pressure was lost in the chamber system within seconds, and all four divers inside were killed instantly. From the chamber, the saturation divers enter the diving bell and take it to the seafloor where they can begin their work. 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. A report showed there were 3, commercial divers working in the United States. These saturation divers leave the safety of dry land and enter pressurized living quarters, after which they are transferred down to an underwater habitat via a diving bell. The most infamous example of this is the Byford Dolphin explosive decompression accident.
