In 1983, a tragic accident on the Byford Dolphin oil rig resulted in explosive decompression, home SPO2 device immediately killing 4 saturation divers and critically injuring one other crew member. The speedy decompression occurred when a diving bell prematurely detached from its chamber resulting from unsealed chamber doors. The incident revealed extreme flaws in security protocols and led to important enhancements in business diving operations and safety standards worldwide. Saturation divers are professional deep-sea divers who descend to depths of 500 ft (152 meters) or more to service gear on offshore oil rigs and undersea pipelines. But not like most business divers, who do a number of hours of labor underwater and return to the surface, saturation divers will spend up to 28 days on a single job, dwelling in a cramped excessive-stress chamber where they eat and sleep between shifts. Pay is nice for saturation divers - between $30,000 and $45,000 a month - however it's intense work in an otherworldly and claustrophobic atmosphere.

And it may be harmful. In 1983, 4 saturation divers and BloodVitals home monitor one crew member have been killed in a gruesome accident aboard a Norwegian-operated oil rig referred to as the Byford Dolphin. Life support technicians ensure the air combine in the hyperbaric chamber matches the air that the divers breathe underwater. The dive management workforce is in control of working the diving bell - which raises and lowers on a crane - and monitoring the divers as they work. There are even cooks who put together and serve meals to the men cooped up within the living chambers. They assist unspool and retract the "umbilical," the thick line of air supply tubes and communication wires that connect the divers to the floor. In the past, tenders had different responsibilities that included docking the diving bell to the pressurized residing chambers. Phillip Newsum, BloodVitals home monitor an skilled industrial diver and executive director of the Association of Diving Contractors International.

On Nov. 5, 1983, an skilled tender named William Crammond was in the middle of a routine process aboard the Byford Dolphin, a semi-submersible oil rig working in the North Sea. The rig was equipped with two pressurized dwelling chambers, BloodVitals home monitor each holding two divers. Crammond had simply linked the diving bell to the living chambers and safely deposited a pair of divers in chamber one. The other two divers had been already resting in chamber two. That's when things went horribly incorrect. Under normal circumstances, the diving bell wouldn't be detached from the living chambers till the chamber doors have been safely sealed shut. The air pressure inside the Byford Dolphin living chambers immediately went from 9 atmospheres - the strain skilled whereas a whole lot of ft under the water - to 1 ambiance, the normal air strain on the surface. The explosive rush of air out of the chamber sent the heavy diving bell flying, killing Crammond and critically injuring his fellow tender, Martin Saunders.

The destiny of the four saturation divers inside was far worse. Based on autopsy studies, three of the men contained in the chamber - Edwin Arthur Coward, Roy P. Lucas and Bjørn Giæver Bergersen - had been essentially "boiled" from the inside when the nitrogen in their blood violently erupted into gas bubbles. The fourth diver, Truls Hellevik, suffered the grizzliest loss of life. Hellevik was standing in front of the partially opened door to the residing chamber when the strain was released. His physique was sucked out through an opening so slim that it tore him open and ejected his internal organs onto the deck. As a diver descends, the weight of the water round them applies pressure to every cell of their physique. The pressure even compresses molecules of gaseous nitrogen taken in by the lungs, which causes the nitrogen fuel to dissolve into the bloodstream. The absorption of nitrogen itself isn't the issue. The problem starts if a diver tries to ascend to the floor too rapidly.

Think of it like shaking a 2-liter bottle of soda and opening the cap. The fact that there was no interlock on the locking mechanism was instantly apparent, BloodVitals insights and now the presence of applicable security interlocks on sat diving systems has maybe the best priority of all safeguards," Bryan McGlinchy, diving supervisor on the International Marine Contractors Association (IMCA), tells Energy Voice. "What you’ve bought to do is consider the human being in the system and never put these individuals in a position where an understandable human error may lead to very severe penalties. Our security techniques must be designed to be tolerant of human error. On high of dealing with the loss of life of her husband, Ruth Crammond additionally needed to deal with the aftermath of the investigation. She additionally never believed the Norwegian authorities's findings because of the years of his years of diving experience. The Byford Dolphin was one of many worst oil discipline disasters in history," Newsum says, "and it led to sweeping modifications within the North Sea and Blood Vitals in commercial diving security worldwide.
