They help in retracting and unspooling the thick air supply tube lines and communication wires that help link divers to the surface. How Stuff Works notes that a supportive job is played by workers known as tenders. When it was completed, the oil rig had the most updated drilling equipment during this time. As per the Daily Science Journal, the structure was made to work in depths that go as deep as 1,500 feet. This famous accident involved the titular Byford Dolphin, which was a column-stabilized and semi-submersible Norwegian-operated oil rig. To prevent decompression sickness, saturation divers are advised to slowly make their ascent, take regular breaks, and let the body naturally expel nitrogen. This is when divers are at risk of falling into decompression sickness, which is a painful and potentially deadly condition that may lead to grave muscle and joint pain, paralysis, delirium, stroke, and cardiac arrests. If this happens, the molecules of nitrogen that dissolved under pressure quickly grow and turn gaseous once more.īubbles of nitrogen may form in the bloodstream and disrupt blood circulation. The issue surfaces if divers quickly shift from high-pressure conditions to lower-pressure areas. They will have to stay in a chamber that is cramped and high-pressure, where they sleep and eat across shifts.īecause of their exposure to high-pressure conditions, these divers are vulnerable to decompression sickness, which protocols have been trying to protect them against.ĪLSO READ: Deadliest Space Tragedies: 5 Worst Disasters in History of Space Race What Is Decompression Sickness?Īccording to IFL Science, decompression sickness, or "the bends," is a major issue faced by these divers.

Unlike other professional divers who spend a couple of hours underwater before going back to the surface, saturation divers may take as long as 28 hours for a single job. While the job is quite well-paying, it is also considered as one of the most dangerous jobs out there. They do so in order to service equipment on undersea pipelines or offshore oil rigs. How Stuff Works notes that saturation divers are professionals who delve into the depths that go as deep as 152 meters or more. (Photo : Pixabay ) What Do Saturation Divers Do?
