![]() Fatigue from many hours of hard work also brought casualties among divers, who often worked for 16 hours. At that moment, the only communication the tender made outside the room system was through loudspeakers stuck to the wall with the swift sound of rigs and the sea, it's hard to hear what's going on. It is unclear whether the tender that opens the clamps before the trunk is depreciated does so on the orders of his superiors, on his own initiative, or because of miscommunication. The committee investigating the accident concluded that it was caused by human error on the part of the diving tender that opened the clamp. ![]() The fourth diver was cut into pieces and mutilated by an explosion that forced it out through a partially obstructed door and would die instantaneously. The death of three divers remaining intact in the room will be very fast because the circulation is immediate and completely stopped. It is recommended that the formation of rapid bubbles in the blood denatures the lipoprotein complex, making the lipids insoluble. This fat may not be embolized, but must be precipitated from the blood in situ. The most noticeable autopsy findings are the large amounts of fat in the large arteries and veins and in the heart chambers, as well as the intravascular fat in the organs, especially the liver. Medical investigations were conducted on four divers. It is projected some distance, one part later found 10 meters (30 feet) vertical above the exterior pressure door. and roughly chop, including dividing his thoracoabdominal cavity, which further leads to the expulsion of all the internal organs of the chest and abdomen, except the trachea and small intestine, and thoracic spine. Subsequent investigations by forensic pathologists determined that Hellevik, exposed to the highest pressure gradient and in the process of moving to secure the inner door, was forced through a 60 cm (24 inch) diameter opening made by an interior trunk door jammed by escaping air. Tenders that opened the clamps were killed while others were seriously injured.Ĭoward, Lucas, and Bergersen were affected by explosive decompression and died in the position indicated by the diagram. The air rushed out of the room with tremendous force, pressed the door of the interior trunk and pushed the bell away, hitting both tenders. This results in an explosive decompression of unclosed space. The first two steps have been completed when, for unknown reasons, one of the tenders (Crammond) opens the clamp before Diver 4 (Hellevik) can close the door to the room. Open the clamp to separate the bell from the chamber system.Slowly depressurize the trunk to 1 atmosphere.Close the door between the trunk and space 1. ![]() The diving supervisor will then slightly increase the pressure of the bell to close this door tightly.Letting their wet teeth in the trunk, the diver climbs through the trunk to room 1. Diving bells with Bergersen and Hellevik have just been won after diving and joining the luggage. On this day, Coward and Lucas are resting in room 2 at a pressure of 9 atm. The third space is connected to this system but not involved. This connection is sealed by a clamp operated by two tenders, who are also experienced divers. The situation just prior to this accident is as follows: Decompression chamber 1 and 2 connect via rod to diving bell. One of the tenders, William Crammond, 32 years from the United Kingdom, and the four diver died instantly Another tender, Saunders, was seriously injured. Hellevik wants to close the door between the space system and the rod when the explosive space is decompressed from the pressure of nine atmospheres into one atmosphere. They were assisted by two diving tenders, Crammond and Saunders. The divers are Edwin Coward (England, 35 years), Roy Lucas (UK, 38), BjÃÆ'ørn GiÃÆ'Ãverver Bergersen (Norway, 29) and Truls Hellevik (Norway, 34). On Novemat 4:00 AM, while drilling at the Frigg gas field in the Norwegian sector in the North Sea, four divers were in a decompression space system attached by a rod (short section) to a diving bell on the rig. All the crew were evacuated in the boat of life, but six people were killed when they fell from the boat of their life. On March 1, 1976, the rig foundered in transit from a block in the North Sea to Bergen.
