(1)The water pressure in the deep sea is extremely high, so you have to make your body able to withstand this water pressure to dive deep into the sea
(2)Accordingly, deep-sea divers raise the pressure in the body before diving and perform various tasks in the deep sea
(3)And when you return from work, you also have to go through a process of lowering the pressure
(4)a picture of the pressure relief chamber and the diving bell from above
(5)After the divers finished working in the deep sea, the round thing under the diving bell painting
(6)They’re coming up to the surface at high pressure from the deep sea
(7)When the diving bell docks in the pressure-sensitive chamber at the same pressure, it moves to the pressure-sensitive chamber The space where D1 to D4 are located in the figure
(8)The diving bell and the decompression chamber are connected by a narrow passageway with doors on each side
(9)After the divers move to the decompression chamber, close the hatch to the decompression chamber to completely seal the space
(10)Slowly release the pressure from the diving bell and trunk, then release the clamp at the end to separate the diving bell
(11)Divers that are still at high atmospheric pressure after that are in an enclosed decompression chamber
(12)The department will proceed with the decompression procedure slowly
(13)The person in charge of this work is called a dive tender T1 and T2 in Figure

(1)However, on November 5, 1983, an error occurred in the decompression chamber of the drilling rig in the North Sea of Dolphin Norway, Byford
(2)Byford Dolphin’s Diving Bell
(3)William Cramond, who was a dive tender T1 T2, suddenly released the clamp of the dive bell while the hatch was not closed yet after the divers D1 to D4 arrived in the decompression chamber, and there is a possibility of an error due to overwork
(4)The result is that the high pressure diving bell and the decompression chamber are instantly exposed to low pressure
(5)Because of this dramatic pressure difference, the diving bell bounced off like an explosion
(6)William Crammond died instantly, Martin
(7)Saunders was seriously injured
(8)And the diver in the decompression chamber because the hatch was not closed
(9)The fields are also exposed to low pressure without any contrast

(1)Edwin Coward and Roy Lucas Bjorn Bergeson D1-D3 are instantly exposed to 1 atmosphere at 9 atmospheric pressure and suffer explosive decompression
(2)Most of the blood in their arteries and veins, such as their cardiovascular and cerebrovascular vessels, boiled and vaporized, and internal organs in the body degenerated butter
(3)They are presumed to have died instantly due to a rupture in the circulatory system while all the blood in the body was boiling in an instant
(4)And in the case of Trulx Hellevik D4
(5)Standing in front of it to close the hatch of the decompression chamber, an accident occurred, air escaping through the less closed gap of the hatch, and he was also swept away by this explosive flow of air
(6)He crumpled through these less closed doors and was pulled out and died in a terrible form, tearing his whole body into small pieces
(7)The body was so severely damaged that it was impossible to completely recover it, but when his body was sent to a university hospital for an autopsy, it was said to have arrived in four plastic bags divided into four
(8)A reproduction of the situation of Trulx Hellevic D4 at the time of the incident, and you can see the hatch slightly open
(9)He had a scalp with long blonde hair, but he didn’t have the top of his skull and the brain Soft tissue on the face was found, but completely detached from the bone His left arm fell off his body just below the shoulder joint, and his right arm shattered with attachment Right thigh, leg, foot missing, but knee joint found The left thigh was separated from the pelvis just below the hip joint, and the pelvis itself was divided into three parts All the organs in the chest and abdomen have been discharged except for the organs and parts of the small intestine Even his spinal cord fell off his body during the explosion and was found on the deck of the equipment 33 feet 10 meters above where the explosion occurred
(10)An autopsy report by Dr. Giertsen, a professor of forensic science at the University of Bergen
(11)Safety checks on undersea drilling rigs since this terrible accident in 1983
(12)It is said that the teeth have been strengthened and the accident rate has been greatly eased
The difference in air pressure at the time of the accident was eight to 9 atmospheric pressure
The air pressure difference in the Titan submarine accident is 400 atmospheric pressure difference
