Divers emerge after trip 300 meters under sea
Print Edition
SIX divers yesterday emerged safe and well from a living chamber that had taken them more than 300 meters under the sea, marking the success of China’s first 300-meter saturation dive experiment.
After remaining in the chamber for 380 hours, Hu Jian, Guan Meng, Dong Meng, Tan Hui, Luo Xiaoming and Li Hongjian came out around 9am, all in good health.
“This puts a successful conclusion to China’s first 300-meter saturation dive,” said Shen Hao, head of the Shanghai Salvage Company under the Ministry of Transport, which was responsible for the project.
On January 9, the six divers went into the living chamber, which was pressurized to the level 300 meters undersea.
The chamber took them 300 meters deep on January 12 and then witnessed them diving to as deep as 313.5 meters, said Shen.
Saturation diving technology enables human beings to withstand high water pressure by saturating human tissue with inert gas. This will allow divers to stay underwater for a longer time and at a deeper sea level than with conventional techniques.
It is used in deep-sea exploration, in rescue operations at sea and in engineering construction at the bottom of the sea.
China is researching technology that would work at 500 meters down, Shen said.
