Navy divers set national record for deep diving

Sify - 

Five Indian Navy Divers on board INS Nireekshak of Southern Naval Command have set a new national record for deep diving earlier this month. 

Lieutenant Commander Abhijeet Sangle, Chief Petty Officer KK Singh, Chief Petty Officer Shriom Singh, Leading Seaman MK Prusty, and Leading Seaman Narender Kumar dived to a depth of 233 metres in the seas off Kochi, breaking an earlier record set by Indian Navy divers.

Such deep dives called saturation diving in professional circles, involve complex support systems from the Diving Support Vessel (INS Nireekshak) to enable the divers to explore the final frontiers in physical and mental endurance.

Water pressure increases by 1 kg/cm2 every 10 meters as the depth increases. Other complications of deep dives include physiological problems of bubbles formed by gas throughout the body causing "decompression sickness" as the divers come up to surface.

The complex science of saturation diving circumvented these problems with the aid of devices like decompression chambers.
