HUMANITARIAN EFFORTS BY NAVY AND AIR FORCE AT CHITRAKONDA 

Visakhapatnam – 05 Jul 08

 

Seven days have passed since tragedy struck at Chitrakonda. A large contingent of Naval divers have toiled from first light to nightfall on every day of the ensuing period, through difficult conditions in cold, muddy and crocodile-infested waters with poor underwater visibility, to extricate in tandem with the Police and Civil authorities, twenty four bodies from the sunken launch. Naval and Air Force helicopters have braved unfavourable weather providing casualty evacuation, search effort and logistic support.      

 

The first challenge, in the absence of any telltale signs, was to localise the search area, as combing reservoir would have taken an inordinate amount of time. A probable area was arrived at careful analysis witness accounts from the survivors, conduct of an aerial survey, and reconstruction of the sequence of events. While state of the art Side Scan Sonars, flown in from Naval ships allowed technology to peep under water, the hardy divers employed everything they knew, including searches using snag lines, grapnels and underwater ropeways.

Chitrakonda reservoir, unlike other water bodies, has a large number of big tree trunks lying on its bed. The reservoir bed itself is jagged, as the water body lies among hills, with depths varying randomly from 15 to 40 meters, with very steep gradients. These factors rendered unworkable the conventional method of ‘trawling’ the bottom dragging a weighted rope underwater. Another challenge was the muddy waters, which forced the divers to ‘find’ by ‘touch and feel’, thus limiting the area they could sweep at one time. This painstaking search was done by Naval divers inching along an underwater ropeway, groping in virtual darkness, lit only by a helmet-mounted light that penetrated barely a foot ahead.

The boat when finally located on 02 Jul 08, was resting its left side on a lake bed that descended steeply at an angle of almost 70 degrees, making the boat itself nearly vertical, with the front end embedded in slush. This position limited the access into the boat and also restricted the number of divers who could work simultaneously without getting entangled. Further, at a depth of 37 meters where the boat rested, the divers could work in spells of just 17 minutes, as exceeding this would jeopardise their lives.

For retrieving the bodies, the Naval divers, with air cylinders strapped to their backs, would crawl in through the windows that measured just two feet by two feet and carefully draw the bodies out and commence the ascent to the top. Technicalities of underwater diving necessitate the divers to stop at a middle depth for five minutes to allow their bodies to acclimatize to the changing pressures. These five minutes spent suspended in the dark between the bottom and the surface, holding on to a corpse, would arguably be the longest anyone could ever spend.

The task of recovering bodies had to be complemented with Naval and Air Force air effort, which would ferry the causalities and the bodies to Visakhapatnam mostly through challenging, marginal weather conditions that deteriorate without warning in the hills.

As the attempts to winch the boat up have not succeeded yet and are wrought with innate delays, diving has remained the only practical method of recovering the rest of the personnel. But as the sun rises on Day Seven of the tragedy, the hope of recovering all bodies has received a fillip with the door accessing the front portion of the boat having been found by nightfall on Friday. Vice Admiral Nirmal Verma, Flag Officer Commanding-in-Chief, Eastern Naval Command made a visit to the area today, 05 Jul 08 for a first hand appreciation of the operations underway. A quick retrieval of a large number of the occupants that are expected to be in this part of the boat can now be hoped for.

For the military man on the scene, tomorrow is yet another day, to be spent in selfless service to the nation, his training and discipline, the bulwarks of his performance.
