According to the Navy, operations have been hindered as a large amount of muddy water has entered the vessel, blocking the view. Moreover, the submarine has melted in many parts due to the explosion, which makes it even more inaccessible. To add to the woes of the navy divers, none of them are skilled welders or cutters and are not trained for this kind of a rescue operation.
Nevertheless, the rescue work is still on, despite problems arising due to tidal changes too. The rescuers managed to enter the submarine from the top by cutting open a portion of it, only to find their entry blocked. They then tried to enter it from the tail, only to fail again. Subsequent efforts have been made to re-float the vessel, but the lack of ballast equipment proved to be an obstacle.
INS Sindhurakshak sunk with 18 crew members in the wee hours of Wednesday after an explosion and subsequent fire. Experts believe that the blast was triggered by torpedoes that got triggered due to Hydrogen gas leak from the battery chamber.
