Navy retrieves Rs. 30 Mn ADCP instrument beneath Hanwella bridge

A salvage mission conducted by the Navy divers on Tuesday (4) led to the recovery of an Acoustic Doppler Current Profiler (ADCP) instrument from beneath Hanwella bridge. Amidst torrential rainfall, this valuable device worth Rs. 30 million, owned by the Irrigation Department, was carried away by the surging waters of the Kelani River. The device ultimately became entangled in dense bamboo sticks and river debris.

The ADCP, also known as ‘River Ray,’ is used to measure the speed and direction of currents throughout the water column. With surging waters, its GPS device became entangled in bamboo bushes and debris carried by the water, causing it to detach from the main unit. It is in this backdrop, the Irrigation Department has requested assistance from Navy Headquarters, seeking Navy diving support to locate and retrieve the lost GPS device.

The Navy dispatched a team from Western Command Clearance Diving and Salvage Unit to the Hanwella area on Tuesday (4). Despite the perilous conditions caused by the Kelani River overflowing due to heavy rainfall, the Navy diving team retrieved the GPS device, which was entangled in underwater debris.
