Chennai Port - Natural Disasters

Natural Disasters

The Indian Ocean Tsunami of 26 December 2004, one of the deadliest in the recorded history, had a devastating effect all over the region and, of course, damaged the port's infrastructure, including cranes, wharfs, moorings and some part of the ship channel and hindered the operations of the port for a brief period. Some of the ships hit the wharves close to where they were berthed. Other damages at the port include collision of three ships while being towed to deep sea resulting in the loss of about 1,500 tonnes of sugar and damages to some of the cars that awaited export. The port suspended operations for two days. The total damage to property, infrastructure and equipment at the port due to the tsunami stood at 129.6 million. Rebuilding the entry channels and affected areas incurred another 100 million. The port suffered a loss of 30 million due to operational halt on 26 and 27 December 2004, during which around 250,000 tonnes of container could not be serviced, with trade of 15 vessels on sail and 10 vessels at berth affected. This was in addition to the loss due to waiving of marine charges owing to the disaster.

As a consequence of the tsunami, the port trust is planning to create an artificial beach from left of the Cooum river (next to the Napier bridge) right up to fishing harbour in North Chennai covering about 10 km to protect the port from seaside from similar natural calamities. The beach is planned within the port's territory before the east breakwater on the seaside and would not be accessible to the public. In addition, the port is also planning to reclaim the land adjacent to the Cooum during the Tenth Plan.

On the flip side, the disaster has made the port the deepest on the east coast. A bathymetry survey conducted by the National Institute of Ocean Technology (NIOT) to measure the depth of the sea has revealed the entry channel to the port has deepened enabling the berthing of vessels of deeper drafts. The high current generated by the tsunami waves dredged about 0.4 to 0.5 million cubic metres of sediments, which has deepened the 17.4 m-deep harbour by 1 to 2 m more, especially along the Dr. Ambedkar Dock and the Barathi Dock. Similarly, the depth of the entry channel, which was 18.6 m, has deepened by a metre.
