Plans Underway to Dredge Hooghly Estuary
Kolkata Port Trust is preparing to carry out maintenance dredging in Hooghly Estuary in the shipping channel of the port leading to Haldia as well as Kolkata, primarily at Jellingham & Auckland.
The plan calls for the use of trailing suction hopper dredgers in combination with bottom opening hopper barges.
The materials dredged by the dredger from Jellingham and Auckland will be loaded in the bottom opening barges, transported and dumped freely in the vicinity of Lower Sagar Dumping Area.
The present navigable depths are 4.1m at Jellingham and 4.6m at Auckland which are required be increased by 0.2m in the first year and further 0.1m in the 2nd year of the project.
