Mongla Port was designed for berthing ships having 8.50 m draft. Upto 1980 there was not any siltation problem either in Jetty front or Channel area. But after 1980 siltation started in Jetty front Area. From that time regular maintenance dredging was performed in jetty front area. In the meantime it was seen that siltation has started in Harbour Area (About 13 Km downstream from Port Jetty). Due to this siltation, 03 times capital dredging project has implemented in the year of 1994 - 1995, 2004 - 2005 & 2013-2014. Another Capital Dredging at Mongla Port to Rampal Power Plant has implemented in 2017-2019. For regular maintenance dredging, Mongla Port Authority have 02 nos 18” dia Cutter Suction Dredger.

Ongoing Dredging: 

  • To bring 9.5/10 m draft vessel upto Harbaria Anchorage of Mongla Port, presently dredging at Outer Bar (Mouth of Pussur River) is ongoing. Total 10.4 Million cu.m and 11 km will be dredged by 2020. 
  • Another project to dredge at the inner bar i.e Harbaria to Port Jetty will start from January 2021. Total 23.4 km and 21.06 Million cu.m will be dredged by 2022. After completion of this project, minimum 9.5 meter draft vessel will be able to berth at Jetty.
  • Regular Maintenance dredging at Berth/ Jetty area is also ongoing through MPA's Dredger.

Under Preparation Process: To maintain the channel depth minimum 8.5 m, long term maintenance dredging project is under preparation process.
