Sarbananda Sonowal launches ‘SAGAR SAMRIDDHI’


The Union Minister of Ports, Shipping and Waterways, Sarbananda Sonowal, launched the ‘Sagar Samriddhi’ online dredging monitoring system as part of the ‘Waste to Wealth’ initiative of the ministry. The National Technology Centre for Ports, Waterways and Coasts (NTCPWC) developed the system, which replaces the old Draft and Loading Monitor system and offers improved efficiency and transparency.

  • The Ministry of Ports, Shipping and Waterways also updated its ‘Dredging Guidelines for Major Ports’ to outline the planning and preparation, technical investigations, dredged material management, and cost estimation procedures for dredging projects, including enabling the ports to formulate and complete them within specified timelines.
  • The ministry issued an addendum in March 2023 for the disposal of dredged material, which would reduce the cost of dredging, and the online system would facilitate cost reduction along with increased efficiency and transparency.


The ministry aims to develop major ports into trans-shipment hubs with deep drafts of over 18 meters as part of its Maritime India Vision 2030.
