National Institute Of Oceanography Develops Technology To Tackle Ballast Water

Marine ecosystem is always a difficult concept to digest given that we have a good amount of management to be done on land itself. Foreign elements are sometimes carried away and get mixed with marine water through cargo ships at some remote location. This leads to a problem called ballast water. It won’t be a problem anymore. Indian scientists at National institute of Oceanography (NIO)have now found out a new technology to treat this ballast water.

The water used to provide stability to a cargo ship in cases of foul weather and to improve its mobility is called Ballast water. It is many times noted that such water carries with it foreign particles, plankton sometimes radioactive particles and other harmful algae which when released multiply at a place where that cargo is unloaded. This contaminated water in ships is called as Ballast water. National Institute of Oceanography had collaborated with Mumbai University Institute of Chemical Technology and National Chemical Laboratory, Pune has developed a technology which can sterilize the water up to or below the standards prescribed by International Maritime Organization of United Nations.


The technology called The Ballast Water Treatment technology has been patented by NIO which is also supported by Ministry of Shipping. Presently four ports in India, two in Mumbai and other two in Goa and Vishakhapatnam have been identified by Ministry of shipping for implementing the ballast water treatment technology. It is expected that it would be implemented at 12 major ports till 2016.

The ministry of Shipping has also designed a program for implementation of this technology. The various steps to be undertaken during this program would be carrying biological baseline surveys on all selected ports, assessing the Ballast Water Risk, recording data by creating a Geographical information system for ballast water management identifying suitable location for discharge of ballast water in emergencies. The program would also focus on conducting ballast water sampling and developing an electronic reporting forum.

The project cost allocated Research and development was about Rs. 15 Crore. The technique thus developed is an eco friendly one. Earlier chemicals had to be added which was also a costly method and there was also a chance that it may prove more fatal than helpful. The program undertaken by the ministry and NIO is really a good one promoting eco friendly technologies in the preservation of oceanic environment.
