About 71% of of the earth’s surface is covered with water and in that cover oceans hold about 96.5% of the total water cover and keeping that in mind, the health of the oceans plays a vital role in the overall impact on climate.

This was the general observation by the experts at the inaugural session of the three-day second World Ocean Science Congress (WOCS) that began here at Andhra University on Monday.

All the experts were of the opinion that it was time for all stakeholders to come together to a common consensus to stop the degradation of the oceans and work towards a better future, as oceans have a direct role in climate change.

Union Minister Suresh Prabhu addressed the gathering through video conference.

Speaking on the occasion at the inaugural session, Chairman and Managing Director of Hindustan Shipyard Limited Rear Admiral L.V. Sarat Babu said ship building and shipping is one among the stakeholders and has an important role to play.

According to him, discharge of ballast water from ships is a major issue, as discharging of untreated water leads to transfer of invasive microorganisms from one region to another.

Sulphur emission

“International Maritime Organisation (IMO) has already passed a resolution that all ships should have a treatment plant to treat the ballast water using various technologies such as heating, ultraviolet or membrane, before discharging,” he said.

According to him, capping on sulphur emission by ships is another area that needs to be looked into. “The present norm is 3.5% and IMO has already passed a resolution that it should be reduced to 0.5% by October this year. About 70,000 transoceanic ships will have to change to new low-emission fuel or install scrubbers. Shipyards also have think of new methods of discharging their waste,” he said.

Flag-officer-Commanding-in-Chief of Eastern Naval Command, Vice- Admiral Karambir Singh, in his address, pointed out that India has a rich maritime history and the focus should now be on modernising the fishing fleet, modern technology to explore seabed resources, enhance the efficiency of ports, new and green technology for seabed mining and bring out a common agenda for national maritime conservation.
