India’s first wave-powered navigational buoy launched in Chennai

A wave-powered navigational buoy, developed by the National Institute of Ocean Technology (NIOT), to guide ships in and out of ports, was launched on 15 November 2017. The buoy, deployed at Ennore Kamarajar Port here, will help ships, moving in and out of the harbour, navigate through a designated channel.

According to the NIOT, the buoy’s beacon, for guiding ships, is powered by wave energy while conventional ones use solar power. The buoy stores energy generated by waves in a battery. Also, the buoy would be able to record data on wind speed and direction an various other aspects, which would be relayed to port authorities.

The buoy was launched by Secretary, Ministry of Earth Sciences M Rajeevan on the eve of the 33rd executive committee meet of International Energy Agency-Ocean Energy Systems Collaboration Programme (IEA-OES) and as part of a workshop ‘Harnessing Energy from the Oceans A global Scenario’. Head of Energy and Fresh Water, NIOT, Purnima Jalihal told reporters that the buoy, designed for a life span of about 15-20 years, is fully indigenous and it costs less than imported buoys. India would join working groups to partner with other countries in developing ocean energy technologies and this would help in testing indigenous prototypes in accordance to international requirements and norms
