/ About Us / ABOUT NIOT




The National Institute of Ocean Technology (NIOT) was established in November 1993 as an autonomous society under the Ministry of Earth Sciences, Government of India. NIOT is managed by a Governing Council and the Director is the head of the Institute. Major aim of starting NIOT under the Ministry of Earth Sciences, is to develop reliable indigenous technologies to solve the various engineering problems associated with harvesting of non-living and living resources in the Indian Exclusive Economic Zone (EEZ), which is about two-thirds of the land area of India.



  • To develop world class technologies and their applications for sustainable utilization of ocean resources.
  • To provide competitive, value added technical services and solutions to organizations working in the oceans.
  • To develop a knowledge base and institutional capabilities in India for management of ocean resources and environment.



  • To develop technologies related to harnessing of ocean renewable energies namely wave energy, hydrokinetic energy and ocean thermal energy conversion (OTEC) and generating fresh water from seawater.
  • To develop technologies for offshore structural components and establish desalination plants in the Islands of Union Territory Lakshadweep.
  • To develop technology along with capacity building for the exploration and exploitation of deep ocean mineral resources such as poly-metallic manganese nodules and hydro-thermal sulphides occurring at Central and Southern Indian Ocean and gas hydrates within Exclusive Economic Zone.
  • To develop acoustic systems for ocean applications such as ambient noise measurements, acoustical oceanography, underwater communication and coastal surveillance.
  • To design and develop indigenous underwater acoustic imaging systems and allied technologies and to design and develop wide band underwater acoustic transducers and hydrophone arrays.
  • To design, develop and demonstrate new autonomous ocean observation technologies and systems for oceanographic applications.
  • To develop marine algal biotechnology, marine microbial biotechnology, open sea cage culture and ballast water treatment technologies.
  • To develop environmentally sustainable solutions for beach restoration and shoreline management by integrating state-of-the-art field measurements, numerical modeling studies and comprehensive detailed engineering designs.
  • To maintain the moored ocean observation network consisting of met-ocean and tsunami buoys for real time data transmission and to support RAMA program under the Indo-US collaboration and to disseminate data to INCOIS. To develop ocean observational tools prototype technology development.
  • To conduct operational management and maintenance of research ships and on board scientific equipment.
  • To develop and maintain a state of the art seafront research facility to enable activities in development and testing of prototype systems, validation of indigenously developed marine systems in the ocean environment.
