Polymetallic Sulphides

India has signed a 15-year contract to explore polymetallic sulphides (PMS) with ISA in Carlsberg Ridge in Indian Ocean.

  • It is India’s third exploration contract with International Seabed Authority (ISA), and second for PMS.
  • Previous exploration contracts are Polymetallic Nodules in the Central Indian Ocean Basin and PMS in the Indian Ocean Ridge.
    • Polymetallic nodules, also called manganese nodules, are rock concretions formed of concentric layers of iron and manganese hydroxides around a core, such as a shark tooth or shell.
  • This is the first licence granted globally for exploring polymetallic sulphur nodules in the Carlsberg Ridge.
  • The Carlsberg Ridge is a 3,00,000 sq km area in the Indian Ocean, specifically in the Arabian Sea, northwest Indian Ocean.
    • It forms the boundary between the Indian and Arabian tectonic plates, extending from near Rodrigues Island to the Owen fracture zone.
  • Previously, India has also applied for the Afanasy-Nikitin Sea (ANS) mount which is yet to be approved.
    • ANS is located in the Central Indian Ocean and the territory has been claimed by Sri Lanka for exploration rights.

About Polymetallic sulphides (PMS)

  • These deposits are rich sources of metals such as copper, zinc, gold, and silver, found on the ocean floor. 
  • These deposits occur in regions where hot, mineral-rich fluids from the Earth's mantle mixed with cold Ocean waters, leading to the precipitation of metal sulphides.

Ministry of Finance Gives infrastructure status to Large Ships

Key Initiatives for the Shipping Sector Bharat Container Shipping Line: A new container shipping line will be established under the Shipping Corporation of India.  Coastal Green Shipping Corridor: This initiative focuses on developing an environmentally friendly shipping route, with the Kandla–Tuticorin corridor planned as the first phase.  Sagarmala Startup & Innovation Initiative (S2I2): This program is designed to foster innovation in the maritime industry through the creation of Maritime Innovation Hubs.

Large ships are now included in ‘Transport and Logistics’ category of the Infrastructure Harmonized Master List (HML) of Infrastructure Sector, aimed to strengthen domestic shipbuilding and maritime industry.

  • A large ship is defined as Commercial Vessel: 
    • Having a gross tonnage (GT) of 10,000 or more, under the Indian ownership and flag; or
    • Having a GT of 1,500 or more which are built in India and are under Indian ownership and flag.
  • Significance of inclusion in HML: Access to infrastructure lending at easier terms with enhanced limits, access to larger amounts of funds as external commercial borrowings (ECB), viability gap funding, tax incentives etc.

Status of India’s Shipping Sector

  • Foreign Dependence: 95% of India’s trade relies on foreign ships and India pays nearly $75 billion every year to foreign shipping companies for shipping services. 
  • Share in Shipbuilding: India currently accounts for only 0.06% of global shipbuilding
  • Target: Government is aiming at becoming one of the top five shipbuilding nations by 2047 and according to Maritime Amrit Kaal Vision 2047, government foresees an investment of ₹54 trillion into building indigenous shipping and shipbuilding capabilities by 2047. 
  • Issues in Shipping Sector: Capital constraints with high borrowing costs, ageing fleet, tax anomalies, skill gaps etc.
