Kerala Oil Spill Incident

Source:  NIE

Context: A Liberian-flagged cargo vessel MSC ELSA 3, carrying hazardous material, capsized 38 nautical miles off Kochi, raising concerns of a major oil spill.

About Kerala Oil Spill Incident:

• MSC ELSA 3 sank due to flooding in one of its holds while en route from Vizhinjam to Kochi.
• The vessel was carrying 640 containers, including 13 hazardous cargoes, 84.44 MT diesel, and 367.1 MT furnace oil.

• Hazards onboard: Calcium carbide, hazardous chemicals, and large fuel volumes.

About Oil Spills:

• What is an Oil Spill?
  • An accidental release of petroleum or related substances into oceans, seas, or coastal waters.
  • Forms a toxic film that blocks sunlight, affects marine oxygen levels, and harms aquatic life.
• Impacts of Oil Spills:
  • Marine Life Destruction:
    • Coating of birds, mammals, and turtles disrupts thermoregulation and mobility.
    • Toxic exposure affects fish reproduction, growth, and survival.
  • Ecosystem Disruption:
    • Destroys phytoplankton, mangroves, coral reefs, and marine food chains.
    • Long-lasting contamination in coastal areas and estuaries.
  • Economic Losses:
    • Hits fisheries, tourism, and shipping industries.
    • Cleanup and compensation costs are extremely high.
  • Legal Framework Governing Oil Spills:
    • International Conventions:
      • MARPOL (1973/78): Marine Pollution prevention by IMO; India is a signatory.
      • OPRC Convention (1990): Facilitates global cooperation in oil spill response.
    • Indian Laws:
      • Merchant Shipping Act, 1958: Governs pollution control in Indian waters.
      • National Oil Spill Disaster Contingency Plan (NOS-DCP):
        • Managed by Indian Coast Guard as the nodal response agency.
        • Ensures monitoring, emergency response, and public safety.
      • Technologies & Methods to Manage Oil Spills:
        • Skimmers: Devices that physically remove oil from the water surface.
        • Dispersants: Chemicals that break oil into small droplets for microbial degradation.
        • Oil Booms: Floating barriers used to contain oil spread.
        • In-situ Burning: Controlled burning of surface oil in isolated patches.
        • Bioremediation: Use of oil-eating microbes, e.g., TERI’s Oil Zapper.
