Strengthening Ocean Protection: Indian Coast Guard’s NATPOLREX-X Enhances Marine Pollution Response Efforts

The Indian Coast Guard (ICG) recently completed the 10th National Level Pollution Response Exercise (NATPOLREX-X) from October 5–6, 2025, off the coast of Chennai, Tamil Nadu. This exercise focuses on improving India’s ability to respond to oil spills, a key part of the country’s environmental protection efforts.

During this exercise, over 105 national delegates and 40 foreign observers from 32 countries participated, showcasing India’s growing role in maritime environmental safety.

The NATPOLREX series, organized by the Ministry of Defence, aims to enhance coordination among various agencies to tackle potential marine pollution. Since 1986, the ICG has been the main body overseeing oil spill responses. Director General Paramesh Sivamani highlighted the importance of teamwork and quick action in managing pollution.

He noted, “Marine pollution requires a united effort from multiple stakeholders. Exercises like NATPOLREX-X prepare us for quick and effective action to protect our waters.”

One standout feature of NATPOLREX-X was the first-ever shoreline clean-up drill at Marina Beach, Chennai. This initiative involved local agencies like the Greater Chennai Corporation and the Tamil Nadu Pollution Control Board. The drill simulated a major oil spill and showcased how local and national authorities can work together to manage pollution along the coast. This highlights the importance of local communities in the national response strategy.

During the exercise, ICG deployed advanced resources such as:

• Pollution Control Vessels (PCVs) for containment and recovery
• Offshore Patrol Vessels (OPVs) for quick response
• Chetak and Dornier aircraft for aerial surveillance and pollution assessment

These resources demonstrate a coordinated approach between sea, air, and land units.

The exercise also featured discussions on pressing issues in marine pollution management. Topics included:

• Nurdle spills and their environmental impact
• Hazardous and Noxious Substances (HNS)
• Post-spill assessments and clean-up strategies

These conversations helped experts share insights and improve decision-making for future responses.

Key participants included central and state ministries, major ports, and international maritime organizations. The 27th National Oil Spill Disaster Contingency Plan (NOSDCP) meeting, held simultaneously, reviewed national policies and improved communication among agencies.

This exercise reflects India’s move toward self-reliance in maritime technology. Many vessels and equipment used were produced in India, showing the success of the Make in India initiative.

India relies on sea routes for over 75% of its energy imports. Thus, having a strong oil spill response is crucial for energy security, marine conservation, and economic stability. The NOSDCP, established in 1993, underpins the country’s oil spill readiness and is supported by four Pollution Response Centres across key maritime zones.

NATPOLREX-X emphasizes India’s commitment to protecting the marine environment and maintaining its role in international agreements like the MARPOL Convention. It highlights the country’s focus on a sustainable Blue Economy, blending environmental care with economic growth.

As global attention on marine issues grows, India’s strong stance in pollution response positions it as a leader in the Indo-Pacific region.
