New Delhi: On May 26, 2025, the southern Indian state of Kerala declared a state of emergency following the capsizing of the Liberian-flagged cargo ship MSC Elsa 3, which sank 38 km southwest of Kochi in the Arabian Sea. The incident has raised significant concerns about a potential ecological disaster due to an oil spill and the presence of hazardous materials, including calcium carbide, aboard the vessel.
The Incident: MSC Elsa 3 Capsizes Off Kerala Coast
The MSC Elsa 3, a Liberian-flagged cargo ship, was en route from Vizhinjam port to Kochi when it encountered severe weather conditions early on Sunday, May 25, 2025. Reports indicate that a combination of heavy seas, possible hull leakage, mechanical failure, and potentially unbalanced cargo caused the vessel to develop a severe 26-degree starboard list, a maritime term for a dangerous tilt. Despite efforts to stabilize the ship, flooding in one of its compartments led to its capsizing and eventual sinking in the Arabian Sea.
The ship was carrying 640 cargo containers, including 13 containers with hazardous incendiary materials and 12 containing calcium carbide, a chemical that reacts violently with seawater to produce highly flammable acetylene gas. Additionally, the vessel had 84.44 metric tonnes of diesel and 367.1 metric tonnes of furnace oil in its tanks, heightening fears of a significant oil spill. The Indian National Centre for Ocean Information Services (INCOIS) has warned that more containers could drift toward the coasts of Thiruvananthapuram, Kollam, and Alappuzha within 48 hours, posing further risks to maritime traffic, fishing vessels, and coastal ecosystems.
Immediate Response: Crew Rescue and Coastal Alert
The Indian Coast Guard and Navy acted swiftly, rescuing all 24 crew members aboard the MSC Elsa 3. The crew, comprising one Russian, 20 Filipinos, two Ukrainians, and one Georgian, was safely evacuated after an hours-long operation. Following the rescue, the state government issued a high alert across Kerala’s coastal belt, urging residents to avoid the shore and refrain from touching any foreign objects, including containers or oil slicks, that might wash ashore.
On Monday, May 26, 2025, at least eight containers from the sunken vessel washed up on beaches in Kollam district, specifically at Neendakara, Karunagapally, and Shakthikulangara. Local police and revenue authorities cordoned off these areas, advising the public to maintain a minimum distance of 200 meters from the beached containers due to the risk of hazardous and flammable materials leaking. Sekhar Kuriakose, member secretary of the Kerala State Disaster Management Authority, emphasized the need for caution, given the potential for chemical leaks to endanger both residents and the environment.
Environmental Concerns: Oil Spill and Calcium Carbide Risks
The capsizing of the MSC Elsa 3 has raised alarms about a potential ecological disaster along Kerala’s biodiverse coastline, a critical tourist destination and home to rich marine ecosystems. An oil spill, defined as the release of liquid petroleum hydrocarbons into the environment due to human activity, poses severe threats to marine life and coastal economies. The spill from the MSC Elsa 3, involving diesel and furnace oil, could poison algae, disrupt food chains, and reduce yields of edible crustaceans such as clams and mussels. Fish hatcheries are at risk, with commercially valuable fish species facing contamination of their flesh. Fish larvae and free-swimming organisms are particularly vulnerable, while tar particles from the spill could smother benthic organisms living on the ocean floor.
The presence of calcium carbide aboard the ship exacerbates these concerns. This hazardous chemical reacts with seawater to produce acetylene gas, which is highly flammable and could ignite, posing risks to both the environment and human safety. The Indian Coast Guard has highlighted the potential for an ecological disaster if these materials are not contained promptly.
Pollution Control Measures: Technology and Deployment
To mitigate the environmental impact, the Indian Coast Guard has deployed advanced pollution control measures. An ICG ship, Saksham, equipped with specialized pollution response equipment, is stationed at the site of the capsizing. Additionally, an ICG aircraft fitted with an advanced oil spill detection system is conducting aerial surveillance to monitor the spread of the oil slick and floating containers. These efforts aim to contain the spill and prevent further damage to Kerala’s coastal ecosystems.
Several key technologies are being employed to address oil spills:
- Bioremediation: Technologies like Oilzapper and Oilivorous-S, developed by The Energy and Resources Institute (TERI), use bacteria to convert harmful hydrocarbons into harmless carbon dioxide and water. This eco-friendly approach is critical for breaking down oil in sensitive marine environments.
- Sorbents: Materials such as the fiber of the milkweed plant, commonly found in Rajasthan, are used to absorb oil from the water surface, aiding in containment and cleanup.
- Oil Booms: Large floating booms with skirts extending into the water are deployed to physically isolate the spill area, preventing the oil from spreading further.
- Skimmers: These machines concentrate and scrape oil from the water surface, enabling efficient removal of spilled oil.
These technologies, combined with the Coast Guard’s rapid response, are critical to minimizing the environmental fallout from the MSC Elsa 3 incident.
Regulatory Framework: Governing Oil Spills in India
India has a robust regulatory framework to address marine oil pollution, which is being applied to manage the current crisis:
- MARPOL (1973): The International Convention for the Prevention of Pollution from Ships includes comprehensive annexes specifically addressing oil pollution prevention and control, setting global standards for maritime environmental protection.
- BUNKER Convention (2001): This convention holds shipowners liable for bunker oil pollution, ensures comprehensive victim compensation, and mandates compulsory insurance coverage to address damages.
- Merchant Shipping Act (1958): This Indian legislation regulates shipping and incorporates MARPOL conventions, providing a legal basis for pollution control and maritime governance.
- National Oil Spill Disaster Contingency Plan (1996): Coordinated by the Indian Coast Guard, this plan outlines the response strategy for oil spills in India’s maritime zones, designating the Coast Guard as the nodal agency for spill response.
These frameworks ensure a coordinated and legally supported response to the MSC Elsa 3 incident, with the Indian Coast Guard playing a central role in containment and cleanup efforts.
Societal Impact: Evacuations and Public Safety Measures
The capsizing has prompted significant public safety measures along Kerala’s coast. Authorities have evacuated areas near the beached containers and issued warnings to fishermen to avoid venturing too close to the sunken ship, where floating containers pose a collision risk. The chief minister’s office has sounded an alert across the coastal belt, emphasizing that the oil slick could reach anywhere along Kerala’s shores, necessitating widespread vigilance.
The containers washing ashore in Kollam have sparked fears of chemical leaks, with local police reporting at least four containers spotted along the southern Kollam coast, though the total number remains unconfirmed. The Customs department has verified the ship’s cargo manifesto, confirming the presence of hazardous materials, which has heightened the urgency of the response.
Broader Implications: Tourism and Fisheries at Risk
Kerala’s coastal stretch, known for its biodiversity and tourism appeal, faces significant risks from the oil spill and potential chemical leaks. The contamination of marine ecosystems could devastate local fisheries, which are a vital source of livelihood for coastal communities. Commercially valuable fish species, already threatened by contamination, could see reduced yields, impacting both local economies and food security. Additionally, the tourism industry, which relies on Kerala’s pristine beaches and backwaters, could suffer if the oil slick and hazardous materials damage the region’s natural beauty.
Ongoing Monitoring and Future Outlook
The Indian Coast Guard and Navy remain on high alert, with ongoing surveillance and containment efforts. INCOIS has warned that more containers are likely to drift toward Alappuzha and Thiruvananthapuram in the coming days, necessitating continued vigilance. The state government, in coordination with national agencies, is working to prevent further environmental damage and protect public health.
As the situation evolves, authorities are intensifying pollution control measures and urging the public to cooperate by avoiding coastal areas and reporting any suspicious objects. The coordinated response, backed by advanced technology and a robust regulatory framework, aims to mitigate the immediate risks and prevent a long-term ecological disaster.
