By: Dr PK KrishnakumarThe Arabian Sea off Kerala’s coast has become an unlikely graveyard for cargo giants, with two devastating maritime disasters sending shockwaves through the region’s delicate marine ecosystem.

The sinking of the Liberia-flagged MSC Elsa 3 carrying 640 containers including hazardous materials and over 450 metric tonnes of fuel, was followed by the explosive fire aboard Singapore-flagged MV Wan Hai 503, which carried 1,754 containers and 2,240 tonnes of fuel. These twin catastrophes have unleashed a cascade of environmental threats during Kerala’s critical monsoon breeding season, when marine life is most vulnerable.The timing couldn’t be worse. Kerala’s coast experiences one of the world’s most significant upwelling systems during the southwest monsoon, creating a marine nursery that sustains the region’s vital fishing industry. With spawning season in full swing, any contamination poses catastrophic risks to fish populations, coastal communities, and the broader marine food web. Already, plastic nurdles have begun washing ashore, offering a grim preview of the ecological devastation that may unfold.

The scale of these disasters demands immediate, coordinated action that goes far beyond traditional cleanup efforts. Emergency response teams must implement comprehensive mitigation strategies designed to contain the spread of pollutants while protecting Kerala’s marine treasures. The first critical step involves deploying advanced hydrodynamic modelling systems to predict the movement of floating containers, oil slicks, and chemical dispersants across the Arabian Sea’s complex current patterns.Biomonitoring programmes must be established as environmental watchdogs, tracking contamination levels in seawater, sediments, and marine organisms across multiple sampling stations. These programmes can focus particularly on pollution ‘hot spots’ around the wreck sites and vulnerable shoreline areas where contamination is most likely to concentrate. Scientists need to collect samples from everything from microscopic plankton to commercially important fish species, creating a comprehensive picture of the disaster’s environmental footprint.The response strategy also emphasizes protecting sensitive marine ecosystems through targeted interventions. Specialized teams have to work to identify and safeguard coral reefs and other critical habitats within the impact zone. Meanwhile, contingency plans need to be activated to address the most pressing public health concerns: Determining whether seafood from affected areas remains safe for consumption and establishing clear guidelines for fishing moratoriums.Perhaps most importantly, authorities must develop long-term maritime disaster management frameworks that integrate marine scientists, fishery experts, and shipping specialists into state-level emergency response teams. This multidisciplinary approach will ensure that future incidents can be addressed with the full spectrum of technical expertise required for effective containment and recovery.The legal framework governing maritime disasters operates through a complex web of international conventions, national laws, and insurance mechanisms that can seem as treacherous as the sea itself.

Under international maritime law, shipowners bear primary responsibility for pollution damage caused by their vessels, a principle that places the burden of compensation squarely on the companies operating these cargo giants.The foundation of this system rests on several key international conventions. For oil spills, the Civil Liability Convention establishes strict liability standards for shipowners, while the International Oil Pollution Compensation Fund provides additional coverage when damages exceed the shipowner’s insurance limits.

For hazardous substances beyond oil, the Hazardous and Noxious Substances (HNS) Convention creates a parallel compensation framework, though its global implementation remains incomplete.The legal obligations extend beyond simple financial liability. Shipowners are required by law to maintain comprehensive insurance coverage through Protection and Indemnity Clubs, specialized marine insurers that cover pollution damage.

This mandatory insurance system ensures that funds are available for immediate response efforts, even as longer-term compensation claims work their way through the legal system.Securing compensation for maritime environmental disasters follows a structured process that transforms ecological damage into quantifiable financial claims. The journey begins with immediate notification to relevant authorities, including coast guards and maritime agencies, establishing the official record of the incident and triggering the compensation framework.The most critical phase involves comprehensive damage assessment, where teams of experts document every aspect of the environmental and economic impact. This includes obvious costs like cleanup operations and property damage, but extends to more complex calculations of economic losses in fisheries and tourism, environmental restoration expenses, and the intricate process of valuing ecosystem services that may be compromised for years.Claims must be meticulously documented with detailed invoices, scientific evidence of damage, and clear proof linking the harm to the specific maritime incident. The Sri Lankan govt’s experience with the X-Press Pearl disaster provides a telling example: Initial claims of $40 million eventually expanded to $6.4 billion as the full scope of environmental damage became clear.The compensation process typically begins with direct claims to shipowners or their insurers, with additional funds available through international compensation funds when insurance coverage proves insufficient. If disputes arise, the matter can proceed to national courts or international arbitration, depending on the specific circumstances and jurisdictions involved.As cleanup efforts continue and legal proceedings unfold, these twin catastrophes will likely reshape how India approaches maritime safety and environmental protection in its coastal waters.The writer is former principal scientist, CMFRI Mangalore Centre & senior consultant, National Center for Wildlife, Saudi Arabia
