Environmental Disaster in the Kerch Strait: December 2024 Fuel Oil Spill
On December 15, 2024, the Kerch Strait, Crimea, Black See, witnessed one of the most significant environmental disasters in the region’s history. Two Russian tankers of the “Volgoneft” class — “Volgoneft-212” and “Volgoneft-239” — sustained critical hull damage during a severe storm, leading to a massive spill of fuel oil. One crew member tragically lost his life, and the aquatic and coastal ecosystems suffered extensive damage.
Causes and Scale of the Disaster
The tankers, designed primarily for transporting petroleum products through inland waterways, ventured into open sea conditions beyond their technical capabilities. Their age, exceeding 50 years, further increased the risks. Moreover, an investigation by Rostransnadzor (The Federal Service for Supervision of Transport of Russian Federation) revealed that the vessels were operating in violation of seasonal restrictions, and the transportation of hazardous cargo was conducted without proper licensing.
Experts estimate that approximately 3,000 tons of M100-grade fuel oil were spilled. This type of fuel oil is highly dense and does not float on water like other petroleum products. Instead, it sinks to the seabed or remains suspended in the water column, making cleanup efforts significantly more challenging.
Environmental Impact
The spill caused extensive damage to the region’s natural environment, contaminating an area estimated at 30,000–40,000 square kilometers. Marine mammals and birds were the most severely affected. As of early January 2025, reports confirmed the deaths of over 32 dolphins and tens of thousands of birds. In the Anapa and Temryuk districts alone, volunteers rescued over 4,800 birds, but a large number of them succumbed due to insufficient rehabilitation.
Volunteers working to clean the coastline faced numerous challenges. The absence of specialized equipment made it difficult to remove fuel oil from pebble beaches, while exposure to toxic substances caused health issues, including poisoning and respiratory irritation.
Specifics of M100 Fuel Oil
M100 fuel oil is a heavy petroleum product composed of hydrocarbons, resins, asphaltenes, and other organic compounds. It is characterized by high viscosity, a freezing point of up to 40°C, and significant sulfur content. A single ton of this oil can create a slick covering up to 12 square kilometers.
Due to its density, cleanup efforts primarily focus on collecting the oil from shorelines after it washes up. However, even after visible cleanup, residual oil continues to pollute the marine environment, slowly breaking down and entering food chains, causing long-term harm.
Impact on Flora and Fauna
The disaster led to mass mortality among marine life, including at least 32 dolphins and thousands of birds. Waterfowl were particularly affected as their feathers lost their natural water-repellent coating due to the oil, leaving them unable to stay afloat or retain heat. Experts estimate that between 15,000 and 20,000 birds may have perished.
Oil that settled on the seabed disrupted marine habitats, reducing the food supply for fish and birds. Environmentalists predict that the full recovery of the region’s ecosystem could take over a decade, as residual oil slowly degrades or enters the food chain, continuing to harm living organisms.
Challenges in Response Efforts
Efforts to mitigate the disaster are hindered by a lack of specialized equipment, particularly for rocky beaches, and the health risks faced by volunteers exposed to toxic substances. Many reported respiratory problems and skin irritation.
The issue of rehabilitating affected birds remains acute. Volunteers worked to clean and care for them, but many were released prematurely due to pressure from officials, leading to mass fatalities. The weakened birds could not survive in the wild.
Prospects for Recovery
Experts predict that restoring the region’s ecosystem will take at least ten years. While some petroleum products will gradually break down, others will persist, contaminating food chains and causing long-lasting ecological damage.
Investigations revealed that the tankers were operating in violation of seasonal restrictions. Furthermore, several vessels owned by the “Volgotransneft” company lacked licenses to transport hazardous cargo. Negligence on the part of shipowners and inadequate oversight by regulatory authorities were identified as major contributors to the disaster.
Conclusions
This disaster highlights the urgent need for stricter regulations on hazardous cargo transportation, improved emergency response protocols, and the adoption of modern technologies for cleaning marine environments. Only coordinated efforts by authorities, environmentalists, and volunteers can mitigate the devastating effects of such incidents in the future.
The Kerch Strait fuel oil spill serves as a sobering reminder of the importance of stringent maritime safety measures and the implementation of advanced ecological restoration technologies. Its impact on the region’s biodiversity will be felt for decades to come.
