Marine oil spill accidents seriously damage coastal ecology, aquaculture resources and marine living environments. Oil pollution mainly comes from three mainstream scenarios: offshore crude oil platform leakage, cargo tanker collision & hull rupture, and illegal waste oil discharge from coastal factories and small vessels.
Once an oil spill occurs on the water surface, emergency response teams usually adopt physical interception first: deploy containment booms to enclose floating oil and prevent pollution from spreading to shore wetlands and breeding areas. After interception, skimmers are used to collect most floating crude oil on the water. For thin oil layers that cannot be physically recycled, food-grade biodegradable dispersants will be reasonably applied to accelerate oil decomposition under natural seawater oxidation.
Long-term prevention is more critical than emergency treatment. Strict port inspection of ship ballast water and waste oil storage, regular maintenance of undersea oil pipelines, and standardized supervision of coastal chemical enterprises can effectively cut down the probability of unexpected oil spills.
