ABSTRACT Oil spills pose a serious danger to marine ecosystems both offshore and on land. Various methods exist for removing oil from the water, and this article will cover the basics of four of them: physical, chemical, thermal, and biological. Physical remediation, which does not harm marine life much, is one of the eco‐friendliest ways to clean up oil spills. The approach relies heavily on the ocean and its environs at the oil spill site, though. In marine ecosystems, the most cost‐effective and efficient way to mitigate the effects of oil spills is to use booms, skimmers, and natural sorbents. Thermal treatment can remove up to 98% of oil spills with very little specialized equipment. This method works well when there is no wind, no recent spills, and no very combustible items. The risk of air pollution and harm to marine life is real, though. Even though it is dangerous to the environment, chemical remediation is a quick and effective way to clear up an event. Dispersing, breaking emulsions, sinking, washing surfaces, solidifying, and inhibiting are some of the many chemical properties used. The most effective methods for dealing with oil spills at sea include bioremediation, dispersion application, and mechanical oil recovery. Plans for responding to an oil spill could yield different outcomes depending on factors such as the type of oil, the microbes in the area, and water properties (such as temperature and nutrient availability). Government policies have a significant impact on catastrophe management and repair operations. Existing cleanup technology, such as skimmers and booms, has its share of issues, and biological approaches are particularly susceptible to the worldwide variability in climate, water currents, and wind. Cleanup techniques that pollute land and water and injure marine life, such as in situ procedures and dispersants, have high environmental costs.
