Oil releases into the sea or coastal waterways are generally referred to as marine oil spills, however land-based spills are also possible.
Oil spills can result from crude oil discharges from tankers, sinking of oil tankers, offshore platforms, drilling rigs, and wells as well as refined petroleum products (like gasoline and diesel) and their byproducts, heavier fuels used by big ships like bunker fuel, or the spill of any oily waste or garbage.
