[0002] An oil boom is an offshore oil spill emergency device that can effectively control oil spill accidents and recover spilled oil at sea. During the process of the oil boom releasing the oil containment, the oil containment bag is inflated and its own weight is used to achieve an upright balance state on the sea surface to achieve the effect of oil containment. After the oil boom is used and recovered, the oil containment bag is rolled up and stored back by deflating and rotating the roller.
