What causes the oil spill at sea?

With the strengthening of marine development and the continuous development of marine transportation industry, oil spills have occurred continuously at sea in recent years, which has aroused great concern. The weight of oil spilled into the sea around the world every year is about 10million tons. The occurrence of oil spills at sea not only causes huge waste of resources and economic losses, but also directly destroys the marine environment. Therefore, it is urgent to study the causes of oil spill accidents and the corresponding treatment measures.Cause analysis of oil spill accident at sea.There are many reasons leading to oil spills at sea, such as the complex and changeable marine climate environment; Operators, managers and operators do not attach great importance to their ideology at work; Insufficient preparation in knowledge, technology, facilities and equipment, etc. However, the fundamental reasons are as follows:Oil developers and transporters are reckless for their interests. The temptation of huge profits makes many manufacturers all over the world regardless of high risks such as possible oil spills and oil spills, and blindly pursue the high returns brought by this industry. In order to meet the oil demand of domestic and foreign markets. On the one hand, oil developers and transporters constantly explore and develop new oil fields, and continuously transport oil to all parts of the world. The final result of this development is that many exploration, development, transportation, oil refining, pipelines and other equipment are overloaded for a long time, and soon become aging and seriously damaged. Oil spills and oil spills are imminent. A similar case occurred on August 6, 2006. Due to the aging and serious corrosion of its oil pipeline, the Prudhoe Bay oil field, 30 miles away from the Arctic reserve, eventually led to crude oil leakage, causing serious consequences. On the other hand, in order to reduce transportation costs and maximize their own interests, oil carriers often carry out oil transportation under extremely unsafe conditions, which poses a great threat to ship safety and the marine environment. For example, in 1991, the "abt summer" tanker loaded with nearly 260000 tons of heavy oil spilled 80million gallons in the waters of Angola, and the main reason for the oil spill of the ship was overloading
