    The ocean is the origin of life. There are more than 200,000 species of creatures in the ocean, including about 180,000 species of animals and more than 20,000 species of plants. There are 25,000 species of fish in animals and more than 200 species of fish for human consumption. The ocean can provide human beings with green energy. The potential of ocean energy resources is quite large, including tidal energy, wave energy, temperature difference energy, salt difference energy, ocean current energy, tidal current energy, etc. According to estimates by American scholars, the theoretical reserves of ocean energy in the world are more than 1500×108kW, and 73.8×108kW can be developed and utilized, including 27×108kW of wave energy, 20×108kW of temperature difference energy, 26×108kW of salt difference energy, and 26×108kW of ocean current energy. 0.5×108kW, tidal energy 0.3×108kW. The ocean is an important channel for water transportation. Although international ocean cargo transportation has the shortcomings of low speed and high risk, it has become the main mode of transportation in international trade due to its large capacity, large volume, low freight, and strong adaptability to goods. 80% to 90% of my country’s total import and export cargo transportation is carried out by ocean transportation. The ocean has brought so many benefits to our life and production, and more and more large-scale development of the ocean has also caused harm to the ocean. On the other hand, it has always been seen as a bottomless pit for dumping waste, while at the same time relying on its inexhaustible source of rainwater. In fact, the ocean itself is very fragile, and its self-purification ability is limited. Recently, there are more and more signs that the ocean can no longer withstand continuous pollution, and we must protect the ocean. Ports, wharves, loading and unloading stations and ships that load and unload oil must prepare oil spill pollution emergency plans and be equipped with corresponding oil spill pollution emergency marine environmental protection equipment.
