How many oil spills a year?

 In the 1970s, there were 24.5 large oil spills (> 700 tons) per year, according to data published on the Internet. In the 2010s, the average number of large oil spills fell to 1.7 per year. Large spills occurred in Asia and medium spills occurred in Africa, Asia and North America. That's a slight increase from 2020, when four spills greater than or equal to 7 tons were recorded, but in line with the annual average in the 2010s. Information on accidental releases of persistent and non-persistent hydrocarbon oil since 1970, except as a result of acts of war. The data kept included the location and cause of the accident, the vessels involved, the type of oil spill and the amount of oil spilled. For historical reasons, spills are usually classified by size, <7 tons, 7-700 tons, and >700 tons (<50 barrels, 50-5,000 barrels, >5,000 barrels), but actual spills are also recorded. It now has information on more than 10,000 incidents, the vast majority of which fall into the smallest category, <7 tons. Hopetopway boom is a necessary equipment to prevent oil spill pollution in water area. To prevent oil spill pollution, the first step is to prevent the spread of oil spill. In addition to intercepting the oil spill, the boom can also guide the oil spill and make it as concentrated as possible for further recovery and treatment.

Here is the contene list:

● Oil containment booms for beach spills.

● Characteristics of booms.

● Connection of containment boom.

Oil containment booms from the beach spill.

△ Beach leakage accident containment boom can be widely used in rivers and lakes with rapid water flow and large fall, but also can be used in the ocean with large waves and fast speed. Its containment and stability are good, and it can avoid being lifted or overturned in the water flow, so as to ensure that the oil spill is collected and cleaned up. For a long time, the difficult problem that oil spill is easy to escape in practice under the condition of rapid water flow is solved. Beach spill containment boom is a kind of economical and general containment belt, which is suitable for the interception and control of oil spill and other floating objects in the quiet coastal waters. It can be fixed for a long time and has been widely used in inland pollutant discharge inlet, rivers, harbors, lakes and offshore oil drilling platforms.

Characteristics of booms.

1. Bright color, beautiful, oil resistance, sun resistance, buoyancy reserve, strong oil stagnation performance.

2. PVC double-sided road layer strong waterproof cloth is mainly used. The upper, middle and lower parts of the column are respectively equipped with pull rope, reinforcement belt and tension counterweight chain as longitudinal stress components, and the column has high tensile performance. Smooth appearance, conducive to oil conduction, easy to clean.

3. The performance and price ratio of oil boom in beach leakage accident are excellent.

4. There are different shapes of floating bodies to choose from: droplet shape (tumbler shape) is stable in rapids; Cylindrical with large buoyancy reserve, waverider; Block floating body storage volume is small, with the winding machine to distribute quickly and save labor.

5. Every 20 meters of a section, the connection between sections is convenient and fast.

The beach spill containment boom is made of PVC double-sided artificial leather, which is cheap, but its service life is not as long as that of rubber containment belt. It is suitable for river and port waters and classified according to the height of containment belt. Boom, PVC boom, solid float boom.

Connection of boom.

● The length of the booms manufactured is 30 or 20 meters per section. Generally, booms are connected to the desired length on shore or deck. Also can be connected into a certain length of containment boom into the water, with a boat to use the water area, and then the oil boom connected.

● Floating isolation device should be used at the fixed connection between the containment boom and the shore to ensure that the containment boom does not friction with the shore and prevent oil spill when the water level changes. The track of floating isolation device is vertical, and should be handled when the shore and wharf are slopes. If the bank slope is slowly changing, it is difficult to set up floating isolation device. At this time, the containment boom should be fixed at a point away from the water and above the highest working water level, and then sealed with oil absorption material. However, the containment boom is easy to wear, so it should be carefully handled. Several fixed points can also be set at different heights to adjust the fixed height.
