The carrier should clean the bottom of the ship regularly. Why? What happens if you don't clean it up?

Any ship, steel, wood, FRP, etc. After being immersed in seawater for a long time, it will attach to marine life, plants or animals, or both. Excessive attachment of these marine organisms will affect the speed of the ship, increase fuel consumption and even corrode the hull. Therefore, taking steel ships as an example, it is required to dock or paddle regularly, or explore underwater, video and check the attachment of marine life on the hull. After docking, manually remove the attachments, then clean the hull with sprayed ore, and then spray paint for protection. The paint commonly used in the outermost layer is called antifouling paint, which is highly toxic and can prevent marine life from adhering. With the release of the toxicity of antifouling paint, the toxicity is getting lower and lower, and marine life will still adhere. Ships sail alternately in fresh water and seawater, and there are relatively few marine life. Different sea areas will have different marine life growth. It is recommended not to eat marine life attached to the bottom of the ship, which is easy to be poisoned! Look at the problem from another angle. Why doesn't the aircraft carrier clean up the ship? Everything is reasonable, which means it must be reasonable to clean the bottom of the aircraft carrier. You know, in many cases, not only the aircraft carrier needs to clean the bottom of the ship, but actually most ships need to clean the bottom of the ship.

We know that even if river pebbles are immersed in seawater for a long time, marine life such as moss is inevitable, especially ships. Friends who are close to the seaside know that mosses and shell snails are bound to grow on ships that are used all the year round. Similarly, aircraft carriers are no exception. Imagine that a small boat often uses these things at the bottom, so there are more aircraft carriers. In this way, if it is not cleaned up, it will accumulate to a certain extent, and whether the weight of the aircraft carrier will gradually increase, thus affecting the performance of the aircraft carrier in all aspects. Meanwhile, another purpose of cleaning the aircraft carrier is to maintain the bottom of the aircraft carrier. No matter how many years of special materials, they will certainly not come to a good end under the day-to-day erosion of seawater, so this time it is also a good maintenance for the bottom of the aircraft carrier. At the same time, to popularize it for everyone, the aircraft carrier will not only clean the bottom regularly, but also clean its aircraft carrier deck regularly, which is equivalent to regular maintenance of the aircraft carrier.
