Why does a huge aircraft carrier regularly clean the bottom of the ship?

As we all know, we need maintenance, so do cars, so for aircraft carriers, of course, it is no exception, and we should also clean and maintain them regularly. Many people may think that the aircraft carrier is so big and there are many machines in it. How to maintain it? What should I keep?

Because after a long voyage, a large number of marine life will parasitize the bottom of the aircraft carrier, increasing the weight of the hull and the resistance of the sea, leading to the deceleration of the aircraft carrier and increasing fuel consumption.

In fact, no matter what kind of ship, as long as it sails in the water for a period of time, a lot of seaweed will be attached to the hull, and many marine life such as shellfish and oysters will live on it. They will use the hull as a reef and make their home on it. Over time, the number of these marine life is very large. For some large ships, the marine life attached to the bottom of the ship can reach dozens of tons, which seriously drags down the power of the ship.

In fact, we all think this matter is too complicated. The bottom of an aircraft carrier needs to be maintained and cleaned most. Because the aircraft carrier often travels in the water, many creatures in the sea will be adsorbed on the bottom of the aircraft carrier. If it is not cleaned for a long time, there will be more and more organisms adsorbed on the bottom of the ship, which will cause damage to the aircraft carrier chassis and bring adverse consequences.

As long as the microorganisms at the bottom of the ship are cleaned, the algae and shellfish will be cleaned. Because the aircraft carrier is still in the water for a long time, the algae in the water will slowly grow wildly against the bottom of the ship. More and more algae will attract many shells, and most people know that shells will secrete some strong acids, which will corrode the chassis for a long time.

Because cleaning the bottom of the ship requires a lot of money and labor. Therefore, in this case, people often paint a layer of toxic substances on the bottom of the ship, so that no organisms will be adsorbed on it, but the toxic substances will always be exhausted, so some aircraft carriers need to be cleaned and maintained regularly, just to repaint a layer of paint.
