With the continuous development of society, import and export trade has become more and more developed, and the sea has become a natural trade route between countries. You must not imagine that the proportion of sea transport is as high as two-thirds. To know the cargo ship loading capacity is very large, container can stack more than ten meters high, but meet the sea wind and waves will not blow apart and fall, do you know why?

Sea transport cycle is long, but why transport accounts for a high proportion?

In fact, there are only three modes of transportation for import and export trade, namely air transport, land transport and sea transport. The time period of sea transport is relatively long. After all, the speed of ships is not as fast as that of planes and trains.

But on the whole, the proportion of sea transport is much higher than that of air transport and land transport, mainly because the cost of sea transport is relatively low, this point alone, is the air transport and land transport can not compare.

In addition, a large number of goods can be loaded each time, which is higher than the load of land transport and air transport. Therefore, in international trade, sea transport has become the most common mode of transport.

What is the carrying capacity of a cargo ship at sea?

Since the age of the ship is slow, it must be recovered from the loading capacity. Then, how much cargo can the freighter carry at one sea?

It is understood that the world's largest container was developed and built by China in 2018. This cargo ship can carry more than 21,000 standard containers at most, which shows how strong its loading capacity is.

In fact, cargo ships are very different from the ships we usually see. Normally, there are two kinds of loading situation, respectively inside and on deck.

If it is in the cabin, the way to fix the container is relatively simple, most of them use the guide groove to fix, because every container is the international standard size, width and height are 8 feet, in the length of 20, 30, 40 feet of several different types.

Therefore, in the construction of container ships, the inner guide slots are designed to be fixed in size. When loading cargo, it can be put into the guide slots according to the size. In fact, this way of fixing in the tank is also the safest.

The deck is fixed in a different way, after all, there will be no fixed guide as in the cabin, but they are not randomly listed together.

Each of the boxes is tightly "set" together, and if you look closely, under each container, there is a groove that holds the two boxes together, and then a foot lock locks the boxes from top to bottom, making them one piece.

Once this is done, each row of containers on the deck will be fixed with ropes to ensure safety, so that even in stormy seas, the containers will not be blown apart.

Finally, my personal opinion:

It is not so much tying up the containers on a freighter as it is fitting them into the hull, since there are so many interests involved in containers.

Every time to go to sea is a challenge, the staff on board dare not neglect, but for the safety of containers at sea, in fact, we do not have to worry, as long as the cargo ship does not capsize, the container will not be blown apart, what do you think about this?
