What are the advantages of container ships and the structural characteristics of container ships

First of all, it can save loading and unloading labor and reduce transportation costs. Generally, cargo ships are shipped in the form of single pieces or small assemblies, which is laborious and time-consuming. The container ship adopts the international uniform specification of the container to transport goods, breaking the traditional form of single-piece loading and unloading of a bundle and a package, greatly reducing the labor intensity of stevedores, speeding up the loading and unloading, and reducing the cost of manual loading and unloading.

Second, the use of container ship transportation can reduce the loss and loss of goods and ensure the quality of transportation. This is because the goods are loaded into containers in the production plant, and they are transported by road, railway, and water on the way, and the goods can be transported directly to the user. In this way, the loss and loss of goods in transit can be reduced, and packaging costs can also be saved.

Third, container ships have high loading and unloading efficiency. The cargo loading and unloading speed of a container ship is about three times that of an ordinary cargo ship of the same tonnage, while the loading and unloading speed of a large high-speed container ship is almost 4-5 times that of an ordinary cargo ship of the same tonnage. In this way, it can reduce the time of ship docking, speed up the turnover of ships, and improve the utilization rate of ships, vehicles and other means of transportation.

A bit of a lot, mainly as follows:

1.Liner shipping.

2.Cargo security.

3 Standard Shipping.

4.Convenient shipping pricing.

5. Large load capacity, high turnover rate, reduced sea freight cost.

6. High loading and unloading efficiency, reducing terminal loading costs.

A container ship is a ship that specializes in transporting containers, also known as a container ship.

Structural features of container ships:

1. The vertical straight wall structure is adopted, the width of the cargo hatch is almost as large as the width of the cargo hold, and only a small width of the deck side plate is left on the side of the gunwale;

2. The broadside of the cargo hold area of the container ship has a double-layer shell plate, and the effective width of the cargo in the cargo hold is about the same as the width of the cargo hold. The inboard side longitudinal walls compensate for the reduction in the total longitudinal strength caused by the large openings in the deck. In addition, the broadside tanks can also improve the sinking resistance of the hull and be used as ballast water tanks;

3. The deck of the container ship is floating outward, the speed is fast, the impact force of the hull by the waves is relatively large, the impact stress caused by the waves is also relatively large, and the total longitudinal synthetic stress is also relatively large, so the bending moment value of the structure in the hull is also large, and the size of the selected components is also larger;

4. In order to load more containers, container ships are usually designed with large cargo hold openings and narrow deck slats, which makes the horizontal bending, torsional effect and lateral strength of the hull account for a significant increase in its total longitudinal strength, and there will be obvious stress concentration at the corner of the hatch;

The scale of global newly-built container ships, the structure of global newly-built container ships, and the ** index of global newly-built container ships.

In 2021, the demand for new container ships will increase significantly

From the perspective of the global newbuilding market as a whole, in 2021, the total amount of new container ship orders in the world will be the largest, exceeding 40 billion US dollars, accounting for 47% of the total new orders in the shipbuilding market in the whole year; In terms of the total deadweight tonnage of newly built ships, newly built container ships account for more than 30%. In 2021, container ships were the hottest ship type in the global newbuilding market.

According to Clarkson's statistics, in 2021, a total of 541 new container ships and 10,000 TEUs were traded worldwide, an increase of more than 300% compared with 2020.

At present, China has become the world's main container manufacturing and exporting destination. According to the General Administration of Customs of China, the number of container ships exported by China reached 99 in 2021, a year-on-year increase of 102%.

The number of newly built 10,000-container container ships accounts for a relatively high proportion

From the perspective of the number of newly built container ships of different load sizes, the number of newly-built 10,000 container ships and feeder container ships (within 500TEU) is relatively large, both exceeding 190, accounting for more than 35%; The number of new builds of medium-sized container ships is relatively small.

The index of newly built container ships** hit a new high in the past decade

Referring to the change trend of China's newly built container ship ** index CNCPI, during the period from 2011 to 2020, the CNCPI index as a whole showed a fluctuating downward trend, but it began to grow rapidly since March 2021 and reached 1025 points in February 2022, a new high in the past ten years.

The above data ** is in the Prospective Industry Research InstituteAnalysis report on market demand and investment strategic planning of China's shipbuilding industry

Summary. The basis of container ship unpacking is mainly based on factors such as the stability of the ship, the load line, the size of the hatch, the loading guide and the regulations of the shipping company. First of all, the stability of the ship is the basis of container ship management.

When sorting containers, it is necessary to calculate the number and position of containers that can be loaded in each cargo hold according to the stability of the ship to ensure the stability and safety of the ship. Secondly, the load line of container ships is also one of the important bases for container management. The load line refers to the maximum draft that the ship can withstand in different full load states, and the draft of the ship needs to be controlled to ensure that the ship will not be overloaded in the full load state.

Generally, there are "import manifests, container packing lists, ocean bills of lading, handover records, cargo lists, station receipts, and cargo imitation shelter loading Xiandamin pre-allocation lists". The basis for container import and unpacking is the import manifest or delivery record; The tally for export packing is based on the pre-provisioning list for the loading of the containerized cargo.

Dear, are you doing your homework?

Oh, yes. Kiss. I feel like it's ABCD

It's all related.

Kiss, choose C

Summary. Dear, I'm glad to answer for you. The basis of container ship unpacking is usually determined according to the relevant identification on the container hatch cover and the size of the container, as well as the type of goods, destination port, mode of transportation and other factors.

Under normal circumstances, the staff of the container ship will use professional container sorting systems and equipment according to the loading chart and planning, and reasonably distribute the containers according to the requirements of the destination port, size, weight, loading method and other requirements in a certain order to ensure the safety and stability of the goods. In addition, container ship unpacking also needs to consider factors such as loading and unloading time, circulation capacity and efficiency of loading and unloading ports, so that the goods can be kept in good condition during transportation and can reach their destination on time. Dear, that's all I'm about, I hope it helps
