Sea freight container This refers to a new, highly efficient, and effective transportation method that uses large containers such as shipping containers as carriers. Goods are assembled into container units, allowing for loading and unloading with large handling machinery and large transport vehicles in the modern distribution field, completing transportation tasks and better achieving door-to-door transportation of goods.

　　Containers have the following conditions: they can be reused repeatedly for a long time, have sufficient strength and rigidity, have loading and unloading devices, are easy for mechanical loading and unloading, can be conveniently and directly replaced and fixed between various modes of transport, and do not require unpacking and repacking, facilitating full loading and unloading of goods.

　　Although container transport is a modern mode of transportation, its development has gone through a long process. The characteristics of sea freight container transport entering the mature stage are mainly reflected in the following two aspects:

　　The supporting hardware and software technologies are becoming more mature. Full-line container ships are developing towards full automation and large-scale operations. Third-generation and fourth-generation sea freight container ships with capacities of 2500-4000 TEUs have emerged. Some large shipping companies have already used large ships to organize global routes. To meet the needs of large ships berthing and loading and unloading, ports are becoming larger and faster. Automatic gantry cranes have also been further developed. To extend container transport from ports inland, some developed countries have built a large number of supporting facilities such as inland roads, railways, transfer stations, vehicles, and ships.

　　In terms of transportation management, with the improvement of international regulations and the gradual formation of internationalized management, the management methods have become scientific and the management means have become modernized. Some developed countries have developed from port area management to comprehensive information management connected with relevant port departments, and some large companies are already able to track and manage containers worldwide through communication satellites. Domestic advanced Sea freight container Transportation technology has laid a good foundation for the development of multimodal transport.

　　Entering the stage of multimodal transport and "door-to-door" transport. Realizing the intermodal transport of various modes of transport is the development direction of modern transport, and sea freight container transport has unique advantages in this regard. Developed countries have established and improved the container integrated transport system, enabling container transport to break through the concept of traditional methods, comprehensively utilizing the advantages of various modes of transport, providing door-to-door high-quality services to cargo owners, and giving full play to the advantages of container transport. "Door-to-door" is a complex international system project. In order to develop container transport, developed countries have cultivated a large number of senior management, business, and operational personnel for sea freight container transport, enabling the theory and practice of container transport to be gradually improved.
