Container shipping is a modern logistics method that forms the basis of global trade. It enables goods to be transported more safely, quickly, and at a lower cost. The development of this system has fundamentally changed world trade. Container shipping is a logistics method in which goods are transported in standardized metal boxes (containers). These boxes can be easily loaded and unloaded on ships, trains, and trucks. The most common container types are 20-foot TEU (Twenty-foot Equivalent Unit) and 40-foot (Forty-foot Equivalent) containers.
Container shipping, which is actively used today, has gone through several stages to reach its current version. Initially, there was no single type of container, and over time, the ISO (International Organization for Standardization) standardized container sizes and connection systems. This made it possible to use the same container anywhere in the world without any difficulties. With advances in technology and fuel efficiency, containers can now be transported much more efficiently using mega ships capable of carrying over 18,000 TEUs.
The standardization of containers has many advantages.
Advantages of Container Standardization:
- High efficiency
- Less handling (loading/unloading)
- Lower risk of damage and loss
- Continuity in transportation (intermodal transport: sea + road + rail)
Container shipping can be summarized in different areas. Below we review the different eras of container shipping.
The First Era: The Beginning of Container Use
- 1956: An American businessman named Malcolm McLean launched the first container ship (SS Ideal X) for cargo transport.
- This method significantly reduced loading and unloading times and costs.
- Initially used only in the U.S., this method later spread to Europe and Asia.
The Second ERA: Standardization and Spread
- The ISO (International Organization for Standardization) standardized container sizes and connection systems.
- Ports began installing special cranes, terminal equipment, and infrastructure for containers.
- The volume of international trade increased rapidly.
- Container ships grew larger; the first full container ships appeared during this period.
The Third ERA: Technology and Logistics Integration
- Intermodal transportation became widespread: containers could be transported by sea, road, and rail.
- Satellite tracking systems, automatic cranes, and ERP software began to be used.
- Major global container shipping companies have emerged (Maersk, MSC, CMA CGM, etc.)
Highlights by ERA
- 1950s: The first containerized transportation begins
- 1970s-80s: Industrialization and global spread of container shipping
- 1990s-2000s: Intermodal system emerges, and integration accelerates
What’s next for container shipping?
Nowadays, technologies such as autonomous, semi-autonomous, and the Internet of Things (IOT) are being integrated into container shipping. There is no standardization in this area yet, but with the development of artificial intelligence, a new era in container shipping is about to begin.
The global container ship fleet (i.e., the number of ships carrying containers) is expected to be around 6,500–7,000 by the end of 2025 (per Alphaliner.) According to BIMCO reports for early/mid-2024, the total capacity of the container fleet was approximately 30.4 million TEU (per BIMCO.) Additionally, in terms of tank containers (the type of container used for transporting chemicals and liquids) alone, the global tank container fleet was reported to be approximately 801,800 units as of January 1, 2023 (per ITC.)
