Sea freight is the most cost-effective but time-consuming form of transport. In most cases, companies require additional modes of transport alongside sea freight, as ships deliver cargo only to ports. For inland transport, other transportation methods are used.
In maritime transport, special cargo containers (ISO containers) are used. These containers have a robust construction to withstand significant forces and ensure that the cargo inside remains undamaged.
A universal or intermodal container is a large, standardized container designed for storing cargo in combined (intermodal) transport—transport that involves transferring between different modes such as road, rail, and sea. Standardization improves transport efficiency by allowing the same infrastructure to handle various types of cargo. A key feature of universal containers is their ability to stack and secure using special fittings at each corner.
The vast majority of global container traffic is carried out using general-purpose dry cargo containers, which are durable steel boxes with standard dimensions of approximately 6.1 meters (20 feet) or 12.2 meters (40 feet) in length.
High Cube containers (HC) are structurally similar to standard containers but are taller. The maximum height of a standard container is 2,591 mm (8'6"), while a High Cube container measures 2,896 mm (9'6"). High Cube containers are usually 40 feet long, but 45-foot versions are also available.
Open Top containers (OTC) are typically made of corrugated steel with wooden floors. The roof is replaced by a removable "tarpaulin," which simplifies the loading and unloading process. The container can be easily unloaded from above or through the doors using a crane or hoist when the roof is removed.
Refrigerated containers (RF) are used for cargo that requires a constant temperature above or below freezing. This cargo is categorized as either chilled or frozen, depending on the required temperature. Such conditions are crucial for transporting fruits, vegetables, meat, and dairy products.
The appropriate atmosphere in the container is established by flushing it with nitrogen and carbon dioxide. During transport, the atmosphere is regulated with nitrogen flushing or by adding carbon dioxide and ethylene.
Refrigerated and insulated containers are available in sizes of 20 feet and 40 feet.
Flat Rack containers (FR) consist of a high-strength floor construction, a robust steel frame, and a softwood floor, with two end walls that can be either fixed or collapsible. The end walls are stable enough to secure the cargo and allow stacking of multiple Flat Rack containers. These containers are available in sizes of 20 feet and 40 feet.
