For sea freight transportation containers of various capacities made of weather-resistant Corten steel are used. Such containers are used to transport non-perishable products and large-sized cargo, for example, motorcycles from Japan to Odessa are delivered by sea freight. The optimal and most common sizes of sea containers are 20 and 40 feet, containers of 10 and 45 feet are less commonly used due to their non-standard nature. Types of cargo containers for sea transportation:
Standart (Dry Van, General Purpose). Universal marine shipping containers будь-яких вантажів.
High Cube (HC). A container with an increased height of one foot compared to standard types of containers. Suitable for transporting all types of cargo, usually of non-standard sizes.
Pallet Wide (PW). This type of container has a wider base compared to the standard size. It is designed for transporting palletized cargo. Due to the increased width, it can accommodate 2 pallets of 120 cm each.
Open-Top (ОТ). An open-top container with a tarpaulin roof. This container is suitable for transporting cargo that does not fit into other containers due to its height.
Hard-Top (HT). Equipped with an opening metal roof, allowing loading from above (when a crane is used for loading). Suitable for transporting oversized cargo and complex structures, such as industrial equipment.
Upgraded (UP). It is characterized by increased load-bearing capacity, which is achieved due to the increased strength of the base.
Flat Rack (FR) і Platform (PL). — platform-type containers. They are an open platform designed for transporting “extra heavy” oversized cargo, such as special equipment, heavy industry products, and building materials (concrete blocks).
Types and sizes of 20-foot sea container:
All of the above types of containers for sea transportation are presented in sizes of 20 and 40 feet. The size of a 20-foot sea container may vary depending on the type of container:
Standard. The container provides moisture and dust protection, is suitable for both transportation and long-term storage of goods. The cargo is placed inside the container through a wide door at the end. 20-foot containers can hold a cargo volume of up to 34 m³, the maximum load is up to 22 tons. The weight of the container is 2 tons.
Platform container. It is distinguished by the absence of side walls and a roof, the containers have only end walls that provide support and protection of the cargo, thus, there is no lateral load on the container. This design allows loading of large-sized cargo and makes any types of loading and unloading operations convenient. The container capacity is up to 28 m³, the maximum load is 27.5 tons. Despite the absence of side walls, the weight of the container is more than the standard one - 2.9 tons.
Open. Containers with a removable hard or soft lid allow loading of large-sized cargo in a vertical position through the roof, which makes loading possible using a crane. The container weighs 2.4 tons, holds up to 32 m³ of cargo, and provides a maximum load of 22.5 tons.
Refrigerated. This type of container is equipped with special regulating equipment, which allows to provide and maintain a certain temperature regime during transportation. The volume of the containers is small - 28 m³, they can withstand a load of up to 24 tons with a container weight of 3 tons. Usually, perishable products are transported in such containers.
40-foot containers
40-foot containers are no less in demand for dry cargo and other maritime transportation than 20-foot ones. They have a larger capacity, which allows you to transport larger cargo and large batches of goods. The dimensions of a 40-foot container also vary depending on the type:
Standard. The container is suitable for moving large-sized cargo. It provides a large capacity of 67.7 m³ and a loading capacity of 26.5 tons with a tare weight of 3.9 tons.
Open. A 40-foot open-top container holds 66.7 m³ of cargo with a maximum load of 31.7 tons. The weight of the container is almost 2 times greater than that of a 20-foot container — 4.4 tons.
Platform container. The length of a 40-foot platform container is 12 meters with a standard width and height, the weight of the container is greater than the above - 5.5 tons. The container has a capacity of 54.8 m³ and a maximum load of 39.4 tons.
Refrigerated. A 40-foot temperature-controlled container can hold up to 60.2 m³ of cargo and withstand a maximum load of up to 26 tons. Such a container is often used as a cold storage for storing and transporting large batches of products with a limited shelf life. The weight of the refrigerated container is 3.7 tons.
Large capacity container. The High Cube container has an increased height capacity and a load capacity of over 30 tons. The container holds up to 76.4 m³ of cargo, while weighing less than many 40-foot containers — 4.1 tons.
Refrigerated with increased capacity. Such a container has an additional capacity of up to 5 thousand kg and is 66.1 m³. The container also supports various temperature modes - cooling, freezing, heating. The weight of the container is 4.2 tons.
Cargo tank container and its types.
A small role in logistics is given to tank containers, which are a tank for transporting various liquids and liquefied gases. The capacity of such tanks varies from 26 to 35 m³. Sometimes they are equipped with steam heating or thermal insulation to maintain the temperature of the transported liquid. Tank containers for cargo are presented in several types:
IMO0. Designed for transporting liquid food cargoes, such as milk, juices, mineral waters. The capacity of the tanks is 20-30 thousand liters, and the wall thickness is within 2 mm.
IMO1. Designed for transporting dangerous goods (flammable and oxidizing materials, aggressive and toxic substances, other dangerous liquids). Tanks from 14 to 30 thousand liters, the thickness of the tank walls reaches 8 mm.
IMO2. Used for transporting non-hazardous cargo (substances with low toxicity and corrosive liquids). Tank capacity - 21-30 thousand liters, wall thickness 3-4 mm.
IMO5. They are used for transporting liquefied and compressed gas, as well as other flammable liquids with a working pressure in the container of more than 7 bar (pressure in other containers from 2 to 6 bar).
