Ocean Freight Container Types:

End loading, Fully Enclosed
The basic intermodal container with end doors, suitable for general cargo not requiring environmental control while enroute.

Side Loading, Fully Enclosed
Equipped with side doors for use in stowing and discharge of cargo where it is not practical to use end doors,
as when the container must remain on a rail car while cargo is placed in or removed from the container.

Open Top
Used for carriage of heavy, bulky or awkward items where loading or discharge of the cargo through end or side
doors is not practical. Most open top containers are equipped with fabric covers and are often termed "soft" or "rag" top
containers. Some open top versions are fitted with removable hatch type panel covers or detachable full metal roof.

Ventilated
Equipped with ventilating ports on ends or sides, and used for heat generating cargo or cargo requiring protection from
condensation (sweat) damage. Versions with powered air-circulating fans are available. Vents are normally fitted with
baffles to prevent entry of sea or rain water.

Insulated
For cargo that should not be exposed to rapid or sudden temperature changes. Available in ventilated or non-ventilated
versions. Some carriers provide container with heating systems for special applications.

Refrigerated
Insulated and equipped with a built-in refrigeration system, powered by direct electrical connection or by diesel or
gasoline generator. It is used primarily for foods or other commodities requiring a temperature controlled environment.

Liquid Bulk
Tank-type containers for carriage of liquids. Some have been designed to high level specifications for carriage of certain
hazardous materials.

Dry Bulk
Designed for carriage of bulk cargo such as dry chemicals and grains.

Flat Rack
Available in a variety of sizes and models, the flat racks are used for lumber, mill products, large, heavy bulky items,
machinery and vehicles. Some are equipped with removable sides.

Auto
Used for carriage of vehicles and available in enclosed or open versions.

Livestock
Configured for the nature of livestock carrier; containers are available for transporting poultry, cattle and other livestock.

Sea Shed
Experimental open-top container developed by MARAD and the U.S. Navy. This cargo handling system is designed to
adapt containers-ships to the carriage of heavy, outsized equipment (notably military). The "work-through" floor
construction (floor section opened by a self-contained winch) can reduce unloading time and pier side storage space
since they need not be removed at destination.

High - Cube
These containers are used for high volume/low weight cargo and can greatly increase the cubic area available for cargo
stowage. High cube containers are in heights to 9.5 feet and to lengths of a maximum of 48 feet.

Garment
With special tie downs and internal ceiling fittings, this container can handle hanging garments.
