What are different types of container used on ships ?

There are many container types in operation to suit a variety of trades. Sizes also vary and they can be shipped in the following sizes: 8 ft in width and 8 ft or 8 ft 6 inch in height, with lengths of 10, 20, 40 or 45 ft.

Conventional units (general purpose) –

Also known as a dry container are made from steel and fully enclosed with a timber floor. Cargo-securing lashing points are located at floor level at the base of the side panelling. Access for ‘stuffing’ and ‘de-stuffing’ is through full height twin locking doors at one end.

Open top containers –

Half-height containers –

An open top container which is 4 ft 3 inch in height, i.e. half the standard height of a general purpose container. They were designed for the carriage of dense cargoes such as steel ingots, or heavy steel cargoes or stone, etc. since these cargoes take up comparatively little space in relation to their weight, two half-height containers occupying the same space as the standard unit.

Flat rack container –

This is a flat bed with fixed or collapsible ends and no roof. They are used to accommodate cargoes of non-compatible dimensions or special cargoes that require additional ventilation.

Bulk container –

Bulk containers are containers designed to carry free flowing cargoes like grain, sugar or cement.
