Many empty container parks are at capacity, and several close their doors almost daily to import de-hires of certain equipment types due to operational safety concerns (capacity/space).

Weather disruptions, berth and container terminal congestion, and stevedore industrial disputation are identified as major contributing factors. Container depots occupy an important part in the global supply chain. They manage the smooth flow of cargo for the shippers, shipping lines and forwarders and leasers in general. The container depot is contracted to consolidate the goods which are then loaded on to the ship. Apart from being a consolidation point, it is also a station for container maintenance services such as repair, cleaning or inspection. Empty containers that belong to leasing companies or shipping companies are stored here to be reused or repositioned. It is an exchange market for importers and exporters to sell or buy container assets.

A container depot can act as an extended part of the port like a satellite terminal because of its high flexibility with opening hours and access. Many times, it is a more affordable place to store containers than at the terminals at the port. When there is high congestion at the terminals, empty containers can be brought to be stored at the depot and then used for export activities. Containers that need to be repositioned can be brought to the terminal outside peak hours. Hence, the container depots act as a buffer for the terminals by storing empty containers which are a low-value activity that is taking valuable real estate at the terminals. The container depot location is an important feature. A container depot located close to the terminals helps reduce the number of transport movements.
