Cargo determines the main function, transportation mode, and related characters required for the container port. In container port design, the object cargo is an intermodal container. Containers are usually classified as 20-foot and 40-foot. 53-foot containers were introduced and used both in the US and Canada, mainly for domestic road and rail ...

The fairway depth of a river varies with the season, so some standardized depth value is used, usually the one corresponding to the low navigable water level (LNWL) defined as the water level that the river stays above during almost the entire navigation season: statistically, the level shall stay below the LNWL for 20 ice-free days per year ...
However, the mean sea level (MSL) observed in the port area is 2.8 metres (9.2 ft), which increases the depth of the approach channel and harbour. [8] The depth of the inner channel and manoeuvring area will be more than 19.5 metres (64 ft) with minimum tidal advantage; vessels with a draft of 16.5 metres (54 ft) are capable of navigating in ...
The Port of Ngqura is South Africa's newest port and the deepest container port in the country. It has an entrance channel -18 m Port Chart Datum in depth, a turning basin of 600 m in diameter and also at -18 m Port Chart Datum, 1 general cargo berth at -18 m Port Chart Datum, and 4 container berth and 2 general cargo berth at -16 m Port Chart Datum.
Larger container ships instead need 14 m (46 ft) to carry full loads. The PoMC estimated that in the 2006-07 financial year, 38.5% of ships visiting the port was already potentially affected by draught limitations because the channel did not allow for the extra depth, with this figure rising to 44.3% in the December quarter of 2007.

Conceptual designs for the North Carolina International Terminal called for a high-density, automated container terminal capable of serving 12,000-TEU vessels with at least a 50-foot draft (the existing navigation channel serving the Port of Wilmington in the Wilmington Harbor has a dredge depth of 42 (+/-) feet).
By the late 1960s, the Port of Oakland was the second-largest port in the world in terms of container tonnage. However, depth and navigation restrictions in San Francisco Bay limited its capacity, and by the late 1970s, it had been supplanted by the Ports of Los Angeles and Long Beach as the major container port on the West Coast.
