Container terminals can have for the same surface a significant variation in the stacking density because of the type of container yard equipment. The most common are rubber-tired gantries and straddle carriers, which are associated with average stacking densities; between 500 and 1,000 TEU per hectare of yard space. The choice of stacking density is the outcome of the available terminal footprint and the complexity of terminal operations. Low densities have the advantage of quick turnaround but consume more yard space. In contrast, high densities are logistically more complex and require careful operations to avoid an undue amount of container rehandling.
