Design and use of semi-rigid 40 'containers for top-loading and watertight closure with a fixed steel roof to replace standard 20' containers and maritime transport innovation with maximum standardization to 40 'standard

摘要

With the redesign and use of semi-open top lockable 40 'containers, further standardization will be made possible for sea transport between 20' and 40 'with a maximized proportion of standard 40' containers. The replacement of the 20 'standard containers by using the half-height 40' containers is achieved by the fact that the space and payload weights of the two containers almost match. In addition, two half-height 40 'containers stacked on top of each other can be technically connected as one unit to the space of a standard 40' container. The maximization of the 40'Norm opens up a significant streamlining potential. In addition to logistical effects, this is mainly due to the reduction of investment due to lower demand for 20 'containers and equipment and operational costs due to increased productivity.
