Forces resulting from breaking-wave impact can only be taken into account to a certain degree. When securing containers on board, the stresses resulting from the ship's movements and wind pressure must be taken into account. If the method of transporting a container is not known, then packing and securing have to be geared to the greater stresses. The above two pictures show how important it is to find out about the various carriers and their way of transporting containers, either in order to rule out certain modes of transport or to be able to match cargo securing to mode of transport. Stresses in rough seas are greater athwartships than fore and aft but the loading capacity of container end walls is lower than that of the side walls.Ĭontainers stowed both ways on board shipĮven unusual stowage methods like this, where some of the containers are stowed athwartships and others fore and aft, are used, but they require greater effort during packing and securing operations. This stowage method is not sensible with regard to the stresses in rough seas and the loading capacity of containers. This must be taken into consideration when packing containers and securing cargo. However, on many ships the containers are stowed in athwartships bays or are transported athwartships for other reasons. Stresses in rough seas are greater athwartships than fore and aft and the loading capacity of container side walls is designed to be higher than that of the end walls. This stowage method is sensible with regard to the interplay of stresses in rough seas and the loading capacity of containers. On most ships which are specially designed for container traffic, the containers are carried lengthwise:Ĭontainers stowed lengthwise fore and aft stowage on board a ship

Those actually involved with securing containers on board ships should refer to other specialist literature. This section is intended to provide the interested layperson with some basic information about how to stow and secure containers on board ocean-going vessels, so as to give him/her a better idea of the problems involved and possibly of how to select the appropriate carrier.
