In case that the vessel is equipped with lashing bridges the symmetrical arrangement of containers in longitudinal direction is even more important. Shipowner’s requirement for unified length of lashing rods is always extremely difficult to fulfil when the vessel has lashing bridges because a container height difference of at least 2 x 305 mm has to be considered for high cube container loading. It is very difficult to handle extension rods from lashing bridges therefore they should not be used. The longitudinal gap between lashing bridges and 20’ container end should be minimized as much as possible and 40’ containers always to be arranged symmetrically in order to reduce 3D-effect of lashings. During torsion of hull the container stack will shift together with the hatch cover panels in relation to the lashing points on lashing bridge creating additional forces in the lashings. This effect is increasing as more as the lashings are inclined in longitudinal direction.
