Container Securing
The development of containerization was a giant step forward in carrying general cargo by sea. At the time, it was correctly predicted that unit costs would fall and cargo damage become a thing of the past. In the early days of containerized transport, ships carried containers stowed on hatch covers, three or four high. A variety of lashing systems were in use. However, the most reliable system consisted of stacking cones, twist locks, lashing rods and turnbuckles (bottle screws). These systems were effective in lashing containers carried on deck to the third tier. Today, ships are bigger and a post-Panamax container ship will carry containers on deck stacked up to nine tiers high. However, while the ships are able to carry containers stacked higher, the lashing systems are still only capable of lashing to the bottom of the third tier containers or the bottom of the fourth or fifth tier containers when a lashing bridge is fitted. Ship design has developed but methods to secure containers have not.
The purpose of this guide is to discuss container securing systems, the causes of lashing failure and to offer advice as to how losses can be minimized.
