SEC Bremen: оборудования для крепления контейнеров

External Lashing Systems July 2014 © Technical alterations reserved 2.14 In case of large container vessel with lots of container tiers on deck and high stackloads normally the stackload/weight distribution is limited by the allowed corner post compression acting on the lowermost container. Traditional internal lashings will produce additional pressure forces at the pressure side of container stack, thus additional lashing units would make situation even worse instead of improving safety. As an alternative container stacks can be lashed externally. In such case the lashing forces are reducing the tension forces on tension side of container stack without increasing pressure forces on the pressure side of stack. There is considerable improvement of stackload and weight distribution but on the other hand external lashing systems are very complex and difficult to handle. Interference in way of turnbuckles but also in way of rod heads have to checked for hundreds of different loading conditions of 8’6’’ and 9’6’’container height. A certain sequence has to be strictly followed when installing the lashing units.
