为了助力更安全、更高效的海上集装箱运输，ClassNK发布了《集装箱堆装与系固指南（第三版）》和《应对参数横摇的预防措施指南》。

ClassNK has released "Guidelines for Container Stowage and Securing Arrangements (Edition 3.0)" and "Guidelines for Parametric Roll Countermeasures" to achieve and safer and more efficient marine transportation of containers.

为了顺应集装箱船大型化发展趋势和绑扎技术的进步，《集装箱堆装与系固指南（第三版）》提供了集装箱装载和绑扎的评估方法，纳入了最新发展趋势和ClassNK的研究成果，以确保集装箱运输的安全和经济。该指南反映了在全面修订ClassNK船舶结构规范（《钢质船舶检验与建造规范和指南》C篇）期间，结合AIS的大数据和海洋数据进行的荷载分析，并将航线和季节性波动因素纳入考虑，优化系固操作。

Responding to rapid increases in the size of container ships and advances in lashing technology, the Guidelines for Container Stowage and Securing Arrangements (Edition 3.0), which have provided evaluation methods for loading and lashing containers, incorporate the latest trends and ClassNK’s R&D outcomes to ensure both safety and economy. The guidelines reflect the load analysis combined with big data from AIS and oceanographic data conducted during the comprehensive revision of ClassNK ship structural rules (Part C of its Rules and Guidance for the Survey and Construction of Steel Ships), and enable optimal stowage operations that take into account not only the route but also seasonal effects.

The Guidelines for Parametric Roll Countermeasures support the consideration of measures against parametric roll*1, which has been referred to as a factor in the recent cargo collapses on large containerships. In addition to evaluation based on Interim Guideline on the Second Generation Intact Stability Criteria (MSC.1/Circ.1627), the guidelines outline the requirements for granting notation of ships with equipment and operational parametric roll measures. They also cover a wide range of aspects, both in theory and in practice, including the mechanism of parametric roll, its features and precautions, an overview of parametric roll response calculation, and devices and methods for countermeasures such as a practical and reasonable way for creating a polar chart that illustrates the danger of parametric roll. The methods specified in these guidelines are applicable not only to container ships but also to car carriers.
