The International Association of Classification Societies has updated the North Atlantic wave scatter diagram and supplementary requirements. A series of ships, including bulk carriers, oil tankers, container ships, ore carriers, LNG carriers, PCTC ships and passenger ships, were used to analyse the influence of the updated wave scatter diagram on a ship's wave load through long-term wave load prediction. The results of the analysis show that, compared with the original North Atlantic wave scatter diagram, the new diagram and supplementary requirements have a different impact on different ship types, typically decreasing by 0~40%. The results of this study provide a reference for determining the extreme wave load of ships above the new scatter diagram.

国际船级社协会(IACS)更新了北大西洋波浪散布图及补充要求。在对比新旧波浪散布图差异的基础上,以散货船、油船、集装箱船、矿砂船、液化气体船、汽车运输船和客船等系列主流船型作为实例,通过波浪载荷长期极值预报,分析散布图更新对船舶波浪载荷的影响。结果表明:相比原北大西洋波浪散布图,新散布图及补充要求降低了船舶的波浪载荷,不同船型的影响存在一定区别,减少幅度大致在0~40%范围内。本研究结果为新散布图下的船舶波浪载荷设计极值的确定提供了参考。

国际船级社协会(IACS)更新了北大西洋波浪散布图及补充要求。在对比新旧波浪散布图差异的基础上,以散货船、油船、集装箱船、矿砂船、液化气体船、汽车运输船和客船等系列主流船型作为实例,通过波浪载荷长期极值预报,分析散布图更新对船舶波浪载荷的影响。结果表明:相比原北大西洋波浪散布图,新散布图及补充要求降低了船舶的波浪载荷,不同船型的影响存在一定区别,减少幅度大致在0~40%范围内。本研究结果为新散布图下的船舶波浪载荷设计极值的确定提供了参考。

The International Association of Classification Societies has updated the North Atlantic wave scatter diagram and supplementary requirements. A series of ships, including bulk carriers, oil tankers, container ships, ore carriers, LNG carriers, PCTC ships and passenger ships, were used to analyse the influence of the updated wave scatter diagram on a ship's wave load through long-term wave load prediction. The results of the analysis show that, compared with the original North Atlantic wave scatter diagram, the new diagram and supplementary requirements have a different impact on different ship types, typically decreasing by 0~40%. The results of this study provide a reference for determining the extreme wave load of ships above the new scatter diagram.
