近年,海上运输量的增加推动了船舶向大型化发展,特别是对于集装箱船来说,目前正在建造装载量超万箱的超大型集装箱船。在船体结构设计中,为了确保结构安全性和可靠性,保证集装箱船甲板开口部位周围的纵向强度是非常重要的。为此,探讨了甲板周围采用超厚高强度钢板,考虑在该部位 In recent years, an increase in the volume of maritime transport has driven the development of ships to large-scale, especially for container ships, which are currently constructing very large container ships carrying over 10 000 containers. In the design of hull structures, in order to ensure structural safety and reliability, it is important to ensure the longitudinal strength around the open part of the container ship deck. To this end, discussed the use of ultra-thick high-strength steel around the deck, consider the site
