DNV GL新规范对大型集装箱船结构设计的影响

从总纵强度、舱段有限元和典型结构局部强度三个方面解析了DNVGL规范与GL规范在集装箱船结构方面的内容差异。以一艘14500TEU集装箱船为算例，分析了DNVGL规范对大型集装箱船结构设计的影响。结果表明，DNVGL规范对于集装箱船的总纵强度和舱段有限元提出了更高的要求，而在压载舱边界结构和艏部砰击方面的要求相对于GL规范有所降低，存在一定的优化空间。

Analysis of Impact of new DNVGL rules on structural Design for Large Container Ship

The content difference between DNV GL and GL rules in the structure of container ships are analyzed in terms of global longitudinal strength, cargo hold finite element analysis and local strength of typical structure. Taking a 14500TEU container ship as an example, the influence of DNV GL rules on the structure design of large container ship are analyzed. The results show that DNV GL rules present higher requirements for the global longitudinal strength and cargo hold finite element of the container ship, the requirements for the ballast tank boundary structures and slamming for forward bottom structures are lower than GL rules, which have some optimization space.
