多用途重吊船结构设计特点

由于货物装载的多样,故一些多用途重吊船货舱有着平直的舷侧结构,并要求更长的货舱。这种相对疲弱的结构给设计带来难度。根据多用途船的装载特点,通过结构规范设计、工况评估及有限元强度计算(包括屈服强度、屈曲强度和疲劳评估),阐述了此种船型的船体设计要点和评估方法,以正确、现实、合理的反映多用途船的结构设计理念。

Overview of Hull Design for Heavy Lift Multi-purpose Vessel

Nowadays,heavy lift multi-purpose cargo ships were featured with large cargo hold and straight and flush side walls which resulted in relatively weak and soft cargo hold structure. This brought challenges for structure design. Hence a brief introduction on overview and characteristics of the hull design was given by describing design aspects , load condition and FEM evaluation (including yielding,buckling and fatigue strength). Key points were summarized to reflect the structure design philosophy for heavy lift multi-purpose vessel in a physically correct ,practical and reasonable manner.
