The invention discloses a whole ship framework structure of a polar region icebreaking LNG ship. A longitudinal framework type grillage structure is adopted in a non-ice area reinforcing area of the whole ship framework. An ice area reinforcing area of the whole ship framework is sequentially divided into a bow area A, a bow area A1, a midship area B, a stern area A and a stern area A1 according to borne ice loads from the bow to the stern, and the bow area A1 is divided into a bow first reinforcing area and a bow second reinforcing area. The midship area B is divided into a first midship reinforcing area and a second midship reinforcing area through a bottom horizontal line, the bow area A, the first bow reinforcing area, the first midship reinforcing area, the stern area A and the sternarea A1 are each of a transverse framework type grillage structure, and the second bow reinforcing area and the second midship reinforcing area are each of a longitudinal framework type grillage structure. The ice area reinforcing structure is more optimized in design, the ice resistance of the structure is brought into full play, and the ice area reinforcing structure has great practical value.

    本发明公开了一种极地破冰LNG船的全船骨架结构,全船骨架的非冰区加强区域采用纵骨架式板架结构;全船骨架的冰区加强区域根据承受的冰载荷从艏到艉依次划分为艏部A区域、艏部A1区域、舯部B区域、艉部A区域和艉部A1区域,所述艏部A1区域划分为艏部第一加强区和艏部第二加强区,所述舯部B区域通过底平线划分为舯部第一加强区和舯部第二加强区,所述艏部A区域、艏部第一加强区、舯部第一加强区、艉部A区域和艉部A1区域均采用横骨架式板架结构,所述艏部第二加强区、舯部第二加强区均采用纵骨架式板架结构。本发明的冰区加强结构设计更为优化,结构抗冰性能得到最大发挥,具有很大的实用价值。
