The LNG ship cargo hold bottom structure comprises a pipe tunnel area and a ballast tank area, the pipe tunnel area is arranged on the center line of a ship body, the pipe tunnel area is symmetrically arranged about the center line of the ship body, the distance between pipe tunnel longitudinal girders on the two sides of the pipe tunnel area is smaller than 5000 mm, and the ballast tank area is arranged between the pipe tunnel longitudinal girders on the two sides of the pipe tunnel area. A channel is arranged in the pipe tunnel area along the center line of the ship body, a plurality of new side longitudinal girders are arranged in the ballast tank areas on the two sides of the pipe tunnel area, and the new side longitudinal girders are located between the side longitudinal girders closest to the pipe tunnel longitudinal girders and the pipe tunnel longitudinal girders. Compared with an LNG ship cargo hold bottom in the prior art, a middle longitudinal girder arranged on the center line of the ship body is omitted, the size of a ballast tank area is increased, the bearing capacity of the LNG cargo hold bottom is guaranteed, and the technical problems that welding is not easy and deformation is prone to occurring due to the fact that the middle longitudinal girder is thickened are solved.
本发明公开了一种LNG船货舱底部结构,所述LNG船货舱底部结构包括管弄区域和压载舱区域,所述管弄区域设置于船体中心线上,且管弄区域关于船体中心线对称设置,管弄区域两侧的管弄纵桁之间的距离小于5000mm,在管弄区域内沿着船体中心线设置有通道,在管弄区域两侧的压载舱区域内设置有多个新边纵桁,所述新边纵桁位于离管弄纵桁最近的边纵桁与管弄纵桁之间。本发明相比较于现有技术中的LNG船货舱底部,取消了设置在船体中心线上的中纵桁,不仅增大了压载舱区域的体积,而且还保证了LNG货舱底部的承载能力,避免了加粗中纵桁带来的不易焊接和易变形的技术问题。
