According to the novel shell continuous C-shaped storage cabin liquid dome, a C-shaped storage cabin is located below a deck, and the liquid dome is arranged at the top of the C-shaped storage cabin. The liquid dome is divided into an upper section and a lower section, the diameter of the upper section liquid dome is smaller than that of the lower section liquid dome, the upper section liquid dome and the lower section liquid dome are connected into a whole through the middle section coaming, a top plate is sealed at the top of the upper section liquid dome, a bottom plate is sealed at the bottom of the lower section liquid dome, and the edge of the bottom plate and the cabin wall of the C-shaped storage cabin are connected into a whole. A plurality of cabin penetrating openings are formed in the bottom plate, the multiple sections of cabin penetrating pipe systems extend upwards through the cabin penetrating openings and penetrate through the top plate to the position above the deck, and the cabin penetrating pipe systems and the bottom plate are welded and fixed. A storage tank shell can be kept as a closed space, a main pressure-bearing structure of a pressure container is formed, and a secondary protection space is formed in the novel liquid dome structure, so that the size of a storage tank opening can be reduced while liquid cargo system operation conditions and piping system arrangement requirements are met, the structural stress at the position is reduced, and the service life of the storage tank is prolonged. The structural safety and the designability of the storage cabin structure are improved, and construction is more convenient.

    一种新型的壳体连续C型储舱液穹,C型储舱位于甲板下方,C型储舱顶部设置有液穹。液穹分为上下两段,上段液穹的直径小于下段液穹的直径,上段液穹与下段液穹通过中段围板连接成一体,上段液穹的顶部封有顶板,下段液穹的底部封有底板,底板边缘与C型储舱的舱壁连结成一体。底板上开有多个穿舱口,多段穿舱管系经由穿舱口向上延伸,穿透顶板至甲板上方,穿舱管系与底板焊接固定。本发明可保持储罐外壳为密闭空间,形成压力容器的主承压结构,在新型液穹结构内部形成二次保护空间,如此,可在满足液货系统作业条件、管系布置需求的同时,降低储舱开孔大小,从而降低此处结构应力,提高结构安全性和储舱结构的可设计性,且更加便于施工。
