The invention discloses a gas-liquid combined dome structure for a B-type LNG fuel cabin of a dual-fuel ultra-large container ship, the gas-liquid combined dome structure is located at the position, close to the stern end, of the center above the top of the B-type LNG fuel cabin, a main body peripheral structure of the gas-liquid combined dome structure comprises an enclosure bulkhead (2) and a top cover plate (3), and a horizontally-arranged cabin penetrating interlayer (4) and a vertical channel well wall (5) are arranged in the gas-liquid combined dome structure; the main body structures are connected with a B-type LNG fuel cabin top plate (1) in a welded mode, and the whole main body structures are located above a cross-shaped strong structure composed of a longitudinal girder and a transverse strong frame in the top of the B-type LNG fuel cabin. According to the gas-liquid combined dome structure, the arrangement requirements of all cabin penetrating pipe fittings in the LNG fuel cabin and the maintenance and passing requirements of personnel and equipment are met in a limited space, redundant structures are reduced as much as possible while the strength of the dome structure is guaranteed, and the gas-liquid combined dome structure has very high practical value.

    本发明公开了一种用于双燃料超大型集装箱船的B型LNG燃料舱的气液组合穹顶结构,所述气液组合穹顶结构位于B型LNG燃料舱的顶部上方中央靠艉端的位置,其主体外围结构包括围壁(2)和顶盖板(3),内部有水平布置的穿舱夹层(4)和垂向的通道井壁(5),这些主体结构与B型LNG燃料舱顶板(1)焊接连接,整体坐落在B型LNG燃料舱的顶部中纵桁和横向强框架组成的十字交叉状强结构上方。本发明提供的这种气液组合穹顶结构使得在有限的空间内实现了LNG燃料舱里所有穿舱管件的布置要求与人员设备的检修通行要求,在保障穹顶结构本身强度的同时又尽量减少了冗余结构,具有非常大的实用价值。
