The invention provides a B-type cabin and a ship, and relates to the technical field of oil and gas storage and transportation, and the B-type cabin comprises a shell and an enclosure system. The shell is formed by welding a plurality of partition plates, a containing cavity for containing LNG liquid is formed in the shell, and a welding seam is arranged between any two adjacent partition plates. The enclosure system comprises a flow guide groove formed by bonding a plurality of heat insulation bricks, the extending direction of the flow guide groove is the same as that of the weld joints, the flow guide groove and the shell are connected to define a leakage channel, all the weld joints are located in the leakage channel, and meanwhile the leakage channel is communicated with the outside. The enclosure system further comprises a first heat insulation layer connected with the shell. Through the arrangement of the leakage channel, when a welding seam is damaged, LNG liquid enters the leakage channel, meanwhile, due to the fact that the leakage channel is further communicated with the outside, the LNG liquid in the leakage channel can be volatilized into the outside air, and the ship body cannot be eroded.
本发明提供了一种B型舱及船舶,涉及油气储运的技术领域,B型舱,包括:外壳和围护系统。外壳由多块隔板焊接形成,外壳内形成有盛装LNG液体的容纳腔,任意相邻两块隔板之间设有焊缝。围护系统包括由多块隔热砖相互粘接形成的导流槽,导流槽的延伸方向与焊缝的延伸方向相同,导流槽与外壳相连围成泄漏通道,且全部焊缝位于泄漏通道内,同时泄漏通道与外界连通。围护系统还包括第一隔热层,第一隔热层与外壳相连。通过设置泄漏通道,当焊缝发生破损后,LNG液体进入到泄漏通道内,同时,由于泄漏通道还与外界连通,在泄漏通道内的LNG液体会挥发到外界空气中,不会对船体侵蚀。
