A vertical installation structure of a marine LNG storage tank comprises a storage tank body vertically fixed to a ship body, a peripheral anti-roll and anti-rotation device, a bearing installation device and an expansion joint, and stress generated by temperature field change or ship vibration is absorbed through the expansion joint; an anti-roll and anti-rotation device is mounted on the tank body of the storage tank, so that the storage tank can be prevented from rotating due to uneven stress in the marching process of the ship; the bearing installation device bears the weight of the whole storage tank and the whole FGSS ROOM and is responsible for connecting the whole FGSS ROOM with a ship, the vertical storage tank is stably and conveniently installed on the ship through the structure, the vertical installation mode is more flexible, vertical installation is achieved, the influence of shaking on the liquid level is small, stress generated by temperature field changes or ship vibration is absorbed through an expansion joint, and the stability of the storage tank is improved. The gas supply system equipment can be prevented from being damaged, and the system has the characteristics of stability, reliability, simple device and cost reduction.
一种船用LNG储罐立式安装结构,包括立式固定在船体上的储罐体,外围防侧倾防旋转装置、承重安装装置和膨胀节,通过膨胀节吸收因温度场变化或船舶震动产生的应力;储罐罐体上安装防侧倾防旋转装置,可防止储罐在船舶行进过程中因受力不均而发生旋转;承重安装装置承担整体储罐及FGSS ROOM整体的重量,负责整体与船舶相连接,该结构将立式储罐稳定且方便的安装在船舶上,立式安装方式更加灵活,立式安装,晃荡对液位影响较小,通过膨胀节吸收因温度场变化或船舶震动产生的应力,可避免危害供气系统设备,系统具有稳定可靠、装置简单、降低成本的特点。
