Anti-leakage marine LNG fuel tank

The invention discloses a leakage-proof marine LNG fuel tank, which considers that leakage is caused by long-term fatigue no matter which mode is adopted to reinforce or reinforce a liquid phase pipe, so that in the technical scheme of the invention, the performance of the liquid phase pipe is monitored in real time, and the leakage-proof marine LNG fuel tank has the advantages that the performance of the liquid phase pipe is monitored in real time; when the performance of the liquid phase pipe is detected not to meet the application requirement, the liquid phase pipe is replaced or maintained in time, so that the hidden danger of leakage is eliminated before leakage occurs. That is to say, in the technical scheme of the application, the anti-leakage capability of the marine LNG fuel tank is improved by adopting a soft anti-leakage scheme. 本申请公开了一种防泄漏船用LNG燃料罐，其考虑到不管采用何种方式对所述液相管进行加固或者加强，其都会因长期的疲劳而导致泄漏的发生，因此，在本申请的技术方案中，对所述液相管的性能进行实时监测，以在检测到所述液相管的性能无法满足应用要求时，进行及时地更换或者维修保养，以在泄漏发生前，将泄漏的隐患消除。也就是说，在本申请的技术方案中，采用"软防泄漏
