Device for Structural Health Monitoring of Insulation System in LNG Carriers

摘要

The present invention relates to an insulation abnormality detection device of LNG carriers, LNG carriers in the insulation of the present invention, abnormality detection apparatus, and a membrane metal panel, which is the primary barrier to direct contact with LNG, the first ply wood to take a certain load on the membrane metal panel with a first insulating material composed of polyurethane foam, the second Triplex forming a rear wall, a second heat insulating material made of polyurethane foam, in the second plywood and a cargo of an LNG cargo and insulation system consisting of a mastic for transmitting the weight of the insulation system in the hull, the first insulator and / or is installed on the inside of the second insulating material, damage to the insulation, strain, temperature and so on and selectively detects, including optical fiber sensors to detect the presence of error in real time is characterized in that the insulating material is configured. ; According to the present invention, the insulating material of the insulating material to the optical fiber sensor of the internal injury, strain, temperature sensing, etc. in real time can be accurately extra checks the insulation abnormality, to take action immediately to any error in insulation and, therefore, it is possible to significantly improve the safety of the LNG carrier.
