As the demand for energy is ever growing the need for a cleaner source of energy arises. NG (Natural Gas) is considered to be one of the cleanest forms of fossil fuel. Natural gas when cooled to -163dec Celsius, it transforms its state to liquid, this liquefied state is referred to as liquefied natural gas (LNG). It is very convenient to transport natural gas in its liquefied state because more volume can be transported in a specified containment volume.
LNG when transported through cargo ships, the containment wall is exposed to extreme sloshing loads of the cargo, this often leads to failure of the containment wall. The main objective of the project is to develop and optimise at laboratory and demonstration scale, a monitoring system to automatically monitor the efficiency of the LNG Storage Containers and it's sub-systems.
During this PhD an intensive literature review will be carried out on the structural integrity of the vessel under its operating condition. Finite element analysis will be used to determine the nature of propagation of guided wave through very thin containment wall at cryogenic temperature and the result obtained will be validated by a laboratory based experiment.
