Abstract	With tightening environmental regulations, demand for eco-friendly fuels has been increasing, driving a steady rise in orders for LNG-fueled ships and LNG carriers. In particular, the demand for membrane-type LNG carriers, which offer excellent safety and economic efficiency, has been growing significantly. However, sloshing during operation significantly impacts the structural integrity of cargo tanks, and high-amplitude sloshing loads can cause permanent damage. Traditional linear-based sloshing assessment methods provide conservative, relatively safe results but fail to capture the nonlinear characteristics of actual sloshing loads adequately. Although several classification societies have proposed assessment procedures that incorporate structural nonlinearity, further refinement is required for practical application. In this study, an improved sloshing assessment methodology that considers structural nonlinearity was proposed, based on Lloyd's Register (LR) procedures, and applied to the MARK III Flex cargo containment system (CCS) of a 174K LNG carrier. Model tests were conducted to define the expected ranges of peak pressure and rising time. In addition, numerical simulations incorporating strain-rate effects and the plastic deformation behavior of R-PUF (reinforced polyurethane foam) under sloshing loads were performed, and the predicted dynamic responses were validated against experimental results. Furthermore, empirical formulations of the dynamic response factor were derived for different failure modes of CCS components. Finally, the utilization factor of the MARK III Flex CCS was evaluated using sloshing loads obtained from the 174K LNG carrier model tests, thereby validating the practicality and reliability of the proposed methodology. The proposed method quantitatively accounts for the structural nonlinear response of the MARK III Flex CCS to sloshing loads while considering hull stiffness, thereby balancing prediction accuracy and engineering practicality for practical applications.
