Outline of Final Research Achievements

Because both FLNG and LNG carrier have large LNG cargo tanks, the sloshing in the tanks have an impact on motion of side-by-side moored two ships during LNG transfer operation at sea. In this study, including the sloshing effect, ship motion in the wave intended for FLNG and LNG carrier were estimated based on the panel method. In addition, model test which simulate the side-by-side mooring were carried out at Ocean Engineering Basin in National Maritime Research Institute (NMRI). Comparison of estimated results of the numerical calculation and measurement results of the model test clarified a characteristic of liquid behavior in the tank and the motion of side-by-side moored two ships.
