파랑 중 FSRU와 LNGC의 접안 문제에 관한 동적 시뮬레이션

Abstract

In this study, the berthing problem between a FSRU and a LNGC was investigated by using three different numerical methods including dynamic simulation. At first, frequency-domain diffraction computations were carried out to study hydrodynamic interaction between two floaters in the berthing operation. With various relative positions, the effect of gap resonance and sheltering effect were discussed based on the frequency-domain solution. As the second numerical method, time-domain simulation using convolution integrals was used to simulate the berthing problem. The simulation results were directly compared with the model test data. The third numerical approach is dynamic simulation combined with direct fluid solver.
