병렬계류된 선박의 감쇠력에 관한 실험연구

Abstract

Low-frequency damping characteristics of side-by-side moored LNG-FPSO and LNGC are investigated through a series of free decay model tests in calm water and under wind load condition. It is shown that low frequency damping of LNGC changes dramatically, sway damping increases more than six times for 4m distance condition while it decreases by 30% for 20m distance compared with a single LNGC case. Simulation using the experimental data enhances the results, which demonstrates the necessity of experimental low-frequency damping coefficients for simulation of side-by-side vessels motion behavior.
