【摘要】 围绕液舱晃荡效应对FPSO运动的影响展开分析,基于势流理论和三维频域格林函数法分别对船体运动与液舱晃荡进行分析,建立并求解了耦合运动方程,得到了对应的水动力运动系数。以某FPSO在波浪中的运动响应为例,采用水动力分析程序对考虑液舱晃荡和不考虑晃荡两种情况进行了对比计算,分析了液舱横向分舱布置和液舱装载率的变化对液舱晃荡效应的影响,为FPSO的设计与运营提供了参考。更多还原

【Abstract】 Focusing on the analysis of sloshing effect on FPSO motion, coupling analysis of tank sloshing and ship motions is carried out in frequency domain based on the Potential Flow Theory and Green Function, with the relative hydrodynamic coefficients obtained. By taking a certain FPSO as an example, the motion responses of FPSO in the situations of the sloshing considered or not considered are calculated and compared by using the hydrodynamic program, the influence of transverse subdivision arrangement and tank loading rate on sloshing effect is assessed.更多还原
