摘要
通过时域数值计算和模型试验分析FPSO在浅水非共线风浪流海况作用下的运动性能与舷侧甲板上浪情况。结果表明,艏摇角对于FPSO的摇荡影响显著,斜向迎浪,船舯附近比船艏和船艉处更容易发生甲板上浪;相同水深时,有义波较高海况下FPSO的横摇和纵摇运动响应反而较低,但上浪现象较严重;相同海况下,水深较浅时运动较小,符合浅水效应规律,但此时舷侧甲板上浪更为严重。
Through time domain numerical simulations and model tests to analyze motions and green water of FPSO in shallow water with non-collinear environments.It is shown that the effect of yawing angle on motions of FPSO is considerable and green water occurs more frequently around the midship than bow and stern.When the same depth,the roll and pitch motions are lower in the higher sea but green water occurs seriously.When the same sea condition,the motions are lower in the shallower but green water occurs more seriously.
