| 摘 要： | 针对水深对浅水超大型FPSO波浪诱导载荷的影响,在国际船级社协会(IACS)纵向强度标准的基础上,探讨了不同水深波浪诱导弯矩的长期预报值与波浪弯矩设计值的关系.开发了基于有限水深复合格林函数波浪诱导弯矩数值计算程序模块,对一艘300K DWT FPSO在不同水深海况下的波浪诱导载荷进行了长期预报.研究结果表明,水深对波浪弯矩设计值的影响很大.

| Abstract: | According to the effects of water depth on the wave-induced vertical bending moment of a very large FPSO in shallow water,the relationship between the long-term prediction value of variable water-depth and the design value of the wave-induced bending moment is studied based on the IACS UR S11.The restricted water depth composite green function is employed to develop a program for the computation of the wave-induced moment of the FPSO in shallow water.The long-term prediction value of wave-induced bending moment of a 300K DWT FPSO was calculated.The calculation results show that the water depth has an evident effect on the ratio of the long-term prediction value to the design value of the wave-induced bending moment. |
