摘　　要： 使用挪威船级社(DNV)的SESAM程序系统计算了不同水深时超大型浮式生产储油系统(FPSO)的运动与波浪载荷传递函数,并对船舯弯矩进行了长期预报.结果表明,在波长船长比为0.1～1.0内,随着水深的变浅,垂荡、纵摇和横摇运动幅值减小,船舯弯矩幅值增大,而且水越浅,船舯弯矩值增大也越明显. The SESAM program of DNV was used to calculate the transfer function of motion response and wave induced loads of a large floating production,storage and offloading (FPSO) in various water depths,and the corresponding long term prediction of mid-ship section vertical bending moment was also obtained.It shows that in the range of the ratio of wave length to ship length 0.1～1.0,with the decrease of the (water) depth,the wave frequency motions,such as heave,surge and roll,decrease and the mid-ship section (vertical) bending moment increases.In addition,in the ultra-shallow water the bending moment increases very evidently with the decrease of the water depth.
