摘　　要：随着浅水超大型FPSO在渤海湾海域的广泛应用,水深对波浪诱导载荷的影响成为新的热点课题。文章推导了有限水深复合格林函数,结合三维势流理论用于计算浅水FPSO的水动力特性。采用开发的程序计算了一艘浅水300K DWT FPSO的脉动压力。计算结果表明浅水脉动压力与深水脉动压力的分布规律明显不同。With the wide use of very large FPSO in shallow water of Bohai Bay, a new subject concerning the effects of water depth on wave-induced loads response of FPSO appears.In this paper, the composite green function for the restricted water depth is employed to develop a program for the computation of the hydrodynamic coefficients of the FPSO in shallow water based on three-dimensional theory.The oscillating pressure of a 300K DWT FPSO was calculated.The calculation results show that the oscillating pressure in shallow water is different from that in deep water.
