This paper deals with the development of a complete second-order theory for the evaluation of motions and loads of arbitrarily shaped 3D bodies in waves at finite water depth. The developed second-order potential theory leads to the solution of integral equations for the evaluation of second-order potentials and corresponding second-order pressures, forces, motions, etc. The developed algorithm for the treatment of the second-order inhomogeneity of the free-surface boundary condition allows the application of the related computer program to bodies of arbitrary shape, in contrast to previous theories applicable only to axisymmetric bodies. The paper includes typical numerical results for the second-order motions and loads for various bodies of both axisymmetric and nonaxisymmetric shape. © 1993. (EN)
