The nonlinear dynamic analysis of a tension leg platform is carried out by using nonlinear spectral analysis in this paper. The nonlinear response spectrum is obtained by introducing Hermite polynomial. The study indicates that it is possible to solve nonlinear vibration problems by using spectral analysis directly. It is not necessary to linearize the nonlinear terms in this method so that the errors introduced by linearization can be eliminated. This method will provide a convenient and accurate tool for solving nonlinear random vibration problems.
