In order to analyze the dynamic of a turret moored tanker, a perturbation method was used to predict the RAO and the spectra of motion and mooring line tension under the irregular wave condition. The calculation results were compared with the corresponding test results. In the test, the wave heading is 180°, the wave spectrum are P M spectrum and a spectrum with flat and broad form called white noise. In the theoretical calculation, the slow oscillation damping coefficient of tanker was obtained by a test in irregular waves where the mooring system is substituted by a spring system with the similar stiffness. From the comparison, it was found that the theoretical results conform well to the test results. The second order perturbation method can be used to analyze the dynamic response of a turret moored tanker.
