Abstract	This paper predicts resistance and propulsion performances in regular and irregular head waves of a 1800 TEU container ship. 'Calm-water tests' and 'resistance test in regular waves' have been performed. Methods applied are the LVM-W and the revised ITTC-78. Added propeller revolution, thrust, and torque in waves linearly increase as added resistance does. The relative contributions of added propulsion performances in waves have been evaluated using the logarithmic derivative. The spectral method in operating sea states has been applied. The response spectra of added propeller revolution, thrust, and torque show similar characteristics to those of added resistance. The FSEM, LVM-IR, ITTC78-IR, DPM, RTIM, QNM, and TNM are useful to predict added delivered power and propeller revolution in irregular waves when SS < 5. These differences between the DPM/RTIM/QNM/TNM and the Spectral(LVM-W) are dependent on the linearity of fitting line for overload factor. The TNM underpredicts added delivered power due to the lower wake fraction in waves.
