Guo et al. (2012) have investigated sinkage and trim of KVLCC2 container ship. They showed that sinkage and trim values of KVLCC2 are very small. For this reason in this study model fixed from its floating position and it is not free to sinkage and trim, their effects on ship resistance are neglected. During the ship motion analysis, the pitching and heaving motions are free, and other motions are not permitted. Both ship motion and ship resistance simulation, the effect of the wind is not taken into account. Three different seakeeping simulation conditions are given in Table 2. U is the ship speed, f is the wave frequency, fe is the encounter frequency, λ is the wave length and ζ is the wave amplitude.
