Seakeeping capabilities represent a crucial aspect of marine hydrodynamics research. Calculating the movements, amplitudes, and accelerations of the ships offers valuable support for assessing and forecasting their
safety and security parameters while the ships are in use. While experimental data on ship movements in consistent wave patterns are considered reliable, they also come with high impacting costs. This research is particularly designed to estimate the seakeeping performance by assessing the hydrodynamic response of a 192-meter-long container ship vessel in both regular and irregular waves. The present computational study is focused
on predicting the six degrees of freedom responses for a ship at zero speed for different heading angles. Using
the panel method within Maxsurf Motions software, RAOs for all degrees of freedom are obtained. In irregular
sea simulations, the ITTC spectrum is employed.
