摘要：The seakeeping performance of a luxury cruise ship was evaluated during the concept design *** comparing numerical predictions based on 3-d linear potential flow theory in the frequency domain with the results of model tests, it was shown that the 3-d method predicted the seakeeping performance of the luxury cruise ship *** on the model, the seakeeping features of the luxury cruise ship were analyzed, and then the influence was seen of changes to the primary design parameters (center of gravity, inertial radius, etc.).Based on the results, suggestions were proposed to improve the choice of parameters for luxury cruise ships during the concept design *** should improve seakeeping performance.
