Objective In the design stage of a luxury cruise ship, in order to save costs, it is necessary to use the computational fluid dynamics (CFD) method to predict the seakeeping performance of the cruise ship under design.
Method The research object of this paper is a large luxury cruise ship. The self-developed ship hydrodynamics CFD solver naoe-FOAM-SJTU is used to simulate the seakeeping performance of the luxury cruise ship at model scale. The seakeeping simulation adopts the speed entrance input wave-making method, and predicts and summarizes the cruise movement under different wave heights and downwards.
Results The evaluation finds that the designed cruise ship model basically meets the requirements of ship comfort at maximum speed and wave heights of 0.062 5, 0.1 and 0.15 m, and meets the requirements of ship safety at the design speed, wave height of 0.225 m and heading sea conditions.
Conclusion Under the calculated working conditions, this cruise ship design conforms to the safety and comfort standards in the seakeeping evaluation standards of luxury cruise ships.
