Numerical study of trimaran wave load based on time-domain Rankine method

Due to the complex fluid interference between outrigger and main hull, it is difficult predict trimaran load fluctuation accurately in different marine environments. Therefore, a time-domain Rankine method developed improve accuracy of prediction. This successfully adds nonlinear components simulation by taking into account factors such as instantaneous hull wetted surface, steady ship waves, green wave slamming. Additionally, growth slamming also observed at wet deck, with increasing speeds heights. Finally, relatively smaller errors are confirmed comparison values from model test linear prediction method. Furthermore, weakly considered be more suitable for under harsh environment.
