Abstract
Abstract This work analyzed the behavior of a helicopter that needed to land in water and compared the results from two methods, Boundary Element Method (BEM) and Computational Fluid Dynamics (CFD), in terms of their predictions of the helicopter’s response to waves. The study concluded that while BEM can provide quick results for estimating loads on the floaters in not-so-rough wave conditions, it cannot predict capsizing and should be used with caution. On the other hand, CFD can provide accurate results, but it has a higher computational cost. The results of the study showed that BEM and CFD produce similar results in terms of the natural period of roll and pitch, and that the time-domain simulation of 600 seconds using BEM can be used to estimate cabin acceleration. However, CFD simulations are necessary to check for capsize or water inside the cabin in future works.
