Numerical Investigation of Effect of Changing Dimensions on DDG Seakeeping Performance

In this article we have discussed seakeeping different body types. As we know seakeeping ability of a vessel or offshore structure to the desired buoyancy is such that if a vessel or floating structures، seakeeping good، bad sea conditions can also have acceptable performance. Numerical Investigation movements with heave and pitch of three type hull of Wigley، Series 60 and DDG 51 floating in front of the regular wave and validation of numerical results are compared with experimental results to predict seakeeping floating ship in effect Maxsurf Ratios software deals have. It should be noted that the shape and size of ship movements of the body، but the results of this study cannot be used in similar cases.
