Paper presented at the The 29th International Ocean and Polar Engineering Conference, June 16–21, 2019
Paper Number: ISOPE-I-19-032
... ABSTRACT The Wigley hull is considered as the initial ship, which can be globally deformed by shifting method and locally deformed by RBF (Radial Basis Function) method to generate a bulbous bow. Two optimization cases are given. In case 1, only shifting method is used, while in case 2...

... ABSTRACT This paper provides a time-domain simulation on green water of a Wigley hull sailing in regular head waves. To predict the strong nonlinear phenomenon of green water, a numerical model is established by utilizing FINE/Marine, a multiphase-flow software based on free-surface capturing...

A dissipative 3D Green function is derived where the Laplace equation, free surface condition and the radiation condition are transformed using a Fourier transform to get the Havelock-Lunde formula of the double integral. Thin ship theory is adopted to determine the wave pattern behind a Wigley hull...
