Hydrodynamic hull form optimization using parametric models [PDF]

open access: yesJournal of Marine Science and Technology, 2012
Hydrodynamic optimizations of ship hull forms have been carried out employing parametric curves generated by fairness-optimized B-Spline form parameter curves, labeled as F-Spline. Two functionalities of the parametric geometry models are used in the present study: a constrained transformation function to account for hull form variations and a ...

Bow hull-form optimization in waves of a 66,000 DWT bulk carrier

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2017
This paper uses optimization techniques to obtain bow hull form of a 66,000 DWT bulk carrier in calm water and in waves. Parametric modification functions of SAC and section shape of DLWL are used for hull form variation.
