Paper Title
Bulbous Bow Optimization of KCS in Terms of Partially Parametric Modeling

Abstract
One of the methods to develop more energy efficient and environmentally friendly ships is the optimization of the hull form during the design phase. Forms with lower resistance values can be obtained by locally optimizing regions that haveeffect on resistance after global optimization of the hull form.This paper focuses on the local optimization of the bulbous bow form of well-known KRISO Container Ship (KCS) using simulation-driven design methodology. For this purpose, CAESES, a parametric modelling and optimization software, is used to create variants of initial bulb form of KCS in terms of partially parametric modeling and to manage the whole CAD and CFD process.
