Optimizing the Seakeeping Performance of Ship Hull Forms Using Genetic Algorithm [PDF]
TransNav, 2014 Hull form optimization from a hydrodynamic performance point of view is an important aspect of ship design. This study presents a computational method to estimate the ship seakeeping in regular head wave. In the optimization process the Genetic Algorithm

Vertical Hull Vibration by a Main Engine in Regular Head Waves
Journal of the Society of Naval Architects of Japan, 1987 This paper discusses characteristics of vertical hull vibration excited by a main engine in regular head waves. The ship structure is modelled as a Euler beam to have added mass, which is derived from calculated results of ship motion by using the ordinary strip theory.

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

A numerical investigation on the nominal wake of KVLCC2 model ship in regular head waves
International Journal of Naval Architecture and Ocean Engineering, 2020 Analysis: of the propulsion performance considering ship motion in waves is an important factor for the efficient operation of a ship. The interaction between the propeller and the free surface due to the ship motion in waves has a significant influence ...
