Optimizing the Seakeeping Performance of Ship Hull Forms Using Genetic Algorithm [PDF]

open access: yesTransNav, 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

CFD Simulation on Workability of a Seaweed Harvesting Boat Due to Wake-Wash

open access: yesJournal of Marine Science and Engineering, 2020
In the present study, a 2-ton class seaweed harvesting boat was optimized by employing a W-shape hull form to reduce roll motion due to wake-wash from passing boats.

A Novel Hull Girder Design Methodology for Prediction of the Longitudinal Structural Strength of Ships

open access: yesJournal of Marine Science and Engineering
The ship hull girder model has been widely adopted in ship mechanics research such as small-scale and large-scale hydroelastic ship model experiments. Current design methods cannot seriously meet the structural rigidity requirement, and the distinction ...

Ship resistance performances assessment for a containership

open access: yesAnnals of "Dunărea de Jos" University of Galaţi: Fascicle XI Shipbuilding, 2021
The present work is focused on ship resistance performances assessment for a given capacity containership. Starting from the main dimensions of a parent ship, other ten hull forms have been generated using DELFTship free program.

Designing Ship Hull Forms Using Generative Adversarial Networks

open access: yesAI
We proposed a GAN-based method to generate a ship hull form. Unlike mathematical hull forms that require geometrical parameters to generate ship hull forms, the proposed method requires desirable ship performance parameters, i.e., the drag coefficient ...

Algebraic ship hull surfaces with a main frame from three plane curves in coordinate planes

open access: yesRUDN Journal of Engineering Research, 2022
One of the important problems of naval architects and designers is a choice of rational ship hull shape. A choice of ship hull form is based often on empirical formulae or on designers’ intuition.
