Hull Form Parameterization Technique with Local and Global Optimization Algorithms
The paper is presented on the development of a designer friendly hull form parameterization and its coupling with a local and a global optimization algorithm: the well known Sequential Quadratic Programming (SQP) and the more recent evolutionary Particle Swarm Optimization (PSO). These two algorithms are representative of classes with rather opposite characteristics (derivative–based and deriva...
متن کاملHull Form Optimization for Monohull Ships
A study was carried out to investigate methods and to determine the "optimum" hull form for monohull ships, based upon several weighted criteria. The main product of this study is a hull form optimization program. Propulsion power minimization is the primary focus of the program, although simplified. seakeeping and weight/cost issues can also be studied with the existing program. The program us...
متن کاملShip Hull Form Optimization using Artificial Bee Colony Algorithm
In this paper, artificial bee colony (ABC) algorithms are introduced to optimize ship hull forms for reduced drag. Two versions of ABC algorithm are used: one is the basic ABC algorithm, and the other is an improved artificial bee colony (IABC) algorithm. A recently developed fast flow solver based on the Neumann-Michell theory is used to evaluate the drag of the ship in the optimization proces...
متن کاملHull-form optimization in calm and rough water
The paper presents a formal methodology for the hull form optimization in calm and rough water using wash waves and selected dynamic responses, respectively. Parametric hull form modeling is used to generate the variant hull forms with some of the form parameters modified, which are evaluated in the optimization scheme based on evolutionary strategies. Rankine-source panel method and strip theo...
متن کاملHull Form Optimization for Early Stage Ship Design
Shape optimization is a growing field of interest in many areas of academic research, marine design, and manufacturing. As part of the CREATE Ships Hydromechanics Product, an effort is underway to develop a computational tool set and process framework that can aid the ship designer in making informed decisions regarding the influence of the planned hull shape on its hydrodynamic characteristics...
