Multidisciplinary Design Optimization of Ship Hull Forms Using Metamodels
Volume 5: 37th Design Automation Conference, Parts A and B, 2011Multidisciplinary optimization is a highly iterative process that requires a large number of function evaluations to evaluate objective functions and constraints. Metamodels for computationally expensive functions or simulations can be employed in the multidisciplinary optimization instead of the actual solvers resulting in significant computational ...

Multi-Objective Optimization for Ship Hull Form Design
2009Hydrodynamic optimization is an important aspect of ship design. The aim of this dissertation is to develop a computational fluid dynamics (CFD)-based computational tool for the hydrodynamic design of ship hull forms. The main components of this hull-form hydrodynamic optimization tool consist of a hull geometry modeling and modification module, an ...

Optimal hull forms from analysis of seakeeping data
1990This report describes an attempt to identify the optimum design for seakeeping from a parametric series of hull forms. The predicted performance of the hulls, as a function of design, speed and the non-dimensional zero crossing period for sea state, was stored as a vector.

An optimization approach for fairing of ship hull forms
Ocean Engineering, 2006This paper presents a numerical fairing procedure to be used at the preliminary design stage to create high-quality ship hull form geometry. The procedure is based on a variational optimization approach in which a fairness measure related to the surface curvature is the objective function to be minimized subject to a set of geometric constraints to ...

Numerical optimization of a hull form with bulbous bow
2011A genetic algorithm technique has been applied to deal with the hydrodynamic optimization of a hull form with bulbous bow. A non interactive procedure has been developed to minimize the objective function, related to the flow past a ship moving with steady forward speed in calm water. The paper discusses the application of the genetic algorithm coupled
