hull form
A study on the preliminary ship design method using deterministic approach and probabilistic approach including hull form
      
This paper describes a preliminary ship design method using deterministic approach and probabilistic approach in the process of hull form design.
      
In the deterministic approach, an interdisciplinary ship design method integrates principal dimension decisions and hull form variations in the preliminary ship design stage.
      
Conversely, in sequential design, which is based on the traditional preliminary ship design process, hull form designs and principal dimension decisions are determined separately and sequentially.
      
Development of a hull form definition tool with a related knowledge-based advisory system
      
The development of a parametric hull form design system utilizing combined knowledge-based and objectoriented methodologies, approaches, and techniques is the major purpose of this research.
      
The advisory system includes a knowledge bases consisting of hull form databases, results of the statistical analysis of data, design parameter constraints, and expert knowledge acquired from designers, reference materials, and technical reports.
      
The typical characteristics of the flow field in the steady turning condition are revealed by the numerical simulation, and the mechanism of the relations between hull form, flow field, and hydrodynamic forces are clarified.
      
Systematic study on the hull form design and resistance prediction of displacement-type super-high-speed ships
      
Systematic theoretical and experimental studies were carried out to establish methods for hull form design, optimum dimension selection, and resistance estimation for displacement-type super-high-speed ships.
      
In this study, a theoretical hull form design method for displacement-type super-high-speed ships was first developed using the minimum resistance theory and a sectionally varying hull form equation.
      
Using an established hull form design method, a series of 60 hull forms were prepared with systematic variations of the most important design variables, and model tests were conducted for these ship models.
      
The results shown here provide valuable information for hull form design and the validation of viscous ship flow codes and of turbulence models.
      
The accuracy of WISDAM-X is examined by a comparison with experimental data from a container carrier hull form, and shows a fairly good agreement with respect to ship motion and added resistance.
      
Simulations were also conducted for a bow-form series of a medium-speed tanker to examine the effectiveness of the WISDAM-X method as a design tool for a hull form with a smaller resistance in waves.
      
Recent developments in research into ship hull optimization need a method to express ship hull form as precisely as possible with a small number of design parameters.
      
A computational method for improving hull form in shallow water with respect to wave resistance is presented.
      
This is linked to the optimization procedure of the sequential quadratic programming (SQP) technique, and an optimum hull form can be obtained through a series of iterations giving some design constraints.
      
An optimum hull form for a catamaran can be obtained through a series of iterative computations, subject to some design constraints.
