OPTIMISATION OF HULL FORM OF OCEAN-GOING TRAWLER

Automatic Hull Form Optimisation towards Lower Resistance and Wash Using Artificial Intelligence

This paper describes the procedure developed at MARINTEK for the automatic optimisation of hull lines to reduce the ship resistance as well as the wake wash generated by a ship within the given constraints. The methodology, developed computer programs and used constraints are described. The methodology is exercised using lines of a fast ship. A numerical comparison is performed between the resi...

Convex hull manipulation based control performance optimisation

This paper deals with the topic of qLPV state-space model based control design in which LMIs are used to optimize the multi-objective control performance. In this paper we investigate how the manipulation convex hull of the polytopic model influences the control performance which is derived by LMIs. We examine these influences through the control design of the two dimensional aeroelastic system...

Hull 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...

CFD Analysis on the Bare Hull Form of Submarines for Minimizing the Resistance

In this paper, a CFD analysis on the bare hull form of submarines or torpedoes for minimizing the resistance is represented. There are several parameters in submarine form design which the most important parameter is resistance. All operational characteristics of submarines are related to the resistance, related required power and then, underwater speed and range. Other parameters are only ment...
