PRACTICAL SEAKEEPING FOR DESIGN: AN OPTIMISED APPROACH

Kadir Sarıöz, G E Hearn, Bill Hills

Open publisher page 3 citations

Abstract

The ITTC adopted container ship form, designated S175, is investigated for seakeeping optimisation, subject to automatic satisfaction of IMO stability regulations and due consideration of the calm water resistance characteristics. Different objective functions are used in the optimisation, and the relative importance of improvements due to principal dimension variations and ship form parameter changes reported. Operability of the alternative designs in different load conditions are discussed. The paper concentrates on the application of the developed techniques rather than the associated mathematical detail. The procedure developed provides a new fully automated optimisation technique suitable for design office application.
