A GENERALISED APPROACH TO SEAKEEPING EVALUATION IN INITIAL STAGES OF SHIP DESIGN

Seakeeping qualities characterise ship behaviour for the greater part of its service life. However, the author says, the optimisation of seakeeping was regarded as a secondary element in the choice of a minimum resistance form and in most cases was considered last. In this paper a complex seakeeping evaluation procedure is proposed for application to the problem of ship form optimisation, based on the following main prerequisites; i) that the standard optimisation function composed of calm water performance criteria should be smooth so that the optimum solution allows a fairly free choice of main design parameters; ii) the seakeeping characteristics are not too sensitive to small changes in the hull form, both general and local; iii) no ship form description form is required for the computational evaluation of seakeeping; and iv) the seakeeping qualities can be made dependent on a particular number of general geometric characteristics of the hull form.
