Computation of main dimensions and form coefficients in initial ship design

In order to reduce CO2 emissions aboard the ship, the IMO strategy imposes the decrease of the Energy Efficiency Design Index (EEDI). The generation and multi-criteria optimization of the body lines plan represent an important solution for EEDI reduction. In this context, the selection and checking...

description In order to reduce CO2 emissions aboard the ship, the IMO strategy imposes the decrease of the Energy Efficiency Design Index (EEDI). The generation and multi-criteria optimization of the body lines plan represent an important solution for EEDI reduction. In this context, the selection and checking of the ship’s main dimensions and form coefficients in the initial design stage will contribute to obtaining satisfactory hydrodynamic performance. This paper deals with some statistical relations used to calculate the main dimensions and form coefficients in the initial ship design stage. It also describes the new PHP-Ship Dimensions computer codes, developed in the Research Centre of the Faculty of Naval Architecture of “Dunarea de Jos” University of Galati. On the basis of this numerical instrument, the checking of the displacement equation may be performed. The students will use the computer program in order to increase their knowledge related to initial ship design activities.
