The development of a method for predicting statistical stability of a vessel in preliminary design

Abstract

The authors have developed a procedure for obtaining a workable method giving satisfactory accuracy in preliminary ship design for predicting the curve of statical stability of a vessel when only the principal dimensions and hull coefficients of the vessel are known. The stability data upon which the development is based was obtained by mechanically integrating a parent hull form from Taylor's Standard Series and expanding the resulting righting are data to cover a range of ship forms. The methods of data expansion were those suggested in the 1949 thesis by Church and Robinson entitled "The estimation of transverse statical stability from form coefficients and principal dimensions", but modified as considered desirable to improve accuracy and convenience of application.
