Abstract

The modified Bales-Wijngaarden seakeeping index has been used for the comparison of seakeeping performance of diverse hulls. The hull shape family has been generated and seakeeping calculations were conducted for this family. The results of the calculations were transformed into modified Bales- Wijngaarden index form. The influence of hull geometry on the seakeeping index has been presented in the form of threedimensional diagram as well as the multiple regression equations. 1 Introduction Within the framework of design methodology elaborated for certain types of offshore positioned vessels the need had appeared to create the means for the comparison of geometrically different hulls under various aspects. As the part of this methodology the met
