HYDRODYNAMIC DESIGN OF A FISHING VESSEL HULL FORM SUITABLE FOR THE BLACK SEA ENVIRONMENT

In this paper, a systematic hull form generation and a seakeeping analysis of the generated forms to determine the best hull form for the Black Sea environment is presented. The first part of the paper details seakeeping calculations based on the three dimensional source distribution technique and their validation with experimental measurements obtained with a model of a fishing vessel parent hull form. The second part of the paper explains the method used for generating 24 different hull forms from a parent form which is an existing design used in the Black Sea. The third part of the the paper describes the results of the seakeeping analysis applied to these different hull forms to obtain motion response characteristics, absolute vertical accelerations and relative motions in a design sea-state. A ranking procedure to select the best hull form using the results of seakeeping calculations is explained. In the final part of the paper the results of a multiple regression analysis to define the seakeeping rank as a function of the various design variables are illustrated.
