Özet

The influence of ship length, length to beam ratio, beam to draft ratio, prismatic coefficient, non-dimensional radius of gyration and Froude number upon significant amplitude of coupled heaving and pitching motions of trawler hull forms for six different sea states has been studied. For this purpose, 540 trawler hull forms have been generated from Doust trawler series to cover appropriate ranges of the design parameters. Seakeeping behavior of these forms has been studied by using an established ship motion computer program and regression models of significant seakeeping events have been derived. Through this study, it is believed that a method has been produced for the seakeeping evaluation of trawler forms during the early design stages, hence allowing for the design of safer and more seakindly trawler designs.
