Abstract

Roll motion stabilization systems are preferred on many types of ships to ensure crew efficiency and cargo safety. In particular, since large roll motions increase the effects of fatigue and vomiting at sea, they adversely affect the mobility of travelling or working people on board. With this situation, when the navigation conditions and operational characteristics for different ship types are taken into consideration, the need for roll stabilizing system will arise. Roll motion stabilization systems are preferred by considering various criteria when chosen for different ship types. In this study, it is aimed to create a systematic procedure for selecting the roll stabilization system in the preliminary design for ships. In order to reduce the roll motion of a fishing boat, roll stabilizing system selection criteria and alternatives have been determined based on expert opinions and literature review. The weightings regarding criterion-alternative relationship are decided by three expert groups of Naval Architecture and Marine Engineer, and the best alternative is determined through hybrid firzzy AHP-TOPSIS structure.
