Abstract
In recent years, studies for the development of cruise shipbuilding and design industry is known to be performed by many countries. It is obvious that cruise ships should be equipped with features that facilitate the mobility of the crew in different sea states by providing passenger comfort in long cruise conditions. At this point, cruise ships which require great cost and experience should be evaluated from different perspectives. In this study, the selection of stabilizer system which directly affects many criteria such as comfort, safety and speed in cruise ships is discussed. Stabilizer system alternatives and the criteria determined for these alternatives have been established by literature review. Extension of TOPSIS method with interval-valued spherical fuzzy sets proposed to determine the most effective stabilizing system alternative for cruise ships. The results obtained indicate the Activated fins as the most effective alternative.
