Chemical tanker ships are one of the most used types of tanker ships in the maritime market. The use of chemical tankers in national and international waters is increasing day by day. Maritime businesses and shipowners prefer to lease the ships that are active in the market for some time instead of building and owning new ships. Due to the increase in preferences, it has been seen that it is an important issue to determine the selection of ships to carry this type of chemical cargo in different criteria. Many different criteria and methods are used to choose the most ideal of these chemical tankers based on the temporal charter of the maritime enterprises. In this regard, this study is aimed to determine the criteria that should be used for the selection of chemical tankers and to group these criteria. For this purpose, a survey study was conducted. 85 different chemical tanker selection criteria and the best 23 distinguishing criteria were determined using the Delphi method. It is envisaged that these 23 criteria will allow the authorized personnel of the company to choose the most ideal alternative chemical tanker.
