Kimyasal Tankerlerde Zaman Süreli Kiralamaya Göre Dedveyt Tonaj Aralığının Belirlenmesi
Determination of Dedweight Tonnage Range According to Time Charter in Chemical Tankers

Summary/Abstract: International transportation is carried out with many different models. The mode of transportation with the largest proportion of these models is known as the Seaway. There are different types of ships in maritime transport. The different tonnage diversity and structural differences of tanker ships, among these ship types, affect both cargo carrying areas and different cargoes. Chemical tanker ships are extensively utilized in the maritime industry, emerging as one of the foremost vessel types. The utilization of chemical tankers in domestic and international waters witnesses a steady rise. Rather than constructing and owning new ships, maritime enterprises and shipowners opt to lease actively operating vessels for a specific duration. This preference shift has underscored the significance of meticulous ship selection for transporting chemical cargoes, particularly considering tonnage. Various criteria and methodologies are employed to meticulously choose the most suitable chemical tankers for time charter contracts. Among these selection processes, extensive scrutiny of ship selection studies revealed that deadweight tonnage (DWT) stands as the most commonly employed criterion. For this reason, in this study, it is aimed to reveal the most ideal ship based on the chemical tanker selection, especially on the basis of their tonnage. With the ELECTRE method of chemical tanker type ships in 5 different tonnage ranges, the most ideal ship tonnage for time chartering was determined based on 5 important criteria determined by the experts working actively in the maritime field. According to the results of the analysis, the most ideal tonnage range was chosen as 1-10.000 DWT. The second tonnage preference was determined as 15.001-20.000 DWT. As a result of the study, reference tonnage ranges have been proposed to maritime companies and charterers that will make long-term charters.
