Investigation of Ballast Water Treatment System Selection Parameters and Cost Analysis: Tanker Ship Application

Öz

Ballast water is taken into the tanks of ships to ensure stability during voyages, but it also contributes to the spread of invasive species, causing ecological and economic damage. To address this problem, the International Convention for the Control and Management of Ships' Ballast Water and Sediments was introduced in 2017, which sets D2 standards to regulate the number and size of organisms in ballast water. The aim of this study is to identify the key factors in the selection of a ballast water treatment system and to calculate the costs associated with a tanker ship. Through a literature review, important parameters affecting the selection of ballast water treatment systems were identified. Based on these parameters, the most suitable system for a chemical tanker was determined and a cost analysis was performed. The study specifically focused on the hydrocyclone UV ballast water treatment system and evaluated both installation and operating costs. The findings show that the hydrocyclone UV system is the most suitable option for chemical tankers in accordance with international regulations. The research emphasises that the initial installation cost as well as operating costs should be considered in the decision-making process. The results provide valuable information to shipowners and operators in selecting an efficient and cost-effective ballast water treatment system that meets regulatory requirements.

Balast Suyu Arıtma Sistemi Seçim Parametrelerinin İncelenmesi ve Maliyet Analizi: Tanker Gemisi Uygulaması

Öz

Balast suyu, seferler sırasında dengeyi sağlamak için gemilerin tanklarına alınır, ancak aynı zamanda istilacı türlerin yayılmasına katkıda bulunarak ekolojik ve ekonomik zarara neden olur. Bu sorunu ele almak için, balast suyundaki organizmaların sayısını ve boyutunu düzenlemek için D2 standartlarını belirleyen Gemilerin Balast Suyu ve Sedimanlarının Kontrolü ve Yönetimi için Uluslararası Sözleşme 2017 yılında uygulamaya konmuştur. Bu çalışmanın amacı, bir balast suyu arıtma sisteminin seçimindeki temel faktörleri belirlemek ve bir tanker gemisi ile ilgili maliyetleri hesaplamaktır. Literatür taraması yoluyla, balast suyu arıtma sistemlerinin seçimini etkileyen önemli parametreler belirlenmiştir. Bu parametrelere dayanarak, bir kimyasal tanker için en uygun sistem belirlenmiş ve bir maliyet analizi yapılmıştır. Çalışma özellikle hidrosiklon UV balast suyu arıtma sistemine odaklanmış ve hem kurulum hem de işletme maliyetlerini değerlendirmiştir. Bulgular, hidrosiklon UV sisteminin kimyasal tankerler için uluslararası yönetmeliklere uygun en uygun seçenek olduğunu göstermektedir. Araştırma, karar verme sürecinde ilk kurulum maliyetinin yanı sıra işletme giderlerinin de göz önünde bulundurulması gerektiğini vurgulamaktadır. Sonuçlar, mevzuat gerekliliklerini karşılayan verimli ve uygun maliyetli bir balast suyu arıtma sistemi seçme konusunda armatörlere ve operatörlere değerli bilgiler sağlamaktadır.
