Terminal Römorkörlerinin Ana Makine Hatalarının Çevresel, Ekonomik ve Güvenlik Etkilerinin Bulanık AHP ve Bulanık TOPSIS yöntemi ile Değerlendirilmesi

Abstract

Deniz terminalleri küresel ham petrol tedarikinde önemli bir yer tutmaktadır. Deniz terminaller için en önemli bileşenlerden biri römorkörlerdir. Römorkörlerin güvenli ve sorunsuz çalışması, kritik öneme sahiptir. Bu çalışmada ham petrol terminalinde görev yapan bir römorkör için ana makine hatalarının güvenlik, çevresel ve ekonomik etkileri birlikte ele alınarak risk analizi gerçekleştirilmiştir. Bu kapsamda ilk olarak bulanık AHP metoduyla güvenlik, çevresel ve ekonomik kriterlerinin önem dereceleri belirlenmiştir. Daha sonra güvenlik, çevresel ve ekonomik etkiler birlikte düşünülerek bulanık TOPSIS yöntemi ile belirlenen 26 hata modu için risk sıralaması yapılmıştır. Sonuçlar, deniz terminal için en önemli risk parametresinin güvenlik olduğunu göstermiş ve bunu ekonomik ve çevresel parametreler izlemiştir. Sonra, risk parametrelerin önem ağırlıkları dikkate alınarak bulanık TOPSIS ile hata modlarının risk sıralaması yapılmış ve en riskli hatanın yakıt hattı sızıntısı olduğu belirlenmiştir. Bunu sırasıyla hava filtresi tıkanıklığı ve egzoz sisteminde geri basınç olması izlemiştir. Bu çalışma ham petrol terminalinde faaliyet gösteren römorkörler için kapsamlı bir risk değerlendirmesi sunmakta olup ilgili paydaşlar için önemli bir rehber olması beklenmektedir.

Evaluation of Environmental, Economic and Safety Impacts of Main Engine Failures of Terminal Tugboats by Fuzzy AHP and Fuzzy TOPSIS Methods

Abstract

Marine terminals have an important place in the global crude oil supply. Tugboats are one of the major components for marine terminals. Safe and trouble-free operation of tugboats is of critical importance. In this study, a risk analysis was performed by considering the safety, environmental and economic effects of main engine failures for a tugboat operating in a crude oil terminal. In this context, firstly, the importance levels of safety, environmental and economic criteria were determined with the fuzzy AHP method. Then, the risk ranking was carried out for 26 failure modes with the fuzzy TOPSIS method by considering the safety, environmental and economic effects together. The results showed that the most important risk parameter for the marine terminal was safety, followed by economic and environmental parameters. Then, the risk ranking of failure modes was performed with the fuzzy TOPSIS by considering the importance weights of the risk parameter, and the riskiest failure was determined as fuel line leakage. This was followed by air filter blockage and back pressure in the exhaust system, respectively. This study provides a comprehensive risk assessment for tugboats operating in a crude oil terminal and is expected to be an important guide for the relevant stakeholders.
