ELEKTRİKLE ÇALIŞAN BİR FERİBOTUN ENERJİ SİSTEM ANALİZİ VE MODELLENMESİ

Abstract

Günümüzde, dünya ticaretinin yaklaşık %85’i denizyolu ile yapılmakta olup gemiler, ulaştırma, lojistik ve ticaretin vazgeçilmez unsurlarıdır. Ancak öte yandan, küresel sera gazı emisyonlarının yaklaşık %2.5'i gemilerden ve deniz taşımacılığı faaliyetlerinden kaynaklanmakta, emisyonların hava kalitesi ve insan sağlığına olumsuz etkileri bulunmaktadır. Bu durumu göz önünde bulunduran Uluslararası Denizcilik Örgütü, gemilerde fosil yakıt yerine yenilenebilir/alternatif enerji kaynaklarının kullanımını teşvik etmektedir. Ülkemizin 11. Kalkınma Planı’nda da kısa mesafeli araç ve yolcu taşımacılığında kullanılan gemilerin “tam elektrikli” hale dönüştürülmesi hedeflenmektedir. Bu çalışmada; Referans Enerji Sistemi yaklaşımı ve Long Range Energy Alternatives Planning System yazılımı kullanılarak, deniz ulaşımında kullanılan yeni nesil diesel elektrik tahrikli bir arabalı feribotun enerji sistem modellemesi ve analizi yapılmıştır. Çalışmanın sonucunda, feribotun enerji sisteminin hibrit konsepte dönüşüm senaryosu için teorik emisyon tahminleri de dahil olmak üzere feribotun enerji sistemine ilişkin analiz sonuçları sunulmuştur. Ayrıca feribotun enerji verimliliğinin arttırılmasına yönelik de bazı öneriler de sunulmuştur.

ENERGY SYSTEM ANALYSIS AND MODELING OF AN ELECTRIC POWERED FERRY

Abstract

Today, approximately 85% of world trade is carried out by sea and ships are indispensable elements of transportation, logistics and trade. But on the other hand, approximately 2.5% of global green gas emissions, which have adverse effects on air quality and public health, is originated from ships and maritime transportation activities. Considering this situation, the International Maritime Organization promotes the use of renewable/alternative energy sources on ships, rather than fossil fuels. In the 11st Development Plan of Republic of Turkey, it is also aimed to convert the ships used for vehicle and passenger transportation in a short distance into “all-electric” concept. In this study, energy system analysis and modelling of a new generation ferry with a diesel electric propulsion system, which is used for vehicle and passenger transportation, have been carried out by using the Reference Energy System approach and Longrange Energy Alternatives Planning System software. In conclusion of the study, results of analysis related to the ferry’s energy system, which also include theoretical emission estimates for conversion scenario of the ferry’s energy system into hybrid concept, have been presented. Additionally, some suggestions for increasing energy efficiency of the ferry have been presented as well.
