Çıkarma Gemilerinin Enerji Verimliliği Dizayn İndeksi (EEDI) Performansının Analizi

Abstract

Gemi endüstrisi, dünya ticaretinin belkemiğidir ve enerji verimliliği bu endüstrinin temel bir önceliğidir. Deniz taşımacılığı, küresel enerji tüketiminin önemli bir kısmını temsil ederken, aynı zamanda sera gazı emisyonlarının da önemli bir kaynağıdır. Bu nedenle, gemi tasarımı ve işletmesinde enerji verimliliğini arttırmak ekonomik ve çevresel açıdan kritiktir. Uluslararası Denizcilik Örgütü (IMO), gemilerin enerji verimliliğini değerlendirmek ve geliştirmek için çeşitli önlemler almıştır. Bu önlemler arasında, IMO tarafından ortaya konulan enerji verimliliği dizayn indeksi (EEDI), gemilerin enerji etkinliğini değerlendirmek ve karşılaştırmak için kullanılan önemli bir araçtır. EEDI, gemi inşaatının erken aşamalarında tasarım ve mühendislik kararlarını yönlendirerek ve optimize ederek enerji verimliliğini artırmayı amaçlar. Bu çalışmada, IMO'nun EEDI hesaplama yöntemi kullanılarak askeri gemilerin verimlilikleri değerlendirilmiş ve referans değerlerle karşılaştırılmıştır. Farklı boyutlarda ve makine güçlerine sahip birden fazla gemi üzerinde yapılan çalışmada, örnek bir gemi için hesaplama yöntemi gösterilerek tüm gemilere uygulanmıştır. IMO tarafından farklı ticaret gemi tipleri için belirlenen referans verimlilik değerleri hesaplama yöntemi de paylaşılmıştır. Çalışmada, askeri çıkarma gemi tipine en çok benzeyen Roll on-Roll off (Ro-Ro) tipi kargo ticaret gemisi kullanılarak hesaplama yapılmıştır. Sonuçlar gerçek EEDI değerlerinin referans verimlilik değerlerinden yüksek olduğunu göstermiştir. Bunun nedeni, askeri gemilerin enerji verimliliğinden çok operasyonel kabiliyetlerine odaklanılmasından kaynaklanmaktadır. Ancak, enerji tüketiminde yapılacak iyileştirmelerin stratejik avantajlar sağlayabileceği öngörülmektedir. Çalışma, askeri gemilerin enerji verimliliğini artırmak için optimize edilebileceklerini ve bu iyileştirmelerin operasyonel kabiliyeti ileri düzeye taşıyabileceğini vurgulamaktadır. Gelecekte yapılacak optimizasyonlarla tasarruf edilen enerjinin farklı alanlarda kullanılarak operasyonel kabiliyetin geliştirilebileceği öngörülmektedir.

Analyzing the Energy Efficiency Design Index (EEDI) Performance of Landing Ships

Abstract

The shipping industry is the backbone of world trade and energy efficiency is a key priority for this industry. While maritime transport represents a significant portion of global energy consumption, it is also a major source of greenhouse gas emissions. Therefore, improving energy efficiency in ship design and operation is economically and environmentally critical. The International Maritime Organization (IMO) has taken several measures to assess and improve the energy efficiency of ships. Among these measures, the energy efficiency design index (EEDI) is an important tool used to evaluate and compare the energy efficiency of ships. EEDI aims to improve energy efficiency by guiding and optimizing design and engineering decisions in the early stages of shipbuilding. In this study, the efficiency of naval ships is evaluated and compared with reference values using IMO's EEDI calculation method. In the study, the calculation method is demonstrated for a sample ship and applied to all ships. The calculation method of reference efficiency values determined by IMO for different types of merchant ships is also shared. The calculation was performed using a Ro-Ro type cargo merchant ship, which is most similar to the military landing ship type. The results show that the actual EEDI values are higher than the reference efficiency values. This is due to the focus on the operational capabilities of military ships rather than their energy efficiency. However, it is predicted that improvements in energy consumption can provide strategic advantages. The study highlights that naval ships can be optimized to improve energy efficiency and that these improvements can enhance operational capability. It is foreseen that the energy saved by future optimizations can be used in different areas to improve operational capability.
