KONTEYNER GEMILERININ ELEKTRIK TAHRIK SISTEMLERININ ENERJI VERIMLILIĞININ İNCELENMESI

Öz

Deniz taşımacılığı, küresel ticaret için kritik öneme sahiptir ve yılda 10 milyar tondan fazla konteyner taşımaktadır. Dizel motorlar gibi geleneksel tahrik sistemleri yıllardır kullanılmaktadır, ancak artan çevresel etkiler nedeniyle Uluslararası Denizcilik Örgütü (IMO) alternatif çözümler için baskı yapmaktadır. 2019 yılında, konteyner gemileri dâhil uluslararası deniz taşımacılığı, küresel sera gazı emisyonlarının %2,1’ini oluşturmuştur. Bu çalışmanın amacı, dizel elektrik tahrik sisteminin verimliliğini artırmaktır. Bu tür alternatif çözümlerden birini değerlendirmek amacıyla, bu çalışma bir açık deniz konteyner gemisinin dizel-elektrik (DE) tahrik sistemini simüle ederek üç senaryo kapsamında yakıt tüketimini ve emisyonları değerlendirmiştir. Yük profili, geminin seyir verileri kullanılarak oluşturulmuş; simülasyon, jeneratörlerin maksimum yükte çalışmasını sağlayacak ve bataryaların güç dengesine katkıda bulunacağı yapılandırmalar geliştirmeyi hedeflemiştir. Liman veya kıyı bölgesinde çalışan gemilerle sınırlı önceki çalışmalardan farklı olarak, önerilen yaklaşım; batarya destekli işletme ve sıfır emisyonlu liman uyumunu da içeren üç farklı tahrik senaryosunu, bütüncül bir metodolojik yapı içerisinde değerlendirmektedir. Bu çalışmada konteyner gemi tipi, sık manevra yapması ve bu süreçlerde değişken makine yükleri altında çalışması nedeniyle seçilmiştir. Sonuçlar üç senaryoya göre sırasıyla yakıt tüketiminde 2,9 % , 5,3 % ve 10,38 % azalma olduğunu göstermektedir

EXAMINATION OF THE ENERGY EFFICIENCY OF CONTAINER SHIP ELECTRIC PROPULSION SYSTEMS

Öz

Maritime transport is crucial for global trade, transporting over 10 billion tons of containers annually. Conventional propulsion systems like diesel engines have been used for years, but the International Maritime Organization (IMO) is pushing for alternative solutions due to increasing environmental impacts. In 2019, international shipping, including container ships, accounted for 2.1% of global greenhouse gas emissions. The study aimed to improve the efficiency of the diesel electric propulsion system. To evaluate one such solution, this study simulated an offshore container ship’s diesel-electric (DE) propulsion system, assessing fuel consumption and emissions across three scenarios. The load profile was created using the ship’s navigation data, and the simulation aimed to build configurations for generators to run at maximum load and batteries to contribute to power balance. Unlike prior works limited to port or coastal vessels, the proposed approach evaluates three distinct propulsion scenarios, including battery-assisted operation and zero-emission port adaptation, within a unified methodological structure. This study selected the container ship type because it frequently performs maneuvering operations and operates under variable engine load conditions during these periods. The results of three scenarios indicate fuel consumption reductions of 2.9%, 5.3%, and 10.38% respectively
