Abstract

This study aims to identify the risk factors affecting navigational safety in the Çanakkale Strait by analyzing failure and deficiency reports of vessels transiting the Strait in both southbound and northbound directions throughout 2024. The analysis examines failure types, vessel categories, flag States, and temporal distributions, followed by the identification of critical failures are identified, and a Ship-Type Based Failure Risk Index (STFRI) is developed to determine comparable risk levels among vessel types. The highest number of failures was observed in dry cargo and container vessels. In the flag State analysis, open registry countries Liberia, Panama, and the Marshall Islands exhibited the highest failure frequencies. In this context, Turkish-flagged vessels recorded a total of eight failures, indicating a relatively lower failure count compared to the top three open registry flags; however, the reported failures include critical cases primarily related to main engine and navigational equipment. These findings suggests that the Turkish-flagged fleet performs comparatively better position in terms of overall failure burden, while also highlighting the continued importance of maintenance, inspection, and training processes in preventing critical failures. Failure frequency peaked in January and declined to its lowest level in March. No significant correlation was found between failure severity and gross tonnage. Overall, the STFRI model indicates that dry cargo and container vessels constitute the highest-risk group in the Çanakkale Strait. This approach is considered to provide valuable contributions to safety policies, inspection prioritization, traffic management, and navigational safety in the Strait.

Özet

Bu çalışma, 2024 yılı boyunca Çanakkale Boğazı’ndan güney ve kuzey yönlü geçiş yapan gemilere ait arıza ve eksiklik bildirimlerini analiz ederek bölgedeki seyir güvenliği üzerindeki risk faktörlerini ortaya koymayı amaçlamaktadır. Çalışmada öncelikle arıza türleri, gemi tipleri, bayrak devletleri ve zaman dağılımları detaylı biçimde incelenmiş; ardından kritik arızalar tanımlanarak gemilerin karşılaştırılabilir risk seviyelerini belirlemek amacıyla Tip Bazlı Gemi Arıza Risk İndeksi (Ship-Type Based Failure Risk Index - STFRI) geliştirilmiştir. En yüksek arıza sayısı kuruyük ve konteyner gemilerinde görülmüştür. Bayrak devleti analizinde açık kayıt (open registry) ülkeleri olan Liberya, Panama ve Marshall Adaları en yüksek arıza frekansına sahiptir. Bu kapsamda Türkiye bayraklı gemiler, toplam 8 arıza ile ilk üçte yer alan açık kayıt bayraklarına kıyasla daha sınırlı bir arıza sayısı üretmekte; bununla birlikte, bildirilen arızalar arasında ana makine ve seyir cihazı odaklı kritik vakaların da bulunduğu görülmektedir. Bu durum, Türkiye bayraklı gemi filosunun genel arıza yükü açısından daha iyi bir konumda olduğunu ve kritik arızaların önlenmesi için bakım, denetim, eğitim süreçlerinin önemini koruduğunu ortaya koymaktadır. Ocak ayında arıza yoğunluğu zirvede iken, Mart ayında ise en düşük seviyeye gerilemektedir. Ayrıca arıza şiddeti ile grostonaj arasında belirgin bir korelasyon olmadığı tespit edilmiştir. Sonuç olarak, STFRI modeli kuruyük ve konteyner gemilerinin Çanakkale Boğazı’nda en yüksek risk grubunu oluşturduğunu göstermiş; bu yaklaşımın, güvenlik politikaları, denetim önceliklendirmesi ve Boğaz geçiş trafiğinin yönetimi ve seyir güvenliği açısından önemli katkılar sağlayabileceği değerlendirilmiştir.
