Exploring Research Trends on Climate Change: Insights into Port Resilience and Sustainability

TÜRKİSTANLI TAHA TALİP | ÖZİSPA NERGİS | TUĞDEMİR KÖK GÖKÇE | ÖZDEMİR ÜNAL | PEHLİVAN DAVUT

Ports play a critical role in global trade, yet they are both contributors to and recipients of climate change. This study conducts a bibliometric analysis to examine the relationship between climate change and port operations, identifying key themes, methodological approaches, and research gaps within the literature, including the need for standardized vulnerability assessments, policy-driven adaptation strategies, and a more integrated, cross-regional approach to port resilience. A bibliometric analysis was performed using peer-reviewed journal articles indexed in the Web of Science. The study employed keyword-based searches, document screening, and bibliometric techniques such as publication trends, keyword co-occurrence analysis, citation impact evaluation, and research clustering. Stu...

Analysing occupational injuries onboard in Türkiye: human factors and under-reporting issues

Türkistanlı, Taha Talip | Pehlivan, Davut

Background: Maritime transportation remains one of the most hazardous industries globally, with work-related incidents posing significant risks. Material and Method: This research investigates onboard occupational injuries in the Turkish maritime sector, focusing on cases between 2013 and 2024. The study analyzes onboard injuries using the Human Factors Analysis and Classification System and Multiple Correspondence Analysis. Results: The study reveals that human error, inadequate supervision and insufficient organisational processes are primary contributors, particularly in dry bulk vessel operations. A lack of adequate rescue operations is noted, leading to high fatality rates. Furthermore, the analysis identifies a significant issue of under-reporting, especially in less severe eve...

Eco‐efficiency evaluation of diesel engines fueled with diesel–biodiesel–ammonia blends using data envelopment analysis

Okumuş, Fatih | Pehlivan, Davut

An experimental investigation was conducted to evaluate the emission and performance characteristics of a single‐cylinder diesel engine fueled with various combinations of diesel, biodiesel, and ammonia. The test matrix covered 4 biodiesel levels (0%, 20%, 40%, and 100%) and 4 ammonia energy fractions (0%, 20%, 40%, and 60%) across three engine loads (50%, 75%, and 100%), ensuring a comprehensive exploration of dual, and triple‐fuel strategies. A total of 48 distinct fuel scenarios were tested under controlled conditions. The relative efficiency of each configuration was assessed using input‐oriented Constant Returns to Scale Data Envelopment Analysis (CCR‐DEA), where engine efficiency was treated as the desirable output, and CO, CO2, HC, and NOx emissions were considered undesirable outpu...
