Determining Port Wind Limiting Conditions for Safe Maneuvering and Berthing

ABSTRACT: This paper examines the influence of lateral wind forces on ferry operations within the port of Gazenica, situated on the Croatian Adriatic coast. Utilizing wind data collected from May 2017 to June 2024, the study identifies southeasterly (SE) winds as the most critical factor affecting ferry maneuverability due to their frequency and intensity. The research assesses wind-induced forces on three specific ferries—"Brac," "Ugljan," and "Juraj Dalmatinac"—comparing these forces against their maximum propulsion capabilities. Findings reveal that extreme SE wind conditions can surpass the thrust capacity of these vessels, elevating the risk of drifting and grounding, as illustrated by the grounding incident of the ferry "Cres". Consequently, the study highlights the necessity for advancements in ship design, propulsion systems, navigational aids, and port infrastructure to mitigate risks associated with high wind speeds. Implementing such measures is vital for ensuring the safety and operational reliability of maritime activities in the port of Gazenica and comparable settings.
