Relación de la hidrodinámica marina con el movimiento de buque atracado y su afección en la operatividad portuaria

Abstract

Incidents in ports can cause economic losses and reductions in security. Horizontal movements of docked vessels are associated with these problems, and infragravity waves can amplify them when they are in the same period range (25-150 s). The objective of this doctoral thesis is to optimize port operations by prioritizing safety, focusing on port-ship resonance. The research was carried out in two ports in A Coruña, Spain, using field data, numerical models, and machine learning. It was concluded that the oscillation periods of vessel movements are directly related to the ratio between water depth and ship draft, as well as varying with mooring pretension and strong winds. Operational thresholds based on climatic data (long wave and short wave) were proposed to optimize stays. The thesis culminated in the development of a practical tool that predicts the risk of incidents, which will aid in decision-making. The findings presented have high applicability and potential for transfer to similar facilities for proper risk assessment.
