Abstract
The port of Katakolo is located in the Kyparissian Gulf, where the escape of natural gas is being observed. Result of this systematic leakage is the formation of circular depressions, known as pockmarks, which undermine the integrity of the seabed where port infrastructures might be established. This study investigates the current condition of pockmark formations inside the port of Katakolo, following an incident that occurred in 2009, when sections of the commercial quay sub-sided. Additionally, it studies the morphology and activity of these features and their potential influence on the structural integrity of the port. Detailed bathymetric data, using a multibeam echosounder, were collected and studied. The generated 3D model of the port indicated the presence of active pockmarks, which exhibit elongated, normal and unit shapes, primarily located near the commercial pier, that indeed impose threat to the structural integrity. By identifying the morphology and distribution of these features, this study emphasizes the significance of integrating seabed assessments into port maintenance strategies. The findings also highlight the need for continuous monitoring and adaptive engineering approaches to ensure the long-term stability and operational safety of existing and future port infrastructures.
