Abstract: SAFEPORT safety system aims to daily reports to Sines harbour administration, potencial emergency situations regarding ships operation in port areas caused by extreme weather-oceanographic conditions, that may occur in the next three. It consists of a set of numerical models and a qualitative risk assessment and forecasting. It uses forecasts provided offshore of the area under study of sea agitation, wind and tide. The characterization of the response of the free and moored ships at a berth is performed using the numerical models which deals with formulations in the frequency and time domain. The system issue alerts, through danger levels associated with risk levels of exceedance of recommended values for movements and forces imposed on ship mooring systems. SAFEPORT can be adapted to any port. So far, it has been developed and adapted to three terminals of the port of Sines, where three different ships were simulated. This paper presents the developments made to date of the safety system, in terms of its implementation and validation. The numerical models run every day, in real-time mode, in a computer cluster and the system provide forecast results for the next 72 hours. The results are disseminated on a web page and a mobile application in a variety of formats.

IXSemengo2022_BlueSafePort-ENMC2022_Pinheiroetal.pdfA ship can move in six modes of oscillation: surge, sway, heave, roll, pitch and yaw. The introduction of mooring lines in the process of berthing ships allows the restriction of oscillations in the horizontal plane, namely surge, sway and yaw (Santos, 2010), preventing that the amplitude of these movements does not exceed the limits considered admissible.1.71 MBAdobe PDFView/Open
