The Seaworthiness of a Training Ship “Naše more” in Heavy Seas

Safe navigation depends on many factors, such as the maneuverability and stability of the ship, the nature of the waterway, the sea state and other external factors and, above all, the seamanship of the mariner. Therefore, it is necessary to analyze the movement of the ship in different conditions. The seakeeping analysis is usually done by model tests and/or calculations during the design stage, while full-scale measurements in real conditions are very rare. This paper presents the full-scale measurement of a training ship motion in heavy seas as part of a research project entitled “Modelling Uncertainty of Ship Wave-Induced Response in the Adriatic Sea (MODUS)", fully supported by the Croatian Science Foundation. The experiment was performed on the training ship “Naše more” in the port of Dubrovnik. The wave height ranged from 4ft to 6ft with SE wind. The waves came from the direction of 180 ° to 183°. The wave buoy SPOTTER was used to collect the data on the movement and height of the waves. The ELLIPSE2-N-G4A2-B1 sensor recorded the ship’s behavior and was placed on the bridge.
