Title: NUMERICAL AND EXPERIMENTAL STUDY ON THE CAPSIZING OF DAMAGED RO-RO PASSENGER SHIPS IN WAVES
Abstract: The paper derives from recent research of the Ship Design Laboratory of NTUA on the hydrodynamic behaviour of Ro-Ro passenger ships in seaways in view of recent regulatory developments of IMO (SOLAS 95, Regional agreement, Res. 14) to allow the physical modelling of the damage stability of Ro-Ro passenger ships in waves as an alternative to the so-called ‘water on deck’ regulatory concept. Based on these developments, it becomes evident that the availability of properly validated computer algorithms, allowing the mathematical modelling of the capsize of a damaged ship in waves is of great importance, providing the designer with flexibility and efficiency to address systematically alternative design measures, to so improve the survivability of the ship under question in waves and to allow a ‘pass’ through the required SOLAS regulations. The paper outlines the essence of the employed theoretical-numerical model and includes typical numerical and experimental results for a sample Ro-Ro ship in damage condition. Special emphasis has been devoted to the consideration of “sloshing effects” on the ship dynamics by use of a simplified ‘lump mass concept’.
