TY - CONF A1 - Romero-Navarrete, José A. A1 - Otremba, Frank T1 - Modelling of the lateral stability of river tankers T2 - NAFEMS 2017 - Proceedings N2 - A model of the cargo – ship interaction has been presented, for a navigation environment in which there is no waves, in which the ship lateral stability depends only on the manoeuver performed and the characteristics of the ship and cargo. Several simplifications have been introduced in the model, including the circular bottom of the ship, which facilitates the location of the buoyancy force on the ship, and the analogy of the sloshing cargo motion to a simple pendulum. Two forms of damping were introduced (river waters with the ship´s hull and the friction of the liquid inside the tanker walls), while the sliding motion of the ship when turning has been assumed as negligible. The results suggest that the sloshing cargo influences the lateral stability of the river tanker, with increases in the maximum roll angle from 15% to 40%, as a function of the speed and the fill level. The maximum roll angle has been found to occur at a 75% fill level, regardless of the ship speed.
