Abstract

The pioneers of ship motion analysis often used the symmetry assumption to reduce computation time and complexity. For the symmetry assumption to be valid, a ship must be upright with no heel angle, which is rarely the case. An increased interest in damaged ships has motivated further analysis of ship motions in the asymmetric condition; however, only a limited number of physical experiments have been conducted in towing tanks. This paper presents an experiment carried out to analyze vessel motions in the asymmetric condition for a box barge model. The method includes model construction, experiment setup, the test matrix, and the results. Improved understanding of ship behavior under asymmetric conditions can lead to a more accurate prediction of how a ship will act in response to waves, especially in extreme events. In the companion paper (Sink 2026), the experimental results are compared to General Hydrostatics Software predictions for a full-scale ship. Asymmetrical loading conditions introduce strong coupled motions, especially when trim is also present. Asymmetrical loading conditions also increase the roll response of the model, especially in beam seas.
