Flanders Hydraulics Research built a 1/80 scale model in which three different ship models have been experimented to assess the navigation behavior in the Third Set of Panama locks. The radio controlled ship models were laterally restrained, equipped with an own propulsion and longitudinally assisted by simulated tugs. During the tests forces exerted on and vertical motions of the ship, as well as water levels were recorded. A limited number of tests included density currents, which mainly occur between the first lock chamber and the ocean side. All typical lock maneuvers have been tested at different approach wall configurations, eccentricities, propeller rates, approach scenarios and under keel clearances. This article presents a selection of results of interest for lock maneuvers, among which the significant effect of density currents and the approach wall configuration on the lateral forces that act on the entering and exiting vessels. Control of lateral forces by the ship’s controls and tug assistance is therefore a determining parameter.
