EXPERIMENTAL EVALUATION OF A PASSIVE ANTI-ROLL TANK SYSTEM

The effectiveness of the passive anti-roll tank system aboard the R/V Yaquina was determined. Measurements of ship roll, effective waveslope and tank water transfer were analyzed using a systems analysis technique. Time series of the inputs and outputs of the ship-tank system and of the tank itself were processed using spectral analysis methods to obtain system transfer functions for stabilized and unstabilized configurations. Comparison of these transfer functions showed that the anti-roll tank system has a significant and beneficial effect on the rolling performance of the vessel. However, all tests were made with seas approaching on the beam and therefore, no conclusions about the tank's effectiveness in reducing yaw-heel rolling, especially very long period rolling resulting from follwing seas can be made.
