Prediction of the Effectiveness of Flopper-Stopper Roll Damping Device.

Abstract

The effectiveness of a series of flopper-stopper roll damping devices on a Torpedo Weapons Retriever at zero speed in random beam seas was investigated. The ship was modeled as a one-degree-of-freedom system, and the flopper-stopper was modeled as an equivalent linear damping element based upon a detailed analysis of the forces on the device. The tension in the cable of the flopper-stopper was also estimated. The flopper-stopper was found to be an effective roll damping device. (Author)
