Final experimental results of full scale fin/rudder roll stabilisation sea trials

Abstract The consequences of roll motions can seriously degrade the effectiveness of ship performance. In order to alleviate roll motions, ships are often equipped with fin stabilisers. Rudders can also generate roll motions and can be harnessed to function in congress with the fins to accrue enhanced levels of stabilisation. This paper reports on the final phase of full-scale sea trials utilising the existing rudders and fins on board a frigate-sized warship. where various control strategies were employed.
