ASSESSMENT OF NPL ROLL STABILISERS IN SERVICE

Describes the performance of passive tank roll stabilizer installations in thirteen vessels of widely differing type, ranging from a pilot cutter to a 151 meter container ship, and discusses the extent to which model experiments were successful in predicting the performance of the installations at sea. Describes the design procedure developed by Ship Division of the National Physical Laboratory and compares the results of model experiments in irregular beam seas with the results of trials performed on the corresponding ships. Also described are the comprehensive sea trials carried out by the British Ship Research Association on the research vessel 'Corella' in which a wave buoy was used to monitor the sea state. A detailed comparison is given of ship and model roll response operations in beam seas. Recommendations are made for model test procedures which should result in improved correlation of ship and model roll stabilizer performance.
