WIND HEELING LOADS ON A NAVAL FRIGATE

This paper describes a series of wind tunnel tests examining wind-induced heeling loads on a generic naval frigate. The objective of the experiments was to provide new data for improving stability criteria for naval frigates. The wind tunnel environment models the wind velocity profile over the ocean during storm conditions, which are of greatest interest for ship stability. A series of five different models represents the ship at heel angles of 0, 20, 40, 60, and 70 degrees. Wind directions for testing range from 0 to 360 degrees relative to the bow, thus giving results for the ship heeling to both leeward and windward. Measured wind heeling moments are shown to be much greater than those predicted by current naval stability criteria. Contrary to the existing criteria, wind heeling moment exhibits surprisingly little reduction as heel angle increases. The experimental data indicate that existing stability criteria should be revised to model more accurately actual wind loading.
