PRELIMINARY ROLL STABILIZER SIZING PREDICTIONS FOR A U.S. COAST GUARD MEDIUM ENDURANCE CUTTER (WMEC)

This investigation provides roll motion predictions for a U.S. Coast Guard 270-foot Medium Endurance Cutter (WMEC). The predictions are used to assess the roll stabilization obtained with various sizes of bilge keels and active fin stabilizers. The predictions indicate that a reasonable roll response can be obtained with 9.67 square meters (104 square feet) bilge keels located aft of 2.32 square meters (25 square feet) active fin stabilizers. At higher ship speeds this stabilizer configuration should provide adequate roll stabilization for helicopter operations at all headings for most sea conditions with significant wave heights of around 3 m (9.8 ft).
