SEA TESTS ON A SWING-MOORED AIRCRAFT CARRIER.
NAVAL CIVIL ENGINEERING LAB PORT HUENEME CALIF
Sea tests involving motions and forces were con ducted on the CVU-91, a deactivated Casablanca class aircraft carrier. The ship was swing moored by a 2-12-inch die-lock chain in about 372 feet of water in the Pacific off Southern California. Water-level variations, ship ro tations and accelerations, mooring force, and wind velocity and direction were measured in sea states of 5 and 6. Two records, of 34 minutes each, were analyzed, using time-series techniques to relate the motions and forces to the water level variations. Apparent amplitude response operators were obtained for all the ship motions and the mooring force. It was concluded that the mooring chain was loaded lightly and affected only fishtailing test- and model-derived re sponse operators for pitch and roll agree well over a limited range heave and pitch can be deduced by separation of measurements of acceler a-n made at bow and stern.
