ANALYSIS OF WAVE FORCE DATA

Wave profile and wave force data acquired in the Gulf of Mexico from several hurricanes have been analyzed to provide the drag and inertial coefficients of Morisons wave force quation. These coefficients are required to help determine design loads for offshore structures. An analysis, using nonlinear wave theories, of profile and force data from waves in shallow water gave drag and inertial force coefficients of 0.5 and 1.2, respectively. Data acquired in 100 ft of water gave a slightly larger drag coefficient ( 0.58 ) and a larger inertial coefficient ( 1.76 ). Good agreement between measured and predicted forces was observed.
