MODEL TESTING IN THE NATURAL ENVIRONMENT

The application of stochastic methods to vessel model testing in the natural environment is discussed. A scale model of a seagoing barge with a beam-to-length ratio resembling a ship form was tested. The tests were performed in Puget Sound using a fixed wave probe facility. Model motion was obtained using a vessel response monitoring system previously developed using gyroscopes and servoaccelerometers as sensors. The computer reduction of the data and comparison to direct computer calculations of the response operators is discussed.
