Data obtained by ship instrumentation from a few simple trials of the EXXON PHILADELPHIA (75,000 DWT) during a routine voyage was analyzed with the system identification techniques. This resulted in a reliable 'measurement' of the full scale resistance, wake fraction, thrust deduction factor, propeller thrust and the linear and non-linear coefficients in the maneuvering equations of motion. Comparison between these full-scale measurements and those obtained through extrapolation of scaled model test results indicated significant scale effect. The authors believe that this successful 'measurement' of the resistance of a large ship is a first.
