Verification of the effectiveness of energy saving devices

Abstract

ABSTRACT Four examples for the verification of the effectiveness of energy saving devices by full-scale investigations are given. In each case, the power saving is predicted by model tests. Sometimes, these model tests are already regarded as verification of the gains. Nevertheless, usually sea trials are performed to investigate the prognosis in full-scale. For the given examples, the author has performed the measurements during the S/P trials. Analysis of the sea trial results and comparison with the model test results are presented. Finally, an assessment of the different verification methods is given.
