Abstract

A ship’s nominal wake fraction is a key parameter in the designof the marine propulsion system, i.e. the the marine propulsorand main engine. Determination of the wake fraction iscommonly done through empirical formulas and / or based onmodel-scale experiments. However, a discrepancy exists betweenthe model- and full-scale estimation results because ofthe way scaling is applied. Speed trials are conducted to estimatethe full-scale nominal wake fraction. Results show theability of the developed speed-trial methodology to provide aninitial estimation of the full-scale nominal wake. However,comparison between the empirical, model-scale, and full-scaleresults fails to provide conclusive results. No real insight intothe validity of the estimated full-scale nominal wake fractioncould be established. However, the applied methodology isdeemed to have value but additional research is required beforefurther conclusions can be drawn.
