Powering Calculation made by Steerprop
Preliminary powering prediction for the ferry is made using lines plan andstatistical power prediction method "Holtrop". Powering curve with KVL=4.6m isshown in the following. The maximum speed of the vessel according to thisprediction is about 20.1 knots.
Powering calculation with KVL = 4.6m at 20 knots:Pe (No sea margin) 3889 kW;Hull efficiency (estim) 0.946;open water efficiency 0.740;Delivered power 2x2777 kW;Braked power 2x2922 kW.
