Shall we consider only large vessels for ship-scale CFD validation?

Sea Trials

Obviously, EEXI, EEDI and CII are applicable to large vessels only, so the primary focus of energy efficiency and performance investigations should be on these vessels. However, can we learn something if we perform ship-scale CFD validation on a smaller vessel?
We believe we can! JoRes team has recently performed sea trials of an 18m tug boat. This is a good test case for the project as we will better understand the effect of hull and propeller roughness (which have similar values to large vessels!). For this vessel we performed high-fidelity speed-power, manoeuvring and bollard pull trials.
Now it is time to analyse the results and prepare 3D geometry. Stay tuned!
