JoRes1 Tanker – Full Scale Powering Performance

The aim of this test case is to obtain insight into the capability of CFD to predict full-scale trial powering performance. This test case originates from the JoRes Joint Industry Project (https://jores.net/). The hull form features a (mild) bulbous bow, a single propeller with a propeller boss cap fin (PBCF), a horn rudder and an asymmetric centreline skeg. This tanker was the subject of full-scale trials, during which the powering performance (RPM, shaft torque) was measured. Furthermore, a PIV measurement system was installed on board to measure part of the flow coming into the propeller. The surface roughness of the ship was measured and is to be taken into account in the powering predictions. Metrics to be investigated are amongst others the propeller revolution rate, delivered power to the propeller, propeller inflow, wave pattern around the ship, resistance, trim and sinkage.
