The Hydrodynamic performance of the High-Speed Displacement vessel with and without Hull Vane (HV) systematically investigated using Computational Fluid Dynamics (CFD) software Star CCM+ based on RANSE solver. Hull Vane is an Energy-Saving device (ESD), invented by Dr. Peter Van Oossanen and introduced by Hull Vane BV company to
reduce residuary component of ship resistance and ship motions in waves. HV is a hydrofoil wing transversely fixed at bottom of the transom hull which alters the flow around the stern thereby reduces the resistance of the vessel. Hull Vane alters the flow immediate of the transom and creates low pressure region on the top surface of the HV. This low-pressure region interacts
favourably with stern wave system, thereby reduces the resistance which further result in most desirable trim control. Though research has been carried out in design of the Hull Vane, in this article, effect of Span of the HV, Position in the X-direction and Z-direction of the HV on wave making component of resistance has been analysed. The CFD model is validated with experimental model test results for both the bare hull and Hull Vane case. with the addition of the Hull Vane, a residuary resistance coefficient reduction of 20.81% has been observed at operating Froude number
