Abstract
This study presents the results of a workshop conducted within the JoRes framework, focusing on self-propulsion CFD simulation of the full-scale bulk carrier vessel, JoRes5 GRIP. This vessel serves as an ideal validation case, having undergone sea trials both with and without an Energy-Saving Device (ESD)—specifically, pre-swirl stators (PSS). The sea trials were performed at comparable draught conditions (TM = 7.7 m) and across multiple speeds, providing a robust comparative dataset. The vessel, with a length between perpendiculars (LPP) of 182 m, was tested at speeds of 13.65, 15.25, 16.02, and 16.32 kn. These conditions were replicated in the CFD simulations conducted during the workshop, providing insights into the influence of PSS on propulsion performance and enabling validation against full-scale measurement.
