The shipping industry plays a crucial role in global trade, responsible for transporting over 80% of goods worldwide. However, it also contributes to greenhouse gas (GHG) emissions, making it a major focus for sustainability efforts. The International Maritime Organization (IMO) has set ambitious targets to reduce GHG emissions from shipping, including both short-term measures and long-term strategies to decarbonize the industry. The goal is to reduce GHG emissions by at least 50% by 2050 compared to 2008 levels. To achieve these targets, the shipping industry must continuously innovate and implement operational and technical solutions to optimize vessel performance and reduce fuel consumption. One operational solution is to optimize a vessel’s static trim, as it has a significant effect on its resistance and propulsive power. This study investigates the effectiveness of trim guidance for a 237 m Container Ro (Con-Ro) vessel by performing model-scale RANS (Reynolds-averaged Navier-Stokes) CFD (Computational Fluid Dynamics) resistance and self-propulsion simulations at different speeds, trim angles, and loading conditions. These parameters were derived from the vessel's actual operational profile. The CFD resistance and self-propulsion simulations were validated against available towing tank test results.

Abstract
The shipping industry plays a crucial role in global trade, responsible for transporting over 80% of goods worldwide. However, it also contributes to greenhouse gas (GHG) emissions, making it a major focus for sustainability efforts. The International Maritime Organization (IMO) has set ambitious targets to reduce GHG emissions from shipping, including both short-term measures and long-term strategies to decarbonize the industry. The goal is to reduce GHG emissions by at least 50% by 2050 compared to 2008 levels. To achieve these targets, the shipping industry must continuously innovate and implement operational and technical solutions to optimize vessel performance and reduce fuel consumption. One operational solution is to optimize a vessel’s static trim, as it has a significant effect on its resistance and propulsive power. This study investigates the effectiveness of trim guidance for a 237 m Container Ro (Con-Ro) vessel by performing model-scale RANS (Reynolds-averaged Navier-Stokes) CFD (Computational Fluid Dynamics) resistance and self-propulsion simulations at different speeds, trim angles, and loading conditions. These parameters were derived from the vessel's actual operational profile. The CFD resistance and self-propulsion simulations were validated against available towing tank test results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
