CFD-Powered Ship Trim Optimization: Integrating ANN for User-Friendly Software Tool Development

Journal of Marine Science and Engineering, Год журнала: 2024, Номер 12(8), С. 1265 - 1265

Опубликована: Июль 27, 2024

This study presents a comprehensive approach to trim optimization as an energy efficiency improvement measure, focusing on reducing fuel consumption for one RO-RO car carrier. Utilizing Computational Fluid Dynamics (CFD) software, the methodology incorporates artificial neural networks (ANNs) develop mathematical model estimating key parameters such brake power, daily oil (DFOC) and propeller speed. The complex ANN is then integrated into user-friendly software tool practical engineering applications. research outlines seven-phase process discusses its potential extension other types of ships, aiming establish universal CFD-based analyses. Based results, biggest DFOC goes up 10.5% at 7.5 m draft 8% higher drafts. Generally, in every considered case, it recommended sail with towards bow, meaning that ship’s longitudinal center gravity should be adjusted tilt slightly forward.
