An optimisation-based approach to reduce fuel consumption and emissions from shipping navigation. International Marine Design Conference. https://doi.org/10.59490/imdc.2024.832http://hdl.handle.net/10400.26/59700This study presents an optimisation-based approach to reduce fuel consumption and emissions from shipping navigation. The main objective is to improve energy efficiency and simultaneously turn a case-study vessel compliant with Carbon Intensity Indicator (CII) proposed by IMO. This optimisation module has been devised as part of a new robust integrated real-time digital solution that will involve a significant number of both technical and operational measures in practice aiming to optimise operational efficiency (during navigation and port calls). Namely, the tool will be capable of situational awareness and decision support to reduce fuel consumption and Green House Gas (GHG) emissions from shipping and must be combined with intrinsic vessel systems to improve vessel hydrodynamic performance, resulting also in improved vessel safety and widening of the operational weather windowengShip energy efficiencyReal-time fuel consumption estimationHydrodynamic optimisationWeather routingVectorized simulated annealingconference paper10.59490/imdc.2024.832
