Rather than assessing individual technologies in isolation, the project will evaluate the combined impact of multiple energy-saving devices applied as an integrated system.  The approach reflects a broader shift within the industry towards whole-vessel performance, particularly as operators face more stringent emissions and environmental rules along with rising fuel costs. The technical scope centers on the integration of a new flow-aligned twisted rudder, dubbed EcoVane, EcoNavis’ proprietary propeller hub Eco Boss Cap, and pressure-relieving modifications to the propeller blades. Each element targets a different source of hydrodynamic loss, from wake misalignment and drag at the rudder to vortex formation and cavitation at the propeller hub and blades. The figures will be validated through controlled before-and-after sea trials, including direct measurement of shaft power and acoustic output. The work will begin with computational modeling to establish a performance baseline for the selected vessel, followed by iterative design optimization using vessel-specific flow analysis. Manufacturing, installation and full-scale trials will then be carried out, with all performa
