Optimizing Hydrodynamic Performance in Dry Dock With strict EEXI and CII regulations in force, optimizing vessel hydrodynamic efficiency during scheduled dry-docking is no longer optional. Two of the most effective interventions for reducing fuel consumption and greenhouse gas emissions are the installation of wake-equalizing devices and advanced foul-release coatings.
Wartsila Energo Flo Installation The Wartsila Energo Flo is a highly effective energy-saving device featuring stator fins that optimize the water flow into the propeller. Proper installation requires meticulous coordination between the shipyard and the technical team. Precision in welding the fins to the hull and ensuring exact alignment with the propeller shaft axis is critical. Misalignment can negate the fuel-saving benefits and induce unwanted vibrations.
XGIT Propeller & Hull Coating Procedures Applying an XGIT propeller coating or executing full hull painting procedures requires strict environmental control. To achieve the lowest possible friction coefficient:
Surface Preparation: The propeller must be polished to the manufacturer’s exact roughness standard before application.
Curing Times: Coating applications must strictly follow temperature and humidity guidelines to ensure proper curing and long-term adhesion.
Inspection: Thorough dry-film thickness (DFT) checks must be documented at every stage.
⚙️ Managing a dry dock with spotty internet? Technical Superintendents and Chief Engineers can’t afford to lose access to installation manuals and ER diagnostic checklists when shipyard Wi-Fi drops.
