چکیده
Abstract This work presents the experimental research carried out to optimize a current computational software “CorOns”, obtain better ship hull electrical signature modelling. Middle-term ageing (597 days) of anticorrosion paints, highlights appearance additional corrosion processes, despite an absence visual defects. A specific model is proposed for aged surface in seawater based on Electrochemical Impedance Spectroscopy (“EIS”) data analysis. We also investigate impact interruption cathodic protection process, with objective modelling real conditions that could be encountered. These studies’ during 24 h, do not seem have densities. However, EIS studies, highlight interruptions damage calcareous deposit, well-known it protective effect once formed.

متن کاملA Review on the Drag Reduction Methods of the Ship Hulls for Improving the Hydrodynamic Performance
Hydrodynamic performance of a marine vessel mainly depends on the frictional and pressure resistance. Pressure drag reduction could be achieved by improving the shape of the vessels with implementation of modern hull forms. Hull forms optimization techniques could also be used for this purpose. Other techniques are needed to deal with the viscous portion of the total resistance, which is mainly...
