| Abstract: |
| Due to development of electromagnetic field detection technology and application of intelligent mine, corrosion related electromagnetic field has serious influence on stealth and safety of ship. In order to comparatively study the characteristics of electromagnetic field when there was no cathodic protection, the ship was protected by impressed current cathodic protection and sacrificial anode respectively. Computer simulation technology was tentatively used to calculate the strength of electric and magnetic field. Simulation results showed that corrosion related electromagnetic field has its own unique characteristics, and the electromagnetic field induced by impressed current cathodic protection was the strongest one, and the electromagnetic field induced by sacrificial anode was stronger than that when there was no cathodic protection. |
