Cathodic Protection Numerical Simulation Software and Technical Services
Introduction to the CPVS Numerical Simulation Software
CPVS (Corrosion Protection Visualization Studio) is a software system independently developed by Dalian University of Technology based on the boundary element method (BEM) for simulation. It is specifically designed for corrosion protection assessment of ships and offshore structures. By simply modeling the surface of the structure or domain to be protected and inputting the relevant boundary conditions and environmental parameters, the software can simulate and generate the electrochemical potential distribution across the structure’s surface. Based on these simulation results and in conjunction with design codes and standards, users can evaluate the effectiveness of proposed corrosion protection strategies.

Numerical Simulation and Optimization Design of Cathodic Protection
♦ Operating Condition 1: The sacrificial anode has not been fully consumed, and the tensioned ICCP system coexists with it.
Based on numerical simulation analysis, the jacket structure exhibits good corrosion protection under both operating conditions.
♦ Operating Condition 2: The sacrificial anodes are depleted, and only the tensioned ICCP system provides protection.
Based on numerical simulation analysis, the jacket structure exhibits good corrosion protection under both operating conditions.

Impressed Current Cathodic Protection Monitoring System Software
The monitoring system software has the following functions:
1. Real-time data monitoring
Real-time, continuous monitoring of the cathodic protection status of structures, including data such as jacket surface potential and sacrificial anode current output.
2. Protection Status Alert
Based on the user-defined normal threshold ranges for each cathodic protection parameter, the system continuously determines whether the real-time monitoring data fall within these normal ranges, thereby assessing the status of the cathodic protection system.
3. Data Storage
The computer communicates with the cathodic protection monitoring system, allowing users to set a synchronization interval to upload real-time data sampled by the CPMS to the computer database.
4. Data Playback
Line charts can be used to display potential and current waveforms over a specified time period, providing an intuitive visualization of data trends during that interval and enabling straightforward daily, weekly, monthly, and yearly data playback for all channels.
5. Historical Data Analysis
Perform statistical analysis on the data acquired by the specified sensor over the specified time period, calculating its maximum value, minimum value, average value, and statistical distribution pattern.
Potential data: Real-time display of Ag/AgCl and Zn potential data;
Current Data: Displays the current data from the anode control module in real time;
Voltage Data: Displays the voltage data from the anode control module in real time;
Total current: includes the sum of currents for each composite cable as well as the total current output;
The chart displays potential, current, and voltage data on the left side in tabular form, while the right side shows a diagram of the installation locations for the cathodic protection anodes and reference electrodes.
When the potential data indicates underprotection or overprotection, the corresponding channel’s data column will flash.
Data Monitoring: After setting the data collection interval, click the Start Monitoring button to begin data acquisition at the specified frequency and display the results as a line chart.
Device Filtering: Select the reference electrode and control module; after configuration, the corresponding entries in the chart will be hidden or displayed based on the selection.
Chart Maximization: To focus specifically on the Ag/AgCl data trend, click the maximize button in the upper-right corner of the chart to display it in full-screen mode.
