Used in conjunction with the BEASY Corrosion & CP the BEASY ICCP Optimisation software provides a comprehensive solution for engineers who need to Optimise ICCP system operation
Automatically determine anode currents required to achieve required potential
Identify optimum reference electrode locations
Design ICCP control parameters
Minimise electric and magnetic signatures
Predict the ICCP anode currents required to achieve the protection requiredWith the BEASY ICCP Optimisation software you can define the goals of the simulation and the constraints on the design. For example the user can:
Define the target potentials on the vessel
Define the maximum and minimum potentials to avoid under and over protection
Specify that the potentials on the vessel should be as even as possible
Given this data the software automatically adjusts the anode currents until the best design is achieved within the constraints of the power supply of the ICCP system.In this way the settings for the optimum uniform protection of the vessel under the vessels operating conditions can be determined.
Initial Design Overprotected and excessive current.
Final Design. BEASY ICCP Optimisation
software achieves target potential with more uniform
protection and balanced current outputs from the anodes.

Minimise the electric fieldThe surrounding electric field (and consequently the associated magnetic field) can be minimised automatically to achieve the minimum corrosion related signature. For example the user can:
Define the maximum and minimum potentials to avoid under and over protection
Specify the location where the signature is to be measured
Given this data the software automatically adjusts the anode currents until the configuration which provides the minimum signature is determined.
Search for the optimum anode and reference cell locationsUsing the BEASY ICCP Optimisation software the search for the optimum locations for the anodes and reference cells can be efficiently performed. For example the user can define a series of models representing:
The possible designs of the ICCP system including the number of anodes and their location
The target potential required on the vessel or structure
The maximum and minimum potential to be allowed to avoid under or over protection
The capacity of the ICCP power supplies
Each model can then be run to determine the anode currents which will achieve the target potential at all locations on the vessel or structure, and the most uniform potential distribution within the constraints of the ICCP power supplies. These results provide the user with information on the best performance for each design of the ICCP system.If the signature of the vessel is the main concern then the objective can be changed from the most uniform potential distribution to the minimum signature.
