Cathodic Protection Design
Cathodic protection system design requires a complex calculations and interpretations to meet the principal objectives while taking care of many factors that are influencing the design. Our experienced team is here to fulfill your demands in any design of CP system.
Our principal objectives for cathodic protection system design are as follows:
- Provide a system design life proportional to the planned structure life time or Client’s requirements.
- Ensure that the safety of the personnel and public, apply all related standards and codes.
- Ensure that a system has flexibility to operate smoothly through its entire design life.
- Minimize or completely remove any interference to other structures.
- Provide sufficient current density to all parts of the structure to achieve polarization criteria.
- Make sure that the system has got enough test points and monitoring systems to be controlled and checked periodically.
- Ensure that the system overlaps the construction specifications.
To achieve above points, there are many factors that could affect the cathodic protection system in both ways as an advantage or disadvantage, which means our consideration covers most of the points below:
- Environmental factors
- Moisture
- pH
- Soil Type
- Oxygen Content
- Temperature
- Any Movement
- Microbiological Activity
- Structure
- Construction Materials
- Geometry
- Voltage Gradients From Current Sources
- Coatings; Organic and Inorganic
- Electrical Isolations
- Groundings
- Stray Current
- Surrounding Structures
- Accessability
- AC Power Availability
- Attenuation etc.
In all our cathodic protection design; we follow (but not limited to) above objectives and check the influencing factors to achieve an efficient and cost-effective overall design.
The basic flowchart that could represent our way of thinking for the CP design is as follow:
