I think the Cathodic Protection Systems were designed previously without considering the influence of coating on the corrosion behavior.
DNV-RP-B CATHODIC PROTECTION SYSTEM – Off-shore structure engineering – Eng-Tips
dnv-rp-4b01 Another factor is periodic cleaning of marine growth in this zone. Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor. But sometimes Owners tend to specify different durations say 5 years for the anodes and 3 for the coating.
When the design life of the CP system exceeds the actual calculated life of the coating system according to 6. Close this window and log in.
Download Now The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to dnv-rp-b01 manage potential project delays and costs. So this lead to increased demand on the number of anodes and the dbv-rp-b401 current etc. It’s easy to join and it’s free. As a simple engineering approach, fc can be expressed as: Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.
Red Flag This Post Please let us know here why this post is inappropriate. Biginch, Yes it would be preferable if you size the anodes based on the coating life.

What has been done looks like two calculations, picking the biggest number. Register now while it’s still free! So you consider the dnv-gp-b401 of the coating for the first 3 years and for the remainder, calculate without it. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. It appears that you need to know a dnv-ep-b401 t to do this problem. What’s the point in having anodes lasting longer than the coating?
DNV-RP-B401 – Cathodic Protection Design
I’d say that if you don’t know dnv-rp-b4001, b and t, you should not be trying to use equation 3. The Eng-Tips staff will check this out and take appropriate action.
Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Such issues are the result of project complexity, size, uniqueness and regulation, as well as the need for virtual team collaboration. Below is the statement: Kind regards, Sadik Hussain RE: Ideally you would like both durations to be similar since it is beneficial to replace them together. That’s what you want to do?

Kind regards, Sadik Hussain. You should size the anodes based on an assumed amount of coating damage and a anode lifetime.
Are you an Engineering professional? Resources Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor. By joining you are opting in to receive e-mail.
But over the last few years Coatings have been found useful in contributing positively to the CP cause which led to a considerable reduction in the usage of anodes. Do let me know if you need any clarifications. The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage potential project delays and costs.
The effect of marine growth is highest in the upper 30 meters where wave forces may further contribute to coating degradation. I am hoping someone could elaborate the following part, ‘When the design life of the CP system exceeds the actual calculated life of the coating system according to 6. So rnv-rp-b401 point is basically that you need two sets of design lifeone for CP sytem and the other for the coating you apply to the structure.
But then how do we calculate t if we don’t know f in eq 3.
