DNV-RP-B401 – Cathodic Protection Design
What’s the point in having anodes lasting longer than the coating? Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor. It appears that you need to dnv-rp-v401 a and t to do this problem. I’d say that if you don’t know a, b and t, you should not be trying to use equation 3.

Kind regards, Sadik Hussain. Below is the statement: Do let me know if you need any clarifications. Red Flag This Post Please let us env-rp-b401 here why this post is inappropriate.

I am hoping someone could elaborate the following part, ‘When the design life of the CP dnf-rp-b401 exceeds the actual calculated life of the coating system according to 6. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Kind regards, Sadik Dnv-rp-h401 RE: Ideally you would like both durations to be similar since it is beneficial to replace them together.
But sometimes Owners tend to specify different durations say 5 years for the anodes and 3 for the coating. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.
So this lead to increased demand on the number of anodes and the design current etc. Another factor is periodic cleaning of marine growth in this zone.
That’s what you want to do?
Resources Few production environments have the luxury of ordering new dng-rp-b401 to replace existing machines on their shop floor. The effect of marine growth is highest in the upper 30 meters where wave forces may further contribute to coating degradation. So you consider the influence of the coating for the first 3 years and for the remainder, calculate without it. By joining you are opting in to receive e-mail.

Such issues are the result of project complexity, size, uniqueness and regulation, as well as the need for virtual team collaboration. Are you an Engineering professional?
You should size the anodes based on an assumed amount of coating damage and a anode lifetime. The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage potential project delays and costs. Join your peers on the Internet’s largest technical engineering professional community. 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.
As a simple engineering approach, fc can be expressed as: I think the Cathodic Protection Systems were designed previously without considering the influence of coating on the corrosion behavior.
