Try a pipeline engineering corporation. There are a number of them in California that deal with Cathodic Protection. Try contacting one of the many Boyle Engineering Corporation offices, they design many pipelines and might be able to help.

NACE (www.nace.org), the National Association of Corrosion Engineers, provides training and certification in numerous aspects of corrosion and protection against same (including cathodic protection). BIG differences between pipelines on land (groundbed anode arrays, usually with carbonaceous backfills, fed by rectifiers) and offshore pipelines (usually bracelet anodes of aluminum/zinc/indium alloy). Lots of salespeople in this arena will gladly sell you either whatever they need to "push" at that point-in-time, or what they THINK it is that you want, whether right or wrong. Only knowledge will provide the BEST product(s) for your application. Visit nace.org and sign-up for their [nace] Corrosion Network (ListServer) and post your question to the real experts! Participation from all 'round the world.

Your assistance cannot go un-noticed. Thanks a million times , you are really wonderful!
