where i found a web site to explain the concept & principle of pipeline cathodic protection buried & marine?

 

For a simple explanation try here:

For a more detailed explanation of using CP in a marine environment you might try here:

http://www.delweg.com
http://www.globalcathodic.com
http://www.deq.state.mi.us
http://www.epa.gov
http://www.state.sd.us

If these do not help, I'll check if our system manufacturer has a web site.
I would also try some of the Swedish, Norwegian, UK and USA university/engineering college sites.
