Deepwater Granted Mexican Patent for CP Mat

Deepwater Corrosion Services reports that, on March 4, 2008, the company’s pending Mexican patent for the CP Mat ( Stabilizer With Cathodic Protection) was granted. With the receipt of patent number 130524.2002, the company says CP Mat is now patented in both the U.S. and Mexico.

The company says the system is undergoing extensive research and development, with the aim of including cathodic protection monitoring equipment. This new “smart” mat would allow for reliable CP in deep water, where interrogation and maintenance can only be achieved with ROVs (and in the near future AUVs).

The system combines a concrete stabilization mattress and cathodic protection system in one. By casting abodes directly into the concrete segments, the company says a standard mattress can now provide cathodic protection for pipeline crossings, pipelines in harsh bottom conditions, and many other applications.
