| Subject | Design of Cathodic Protection Systems for Deep Water Compliant Petroleum Production Risers |
| Performing Activity | Florida Atlantic University |
| Principal Investigator | Dr. William Hartt |
| Contracting Agency | Minerals Management Service |
| Estimated Completion | Completed |
| Description | Develop a cathodic protection design protocol for deep water petroleum production compliant rises. Results should provide for an Interactive software package on anode/pipeline design, final report and a presentation to industry on software demonstration and project results. |
| Progress |
Conceptual models have been developed that are based upon a zero resistance
source at one end of a riser and a non-zero resistance source at the other.
The former (zero resistance source) is represented by any structure with a
large number of distributed anodes, such as a production jacket, tension leg
platform, or FPSO. The critical task in cp design is to assure that
potential nowhere along the riser becomes positive to the protection
potential (-0.80 Vag/AgCl) during the design life. Proposed Design Procedure
Options that were evaluated for configuring the cp design protocol included
1) the equations of Morgan and Uhlig, 2) Gibson’s equation, 3) the Slope
parameter equations, and 4) the Inclusive Equation.
Final report attached. |
