Project Number 243
Date of Summary June 15, 2001
Subject Cathodic Retrofits for Offshore Structures
Performing Activity Florida Atlantic University
Principal Investigator Dr. William H. Hartt
Contracting Agency Minerals Management Service
Estimated Completion Complete
Description This was a Joint Industry Project (JIP). The objectives were to establish a protocol for determining if and when the cathodic protection system on a particular structure should be retrofitted and to define a design practice for cathodic protection retrofits in cases where retrofitting had been determined to be necessary.
Progress A procedure for calculating the resistance of a conductor array was introduced. The slope parameter and the optimum anode design can be determined from this. Resistance of a miniaturized, simulated conductor array was measured in seawater; the results were compared with results from the analytical design method.

A workshop was held in conjunction with project #242 in Galveston, Texas on Feb 7-10, 1999. Proceedings are available upon request.

The project was completed in January 2000.
