Abstract
Impressed current cathodic protection (ICCP) systems and computer modeling using boundary element techniques are independent established technologies. The application of boundary element methods to the design of ICCP systems will result in the development of more effective and more efficient ICCP systemx. Three analyses are highlighted in the presentation. In two analyses, detailed comparisons are made between physical scale modeling (PSM) and computer modeling results. PSM results are defined as the baseline that computer modeling results are compared with to determine the applicability and accuracy of the technique. The first analysis performed uses U.S. Navy CG Hull Class and examines issues of mesh refinement and material characterization accuracy. In the second analysis, PSM and computer analysis for the CG Hull Class are directly compared with sea trial data. In the final analysis presented issues of scale and material characterization are examined using a model of a U.S. Navy CVN Hull Class ship.
