Abstract
Computational and experimental methodologies are often seen as competing
resources. This is unfortunate because in the evaluation of complex physical
phenomenon often both methodologies are required to develop a complete
understanding of the underlying basic science as well as an understanding of the
system level behavior. Even though the title implies a contrasting of methods,
this work will present how computational methods can be used to supplement
experimental techniques and visa versa. Electrochemical corrosion is a complex
natural phenomenon that has been studied for many years, however corrosion
mechanisms as well as corrosion protection are still not completely defined. The
prevention of ship hull corrosion is a major concern for the US Military and the
commercial shipping industry due to the large monetary and long-term
investment. This paper discusses the physical scale modeling (PSM), shipboard
impressed current cathodic protection (ICCP) design technique, how
computational methods can be used to augment the design process and presents a
number of experimentally determined factors that should be applied to present
mathematical code development to improve the computational approach to
cathodic protection system design.
Keywords: cathodic protection, boundary element modeling, impressed current
cathodic protection, physical scale modeling.
1 Introduction
The need to protect ocean-going vessels from corrosion has existed as long as
man has explored the oceans. Today a common approach to corrosion
prevention is the use of Impressed Current Cathodic Protection (ICCP) systems.
Cathodic protection systems take advantage of the inherent electrochemical
