... The recently developed slope parameter approach to design of galvanic anode cathodic protection (cp) systems for marine structures constitutes an advancement in this technology compared to current practice, primarily because the former is first principles based and the latter is an empirical...

... The goal of impressed current cathodic protection (ICCP) design for ship hulls, under the Navy Ship's Technical Manual (NSTM, Chapter 633), is to provide a uniform potential distribution at -0.85 V, ± 0.05 V, versus a silver/silver chloride (Ag/AgCl) reference cell, over the wetted hull surface...

... Corrosion of steel pilings in sea and brackish water is mostly due to the establishment of localized corrosion cells and the effects of the tidal changes. The most frequently used corrosion protection systems are coatings and/or cathodic protection. These protective systems when properly...

... Field and laboratory experience related to requirements for cathodic protection (CP) in deep water are reviewed with emphasis on identification of the major variables that need to be specified for successful deepwater CP designs for offshore structures. The subject is addressed based...

... Computational modeling using boundary element techniques has been proposed for design and evaluation of shipboard impressed current cathodic protection (ICCP) systems. LaPlace's equation, the governing differential equation for electrochemical corrosion, is well suited for solution...

... Corrosion protection of the space shuttle solid rocket boosters incorporates the use of cathodic protection (anodes) in concert with several coatings systems. The SRB design has large carbon/carbon composite (motor nozzle) electrically connected to an aluminum alloy structure. Early in the STS...
