One of the areas where cathodic protection of marine structures is commonly applied is to protect steel piling systems on jetties and piers Every CP design effort begins with a basic decision of whether to use galvanic anodes that operate on the natural potential difference between the anode and the structure or impressed current anodes with an external power supply. This article discusses the design and implementation of cathodic protection on a new construction jetty in one of the country in Far East. In this paper we will discuss the design, materials, installation and commissioning of ICCP system using MMO SLED anodes for cathodic protection of metallic piles.

Key words: ICCP, MMO Sled Anodes, Piles, Marine

External corrosion of tank bottoms is a significant problem for tank owners for both economic and environmental reasons. Corrosion Protection of Above Ground Storage Tanks is typically provided by a impressed current cathodic protection (CP) with or without coatings. Two primary Impressed current CP configurations are used worldwide in tanks. The field-erected mixed metal oxide (MMO) anode grid configuration was an early application of MMO anodes for tank bottoms and has a large global installed base. A newer design to protect tank bottoms is a system of parallel or concentric ring MMO linear anodes with factory connected tail cables.This paper will review the design of “grid” type and “parallel/concentric” linear anode type tank CP designs provide an economic assessment assign a qualitative risk assessment matrix and discuss the implementation impact based on a large grass root tank farm project in Africa. Where the owner/engineers elected to use linear anodes.

This document discusses the issues to be taken into consideration with respect to accounting for corrosion on steel piles in non-marine applications. The rate of corrosion, design life and methods of corrosion control are discussed in a manner to provide the reader with guidance as to how to proceed with determining these factors. This standard is applicable to pipe piles, sheet piles, H piles, and other steel piles.

Steel sheet piles are widely used in permanent earth retaining and structural foundation works. In the majority of circumstances, they can be used in an unprotected condition, such conditions are when the steel piles does not required any coating or cathodic protection system to be protected and depends solely on the corrosion allowance calculations The degree of corrosion and whether protection is required depends upon the working environment - which can vary even within the same project location.


In general, marine environments are the most corrosive and unpredictable. In the few meters of vertical zoning which most structures encompass, parts of the sheet piles are in contact with soil, and exposed to seawater immersion, inter-tidal, splash and marine atmospheric environments.
