Abstract: Case Study – Metallic Jetty Cathodic Protection

Ever since Sir Humphry Davy first applied cathodic protection to protect the British Navy’s ships of war from corrosion, the benefits of cathodic protection in marine applications have been adopted in a wide range of applications. One of the areas where cathodic protection of marine structures is commonly applied is to protect steel piling systems on jetties and piers. This paper discusses the various marine jetty cathodic protection systems.

This paper discusses the design and implementation of cathodic protection on a new construction jetty in Indonesia. Impressed Current, Mixed Metal Oxide Sea-Bottom Anode is a complete, ready to install marine anode sled including the anode cable and protective housing.

The Sea-Bottom Anode is quick and easy to install for cathodic protection of docks, piers, pilings and other marine structures in all types of water. 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 paper will be presented at the NACE Eastern Area Conference 2016.
