Impressed Current Cathodic Protection System For Ships
Therefore the system is much more effective and reliable than sacrificial anode systems where the level of protection is unknown and uncontrollable.
Impressed current cathodic protection system for ships. Our systems work by supplying a controlled amount of dc current to submerged surfaces using highly reliable mixed metal oxide anodes and zinc reference electrodes. Impressed current cathodic protection iccp systems consist of one or more reference electrodes and several iccp anodes which are all connected to a power unit. This animation shows how cathelco impressed current cathodic protection iccp systems protect the hulls of commercial vessels against corrosion. Impressed current cathodic protection on ships iccp corrosion by sea water is an electrochemical process in which the ship hull acts as electrode and sea water as electrolyte.
We will start with basics and then move on to the original setup which is used on ship. Impressed current cathodic protection systems are preferred by ship owners because they reduce fuel cost and maintenance. Capac systems are a long term solution for corrosion problems on ship s hulls. They have long been recognized as the superior alternative to other cathodic protection systems which require frequent replacement and experience increased fuel and maintenance costs.
Impressed current cathodic protection iccp system an iccp system uses positive current to prevent corrosion. The external power source often a dc power supply provides the current necessary to drive the electrochemical reaction required for cathodic protection to occur. Impressed current cathodic protection iccp is a corrosion protection system consisting of sacrificial anodes connected to an external power source. Ship hull is the most severely affected part when it comes to contact with seawater.
Learn how impressed current cathodic protection on ship works and what is the need of putting such system. 2material science and technology division naval research laboratory washington dc. The reference cells measure the underwater electrical protection potential and based on this data the power unit regulates the required output to the anodes.
