Ships are often exposed to very harsh marine environments. Due to the environment in which they operate, the ship’s hull is often exposed sea environmental corrosion that can reduce the life.

The corrosion of seawater as regards to general corrosion on steel increases with increasing temperature, oxygen content, water velocity, the content of corrosive contaminants, eroding particles, and conductivity. The seawater containing salt forms a perfect electrolyte with the ship’s hull, fully made up of iron (mild steel), to form a galvanic cell.

Galvanic cell occurs when two dissimilar are in contact with each other leads to corrosive medium (electrolyte) i.e. the more active metal undergoes corrosion and the less active metal acts as a cathode and stays protected. Like that way, people use to paint the ship hull. But it is impossible to paint often, since it can done only in dry dock condition.

So that people go for depressed current cathodic protection system with sacrificial anodes like aluminum, zinc, magnesium and GI anodes. But we should replace the anodes in very short period. 

Impressed current cathodic protection with MMO Coated and Platinum plated Titanium and Niobium anodes will last longer for 15 to 20 years and reference electrode for monitoring the system.

MMO COATED TITANIUM/NIOBIUM RUBBERIZED DISC ANODE AND ZINC REFERENCE ELECTRODE FOR CATHODIC PRODUCTION USED TO PROTECT THE SHIP HULL FROM SEA WATER CORROSION

clock May 13, 2021 11:53 by author admin

MMO (Mixed Metal Oxide) coated rubberized disc anodes are used to protect the ship or hull from sea water corrosion. Normally Titanium having noncorrosive, but it contains nonconductive material. MMO coated will give the conductivity in titanium as per the application and amperage. Zinc reference electrode will be placed in particular distance as per the cathodic protection system to monitor the conductivity of the MMO coating disc.   

Sea water is very corrosive environment because the salt present in it makes very good conductor of electricity. It creates a lot of free irons which accelerate oxidation of iron (mid steel) which made of oxidation.

When using MMO coated rubberized disc anode to protect the ship hull from sea water corrosion, external current are applied to convert high-potential anodic sites on a ship hulls to low-potential cathodic sites. This ensures the ship hull surface is protected from corrosion.

We can install MMO coated disc in the hull by passing DC current by a rectifier which will protect the ships life longer nearly 20 to 25 years depends upon the usage of the ship which afloat often.  

MMO coated rubberized disc size well be customized depends upon the design of the CP system.

Advantages:

  • Ø  Durability compared to galvanic anode.
  • Ø  Demonstrate reliability.
  • Ø  Optimum documented corrosion production at minimum overall cost.  
  • Ø  Anodes are lite, sturdy and compact for easy shipping, storage and installation.

Platinized rod used in cantiliver anodes with active part of plating to protect the gigantic pump internals, suction, condenser box and pipelines etc.,

Platinum is an excellent catalyst due to its high conductivity and low consumption rate. Platinum deposition made by electroplating method over a high corrosion resistance substrate (Titanium). Since Titanium substrates is having non-corrosive nature form by insulating oxide film by platinum plantings.

Platinized titanium rod are usually used in cantilever anode which is used for protecting pipeline internals, suction and condenser box internal for 30 years and more by applying DC current with transformer rectifier. Normally titanium is well known for its high resistance to corrosion both water and chemical media but titanium is the poor electricity conductor. So we use platinum/ MMO plating/ Coating to increase the conductivity.

 Advantages:

  • Ø  Low consumption rate that conserves precious platinum.
  • Ø  Favorable dimensional stability.
  • Ø  Corrosion resistance ensures durability with easy maintainability of the cathode to be protects.
  • Ø  Light weight, as well as favorable current distribution in electroplating.

Platinized Titanium anodes take advantage of the low consumption rate and high current density. Voltages in excess of 10 Volts will result in severe pitting of the titanium core causing premature failure. Exterior protection of ships hulls - anodes in the shape of plates, discs or strips

Platinized FRP insulated strip Anode with impressed current leads to protect the hull of the ships. Negative terminal which is connected to ship hull and positive terminal with impressed current anodes.

Underwater steel structures protection like wharves, jetties, sheet pile walls and piers. Usually rod type anodes distributed throughout the structure to be protected to give a good overall protective current distribution.

Change in the potential of an electrode as the result of current flow to or from that electrode. Also, a change in the potential of a corroding metal from its natural steady-state value, as a result of current flow. “Depolarization” is the reverse process of Polarization. Depolarization is sometimes referred to as "hypo polarization”.

Impressed Current Cathodic Protection systems are the ultimate solution for all corrosion problems to protect the metallic structure for long time and are recognized as a superior alternative to sacrificial anode systems which require frequent replacement. Impressed current cathodic protection systems are preferred by ship owners because they reduce fuel cost and maintenance.

ICCP (Impressed Current Cathodic Protection)anodes are controlled amount of DC current to submerged surfaces like underground oil wells using highly reliable mixed metal oxide anodes and zinc reference electrodes. This electrical current, constantly monitored and regulated by the system itself to prevent the electrochemical action of galvanic corrosion before it begins.

Platinized Titanium Rod are usually used in cantilever anode which is used for protecting pipeline internal, pump internal & condenser box internal for 30 years and more by applying DC current with transformer rectifier.

Normally titanium is well known for its high resistance to corrosion both water and chemical media. But titanium is the poor electricity conductor. So we use platinum/ MMO plating/Coating to increase the conductivity.

We Tiaano is the supplier of cathodic protection over 65 countries like Israel Electricity, Aramco etc., and owning the name created the regular customer for us.
