Why regular Cathwell service is essential for ICCP & MGPS/ICAF maintenance
Extending marine asset life and maximising your investment
Sun storms causing corrosion
Telluric current causing corrosion on buried pipelines
Levels of cathodic protection
Cathodic protection involves polarisation of a metal towards more reducing potentials
Inspection of ICCP for building foundations
Frequent site surveys important to maintain adequate protection
Pipeline integrity inspection
Assessment of corrosion protection for buried pipelines
Antifouling anodes in strainers
Antifouling anodes in the mud box lids to prevent fouling.
Dual-action antifouling & anticorrosion anodes
Cu anodes in pair with Al or Fe anodes to prevent fouling.
MasterCath® remote access system
MasterCath® is designed for remote operation of ICCP and MGPS/ICAF antifouling.
Building foundation protection
Cathodic protection can ensure that steel structures maintain its strength.
Electrolytic antifouling explained
Low concentration of copper ions prevent marine growth.
Marine fouling in seawater inlets
Marine fouling is an unwanted development of biological organisms.
Design lifetime of sacrificial anodes
The amount of anodes corresponds with the surface to be protected.
Aluminium vs. zinc anodes
Which to use; aluminium or zinc anodes in salt water environments?
Al or Zn anodes in ballast and cargo tanks?
Aluminium anodes have both technical and economical advantages over zinc.
Forms of corrosion
Here is explained 10 common types of corrosion, including galvanic corrosion and flow-assisted corrosion
CathSense® ICCP in rough conditions
Operation in extreme conditions make considerably demands on the ICCP system.
What is corrosion?
Corrosion is a process of degradation of metals and non-metals
Galvanic series
Galvanic series determines the electro potential and nobility of metals and metal alloys.
Cathodic protection explained
Principles of cathodic protection. How to stop corrosion
Dynamic copper dosing
Tuning the antifouling dosing according to the water flow saves cost and is more environmental friendly.
Range of corrosion protection
What sea cable length can be protected with only one cathodic protection system?
SPS of mobile offshore units
Mobile offshore units (rigs) are highly valuable assets, which require well designed and operated systems for cathodic protection.
Current leakage measurement
Effective measurement technique to detect undesirable connections.
Lack of isolation leads to stray current
Unwanted interconnections may lead to corrosion and reduce the control of cathodic protection.
ICCP or sacrificial anodes for buried tanks?
Cathodic protection systems with benefits and disadvantages.
How to test isolation joints?
Different measurements techniques can be used to verify the condition of isolation joints.
ICCP or sacrificial anodes?
Sacrificial anodes vs. ICCP for corrosion protection of harbour structrures.
Avoiding corrosion in box cooler sea chest
Proper box cooler arrangement and protection reduce the risk of severe corrosion.
Why grounding the rudder?
Lack of electrical/metallic connection between the rudder and the hull may result in spark corrosion.
Nothing concerns more than the c-word
Out of sight, out of mind should not be an expression for buried pipelines.
Buried steel pipeline protection
The answer is found in a 200 years old technique.
Cathodic protection – vital for oil and gas pipelines
Corrosion prevention is an essential part of asset-protection strategy.
Make sure your tank is not an anode
Accessories and connections can result in increasing risk of corrosion.
Reliable system follow-up
Well-structured system follow-up ensures effective maintenance of ICCP and MGPS/ICAF systems.
