Corrosion problems are more complex now than they have ever been.

Increasing complexities of electrical and electronic systems on board is one of several factors that can lead to expensive corrosion and paint coating issues.

More awareness of corrosion problems and the need for them to be identified correctly has created a demand in the industry for specialist corrosion surveys to international standards.

Marine Cert technicians are trained and internationally certified. Using the latest technology and equipment we gather data from the vessel together with a time line and environmental factors to provide detailed reports in accordance with American Boat and Yacht Council, ABYC E-2,E-11 standards for maintenance and protection against corrosion.

To mitigate the effects of corrosion we make recommendations on vessel bonding, anode types and cathodic protection. We recommend follow up testing after initial survey is performed to ensure the vessel test results remain within safe parameters. It is prudent to keep a regular log of these results to monitor any changes that may occur.

Marine Cert specialises in providing certified testing and advise on all forms of metallic corrosion control:

  • Marine Structure Surveys
  • Vessel Corrosion Surveys
  • All Construction Types
  • Electrolytic Corrosion
  • Material Selection and Design
  • Cathodic Protection
  • Scarificial Anode Selection
  • Vessel Bonding Systems
  • Galvanic Isolator Options
  • Impressed Current and Monitoring Systems
  • Vessel bonding systems

Testing can be done independently or added on to your Marine EWOF inspection.

Q: When should I get a Corrosion Survey?
A: A good time to do a survey is before coming out of the water for the annual antifoul and/or maintenance, this gives a good base reading that can be monitored for future surveys.  Also a good idea to have a Corrosion Survey and an Electrical Condition Report as a part of your pre-purchase checks on a vessel.
   
Q: Why should you have a Corrosion Survey on your boat?
A: To assess how your vessel is currently placed and protected against electrolysis and galvanic corrosion, and to ensure you do not have any expensive damage accruing to your valuable asset. Corrosion can affect the safety, structure and the performance and speed of the vessel.
   
Q: How often should I get a Corrosion Survey done on my boat?
A: Once you have had your initial full Galvanic Survey, periodic check should be done to monitor any changes. Best practice would be before every antifoul and replacing the zincs on your vessel. Referencing back to the original survey report is the best way to ensure no corrosion is taking place on your vessel
   
Q: What do I do if I notice corrosion on my boat while it’s out of the water?
A: Contact Marine Cert before any repair work commences, this can be critical in determining the cause of the issue.
   
Q: Should I photograph corrosion damage on my boat?
A: If Marine Cert cannot see your vessel before work commences, take as many detailed high resolution photographs as possible.
   
Q: Does my boat need to be in the water for a Corrosion Survey?
A: YES, for an accurate survey. Limited readings can be taken out of the water but to complete the full survey the vessel will need to be in the water.
   
Q: How do you test for Corrosion?
A: Marine Cert technicians are trained and internationally certified. Using the latest technology and equipment we gather data from the vessel together with a time line and environmental factors to provide detailed reports in accordance with American Boat and Yacht Council, ABYC E-2,E-11 standards for maintenance and protection against corrosion
   
Q: What damage can corrosion do to my boat?
A: Depending on the type of Corrosion it can be slow erosion of fittings through to rapid, aggressive depletion of material within days. It can affect the safety, structure and the performance and speed of the vessel.
