GALVANIC CORROSION INSPECTION
Is your yacht protected correctly?
Are your through hull fittings, prop shafts, propellers , stern drives or sail drive slowly or quickly being eaten away by galvanic or electrolytic action below the water line while you lovingly look after the parts you can see above the water line.
Does your yacht have the required protection for the area it is situated in. Remember that sea temperature, salt water, fresh water, brackish water effect the size and type of the required sacrificial anodes. Wooden hulls can be damaged by to much protection.
Remember that while your yacht may be fully protected and correctly fitted out the vessel next to you and the electrical mains power facility on the dock may not be and can cause server damage very quickly due to electrolytic action.
We offer Peace of mind
We have the test equipment to check to see if the vessel is correctly protected against galvanic & Electrolytic corrosion while afloat and on a particular mooring.
Corrosion surveys analysis is performed to see if the vessel’s underwater metal fittings are being adequately protected against galvanic corrosion by the existing anodes and bonding protection systems that are currently in place. This analysis will also check for any stray current (also referred to as electrolysis) that may be occurring around the vessel or coming from the vessel itself with the use of a commercial grade corrosion meter.
A determination can be made if the vessel’s underwater metal fittings and parts are being properly protected, are freely eroding or are being overprotected. All tests associated with this survey are non-destructive and will be done while the vessel is afloat.
Upon completion of this testing, a written report is given describing the tests carried out and any recommendations required.
We can provide advice for corrosion control equipment such as fail safe galvanic isolators, hull potential meters, reference electrodes, and propeller shaft brushes.
