Marine Protection Systems know that the subject of cathodic protection is considered complex and confusing by many boat owners. The information contained here will help you understand corrosion and protection from corrosion and help you select the right combination of solutions for best results.
Individual vessel corrosion control is the responsibility of the owner. However in accordance with AS/NZS 3004.2008 the marina operator is required to make certain information available to its members. This document explains that information.
Cathodic Protection can be a complex subject. In this document you can learn some of the factors that could effect cathodic performance.
Galvanic corrosion is the basic term given to the reaction between different metals in the same electrolyte. This document explains the principals of that reaction and why it is such a common occurance for vessel owners.
Cathodic Protection is the process in which metals and composite metals can be used as sacrificial anodes to protect other metal from galvanic corrosion, Electrolysis and Wood Rot. Cathodic protection in the marine environment refers to protecting the vessels drive, steering and other submerged metal parts using a block of Maddox, Zinc, Aluminium or Magnesium as a sacrificial anode.
When it comes to anodes, less is more. If you could take all the different anodes off your boat in favour of just one that does a better job, why wouldn’t you? Find out how it is possible here.
A shore power connection at your marina is capable of significantly increasing your chances and severity of galvanic corrosion issues. This document will explain the meaning of “stray earth current” the effects it will have on your vessel and how it can be stopped.
A Vessel Bonding System is the circuit that carries the mV potential of submerged metal parts to the anode and BUS bar earth. This document contians information that will ensure your Vessel Bonding System is as effective as possible.
A significant number of vessels at marinas around the world are over protected and as such could be causing as many problems under water as a vessel with no cathodic protection. This document explains the damaging effects of over protection.
International standards offer some guidance as to the recommended mV (millivolt) potential of an effective anode. That information available here will help you select the correct anodes for your vessel.
The MPS Electrolysis Blocker has been rigorously tested to the highest international marine standards including, ABYC, ISO and AS/NZS.
Many countries have different regulations concerning importing and installing electrical equipment and it may be illegal and/or dangerous to import or install a device not tested and approved. Check with your local standards authority.
Instructions for installing the MPS Shaft Grounding Strap which will greatly assist in reducing any potential corrosion from the shafts and propellers.
Installing the Maddox anode is quick, inexpensive and immediatly effective. This document contains tips for retro fitting a Maddox anode to any size vessel and ensuring it is operating at its peak performance.
