Electrolysis Protection
Consequences of electrical leaks
- When metals are in an electrolytic couple situation (contact with sea water or polluted coolant + direct contact or by any conductor) a current is produced and one of the 2 metals is destroyed.
- This current is low and manageable with conventional anodes.
- If an additional current intervenes, the phenomenon accelerates and can quickly become unmanageable.
- As it is almost impossible to remove the contacts, it is essential to avoid leaks.
- Fix any discovered problems.
Equipment used
- A multimeter
- An anode that can be immersed next to the boat
- A reference anode (calomel anode)
General course of the expertise
- Duration: at least half a day.
- Ship afloat.
- Continuity test: Search for the possibility of current flow to the immersed parts of the motor.
- Potential test: Search for potential differences that could create electric currents (boat disconnected from the dock then boat connected to 220 V).
General terms and conditions of the expertise
- A few days before the expertise a Mandate of Expertise is sent by e-mail confirming the particular conditions (amount, date, place, time of the appointment …) and all the general conditions for final agreement.
- The above description is a proposal that can be modified according to the technical and/or safety conditions encountered during the examination and considered as fixed by the applicant.
