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.
