Sacrificial Anodes System

image
In cathodic protection, pieces of metal (known as Sacrificial Anode) are linked electrically to the ship’s hull. These anodes, are made of metals more reactive than the material used for the ship’s body and systems. As such, they will corrode in place of the ship’s body and systems while the ship stays protected, giving rise to the name ‘Sacrificial Anodes’.

Sacrificial anodes are also deployed on:
  • subsea strcutures
  • pipelines
  • platforms
  • wind turbine foundations
  • Zero risk of interference
  • monopiles
  • wave and tidal generators
  • quay and harbour walls
  • jetties & pontoons
  • dock gates
  • ships and boats hulls
  • ballast
  • grey and potable water tanks
  • power station intake screens
  • storage tanks
To sum it up, Sacrificial Anodes can be effectively deployed wherever there’re metal parts partially or fully submerged in seawater, to protect these parts from marine corrosion; Cathodic Protection.
Cathodic Marine specializes in manufacturing large platforms, bracelet and flush mounted Anodes, in sizes up to 4 tonnes (4000 KG), in line with the highest standards and quality of Marine and Offshore industries.

Advantages of using Sacrificial Anodes

There’re a multitude of benefits associated with the use of Sacrificial Anodes, the main ones being:

  • Capacity to last and provide effective Cathodic Protection for up to 25 years
  • No maintenance required
  • Very high reliability
  • No modifications on hull interior, and no hull penetrations
  • Zero risk of interference
  • Compatibility with other CP systems on subsea equipment
  • Lower overall life cycle cost

Advantages of using Sacrificial Anodes

inc Anodes are cast from a high purity zinc alloy to ensure an even corrosion pattern, reliable electrical efficiency and long working life. The zinc alloy is in accordance with the US MIL A-1800H specifications.
