SLEIPNER PROPELLER ANODE TEN01052

Function and technical context

The Sleipner TEN01052 propeller anode is a cathodic protection element specifically designed to be mounted on the propeller of Sleipner propulsion systems, acting as a galvanic sacrifice against electrolytic corrosion that affects metals submerged in salt, brackish or even fresh water with dissolved minerals. Its function is to attract galvanic corrosion towards itself, protecting more valuable metal structures such as the propeller shaft, nozzle, hub and propeller blades. Without adequate cathodic protection, electrolytic corrosion can rapidly degrade propulsion components, causing efficiency losses, vibrations and structural failures that require costly replacements. The reference TEN01052 uniquely identifies this anode within the Sleipner catalogue, guaranteeing that the geometry and alloy used are appropriate for optimal fit and protection in the thrusters for which it was designed.

When to replace this part?

Propeller anodes should be inspected at least at the beginning and end of each nautical season; The general rule is to replace them when they have lost approximately 50% of their mass, since below that threshold the cathodic protection is insufficient. Symptoms of a depleted or missing anode are manifested by visible pitting and erosion on the surface of the propeller hub, propeller shaft or nozzle, as well as accelerated corrosion of adjacent submerged metal surfaces. Changing the anode preventively at each annual tune-up is the most economical measure to avoid propeller repairs or shaft replacement due to advanced galvanic corrosion.
