ProAnode extends thruster life

Schottel ProAnode

The anode’s position in the cross-section of the nozzle tail shields it from harm

The first Schottel Rudderpropeller incorporating the recently developed anti-corrosion ProAnode will be used to extend the life of the thruster.

The anode’s position in the cross-section of the nozzle tail shields it from harm and contributes to the optimal hydrodynamic flow of the nozzle. Operational benefits include reduced flow interference, resulting in fuel savings, reduced operating costs and greater efficiency.

The removal of the anodes from the outside surface of the nozzle prevents them from being knocked off by flotsam, such as wood, ice or ground contact.

Loss of the anodes is usually only discovered during maintenance downtime, by which time corrosion might already have become a problem.

Integrating an anode into a nozzle depends on the nozzle’s diameter and the anode’s material. If possible, the anodes can provide up to five years cathodic protection against corrosion and reduce the need for additional anodes for the hull or other thruster parts.

The Rudderpropeller was manufactured in Doerth, Germany.
