The stainless steel ring in the propeller tip region protects the tunnel against cavitation damage. The oil lubrication system with oil level sensor (to be installed by the shipyard above waterline) protects the seals against water ingress. Galvanic cathodic protection (CP) is calculated and installed to protect the systemfor up to 5 years. Options: Impressed current cathodic protection (ICCP) instead of anodes for longer life and reduced resistance in the tunnel. Anti-suction tunnel (AST) — a second smaller tunnel installed behind the bow thruster to increase the thrust during cruising. A holding brake to prevent propeller windmilling and noise during passage is recommended. Besides electric motor brakes, hydraulic, pneumatic and electrically driven disk brakes are available for new builds and retrofits.
