Propulsion & machinery
A ship earns its money through the propeller. We keep the propulsion line and its auxiliaries working: propeller and blade repairs, shafting, stern tube and seals, rudders, pumps and valves.

Questions
04 / 05Q.01Why polish a propeller?
Roughness on the blades costs efficiency and therefore fuel. Polishing restores a smooth surface; leading-edge damage is dressed or repaired so the blades work as designed.
Q.02When are rudder clearances measured?
At every docking, and whenever vibration or steering trouble suggests wear. The readings are compared with the limits for the bearings.
Q.03Can propeller work be done afloat?
Some of it, such as blade polishing, can be done afloat by specialised diving teams; removing the propeller or the rudder needs a dock.
