Propeller Polishing
& Repair Services
Advanced Propeller Polishing Technology
MaxiDive utilizes a dedicated multi-stage propeller cleaning and polishing system designed specifically for non-ferrous propeller materials. Our polishing tools are equipped with diamond polishing disks, enabling us to achieve a Rupert scale “A” finish across all accessible propeller surfaces.
The polishing process is performed in controlled stages to ensure uniform surface smoothness without excessive material removal. This method significantly reduces surface roughness while preserving blade geometry and structural integrity.
What Our Propeller Polishing Service Includes
-
Multi-stage micro polishing of all propeller blade surfaces
-
Use of diamond polishing disks to achieve Rupert scale “A” finish
-
Detailed written inspection report with photographic documentation
-
Identification and documentation of surface damage, cavitation marks, or abnormalities
-
Propeller trimming and static balancing, where applicable
All work is performed underwater, allowing vessels to remain operational without dry-docking.
Understanding Propeller “Super-Polishing”
Many commercial diving companies offer propeller polishing to Rupert scale “A”, equivalent to approximately 0.65 microns surface roughness. However, because propellers are typically manufactured from non-ferrous alloys, precise roughness measurement underwater is technically impractical.
As a result, surface quality is verified through visual comparison against Rupert reference plates, combined with professional inspection by experienced operators.
MaxiDive applies a true multi-stage super-polishing process using the latest materials and tools from 3M, ensuring consistent surface refinement beyond basic single-stage polishing methods commonly used in the industry.
Why Propeller Surface Quality Matters
A properly polished propeller provides measurable operational benefits:
-
Reduced fuel consumption
-
Improved vessel speed and thrust efficiency
-
Lower vibration and mechanical stress
-
Reduced risk of cavitation damage
-
Extended service life of propulsion components
Maintaining minimal surface roughness is one of the most cost-effective ways to improve overall vessel performance.
Experience, Quality, and Compliance
MaxiDive’s propeller polishing operations are carried out by commercial divers with over ten years of hands-on experience in underwater ship maintenance. All procedures follow industry best practices and vessel-class requirements, ensuring consistent, reliable, and verifiable results.
Each project is completed with full documentation, providing transparency for shipowners, fleet managers, and technical superintendents.
MaxiDive delivers professional propeller polishing and repair services that enhance propulsion efficiency, reduce operating costs, and support reliable vessel performance throughout Thailand’s busiest ports.
