Propeller Polishing — Efficiency Begins Underwater
Certified commercial divers restoring your vessel’s performance through professional underwater propeller polishing across Scandinavia, Worldwide - Smooth propellers. Efficient voyages
Professional Propeller Polishing Services in Scandinavia and Worldwide
At Delta Marine Scandinavia AB , we specialize in underwater propeller polishing — helping shipowners and operators reduce fuel consumption, improve speed, and extend the life of their propulsion system.
Our certified commercial divers use class-approved polishing tools to remove marine growth, oxidation, and micro-corrosion from the propeller blades, ensuring a smooth, mirror-like finish. Every project is carried out underwater, allowing your vessel to remain fully operational without costly dry-docking.
Whether you operate a cargo ship, tanker, cruise vessel, or offshore platform, our propeller polishing service restores peak performance while meeting the highest safety and environmental standards.
Why Propeller Polishing Matters
Even a thin layer of fouling or roughness on propeller blades can increase fuel consumption by up to 10–15%, causing unnecessary costs and higher emissions. Regular propeller polishing helps you:
- Restore full thrust and propulsion efficiency
- Reduce vibration and noise levels
- Lower CO₂ emissions and operational costs
- Protect the coating and extend propeller lifespan
- Maintain class compliance and vessel performance reports
A clean, polished propeller doesn’t just save fuel — it keeps your vessel performing at its designed potential.
Our Propeller Polishing Process
Every project starts with precision.
- Initial Inspection: Divers perform an underwater video survey to assess the propeller’s condition.
- Cleaning & Preparation: Removal of marine growth and debris using soft brush or cavitation tools.
- Polishing: Progressive polishing using multi-grade abrasive pads to achieve a high-shine surface.
- Quality Control: Surface roughness measured and verified against ISO standards .
high- quality finish, specifically Rupert Scale A grade, which corresponds to a surface roughness of approximately 0.65 microns. - Final Reporting: Before-and-after images, video documentation, and written service report provided within 24 hours.
We follow class-approved standards (DNV, ABS, Lloyd’s Register) and use environmentally friendly equipment to minimize marine impact.

FAQ
Typically every 3–6 months, depending on vessel activity and water conditions. Regular polishing maintains optimal propulsion efficiency.
Yes. Our divers can perform the service safely while the vessel is moored or anchored, following all port and environmental regulations.
No. We use class-approved polishing pads with controlled grit levels to achieve a smooth finish without removing excess material.
Savings vary, but vessels often experience 5–15% lower fuel consumption due to reduced drag and improved thrust.
Yes. We deliver a full photo/video report and written summary for class compliance and operational records.
Absolutely. We have the right abrasives and techniques for all common marine propeller materials. Absolutely. We have the right abrasives and techniques for all common marine propeller materials.
