In-water Propeller Polishing

In-water Propeller Polishing – The Solution to Enhance Ship Propulsion Efficiency

In-water Propeller Cleaning is one of the smartest maintenance decisions a shipowner can make. By removing marine growth and polishing the propeller while the vessel remains afloat, this specialized Marine Service restores lost efficiency, reduces fuel consumption, and protects the entire propulsion system — without the need for dry-docking.

What is In-water Propeller Cleaning and Why Does It Matter?

Over time, barnacles, algae, and other marine organisms attach themselves to the propeller blades. Even a thin layer of fouling increases surface roughness, disrupts water flow, and forces the engine to work harder. The result? Higher fuel bills, reduced speed, increased vibration, and greater stress on the shaft and bearings.

In-water Propeller Cleaning combined with professional polishing solves this problem quickly and effectively. Certified divers use specialized tools to clean and polish every blade and the hub, bringing the propeller surface back close to its original smooth condition. The benefits are immediate:

  • Improved propulsion efficiency
  • Lower fuel consumption
  • Reduced vibration and noise
  • Less wear on the shaft line and bearings
  • Faster return to optimal sailing performance

The Propeller – The Heart of the Ship’s Propulsion System

The propeller is the final and most critical link in the propulsion chain. It converts the engine’s power into thrust. When the propeller surface is clean and smooth, the entire system operates at peak efficiency. When it is fouled, every part of the propulsion system suffers — from the main engine to the stern tube bearings.

Keeping the propeller in top condition is not just a technical task; it is a direct investment in the vessel’s reliability and profitability.

Better Propulsion Performance Means Real Business Advantages

For vessels operating on long international routes, the advantages of a well-maintained propeller are clear and measurable:

Economic advantage: Even a small improvement in propeller efficiency can save dozens or even hundreds of tons of fuel per year. The cost of In-water Propeller Cleaning is quickly recovered through lower fuel bills.

Environmental advantage: Lower fuel consumption means reduced CO₂ and greenhouse gas emissions, helping ships meet increasingly strict international environmental regulations.

Time advantage: Ships maintain their designed speed more easily, avoid unnecessary delays, and spend less time out of service. Performing the work underwater also eliminates the need for costly and time-consuming dry-docking solely for propeller cleaning.

We recently completed this hotwork project on a 7-hold vessel at Van Phong Anchorage, Vietnam, ensuring all ABS requirements — including the approved repair plan, welding procedures, certified welders, and material certificates — were strictly followed with zero impact on the vessel’s schedule.

Importance of Steel Works for Deck Integrity and Fire Safety

Deck plate strength and the fire main system are essential for structural safety and emergency response on cargo vessels. On a 7-hold ship, localized corrosion or deformation of the deck plate can affect hatch coaming integrity and safe cargo operations, while a compromised fire-fighting pipeline poses a direct risk to onboard safety. VietNam Shiprepair’s expert Steel Works restore both the structural reliability of the deck and the full functionality of the fire main, fully meeting ABS class requirements.

Professional Steel Works Process under ABS Supervision

VietNam Shiprepair executed the following controlled process for the deck plate and complete fire main replacement at Van Phong Anchorage:

  • Erected safe staging and implemented comprehensive hotwork safety measures, including fire watch, gas-free certification, and fire protection systems.
  • Conducted joint inspection with the ABS surveyor to determine the exact scope of steel renewal and fire main replacement.
  • Submitted and obtained ABS approval for the repair plan, Welding Procedure Specification (WPS), welder qualifications, and material certificates.
  • Cut out the damaged deck plate section and removed the entire on-deck fire main pipeline.
  • Installed new ABS-approved steel plate and certified fire main pipes.
  • Performed welding by ABS-certified welders using approved procedures.
  • Carried out Non-Destructive Testing (NDT), including Ultrasonic Testing (UT) and Penetrant Testing (PT), on all welds.
  • Conducted pressure testing of the renewed fire main system under ABS witness.
  • Applied anti-corrosion coating and completed final visual and dimensional inspection.
  • Obtained final ABS surveyor endorsement for the completed Steel Works.

This systematic approach ensured full class compliance while maintaining strict control over hotwork risks and quality.
