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

    Professional In-water Propeller Survey in progress
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.

Importance of Under Water Repairing for Watertight Integrity

Absolute watertight integrity is a fundamental safety requirement for any vessel. When a hull puncture allows seawater to enter a ballast tank, the vessel’s stability, structural safety, and operational readiness are immediately compromised. On a Panamax bulk carrier, such an incident can quickly escalate into a serious safety and commercial risk. Professional Under Water Repairing by VietNam Shiprepair restores the watertight boundary without the need for dry-docking, enabling the vessel to continue safe operations while fully complying with ABS Class requirements.

Professional Under Water Repairing Process under ABS Supervision

VietNam Shiprepair executed the following controlled process for the emergency underwater repair at PTSC Dung Quat Port:

  • Mobilized a certified diving team approved by both the shipowner and ABS Class.
  • Conducted a detailed underwater survey to precisely locate the puncture, document the damage with photographs and video recordings, and assess the extent of the crack.
  • Developed and submitted the repair plan for ABS approval, including welding procedures, welder qualifications, and material certificates.
  • Drilled two 15 mm diameter holes at both ends of the crack to prevent further propagation.
  • Fitted and welded an 1200 × 300 × 10 mm doubler plate on the exterior of the hull using ABS-approved welding procedures, certified welders, and approved materials.
  • Performed a thorough leakage check to confirm that water ingress into Ballast Tank No. 4 had been completely stopped.
  • Obtained final ABS surveyor endorsement for the completed Under Water Repairing.

This systematic underwater approach restored full watertight integrity in the shortest possible time without requiring dry-docking.

A hull puncture that allows seawater into a ballast tank poses an immediate threat to safe operation and can lead to costly delays. VietNam Shiprepair’s Marine Services focus on rapid mobilization of certified divers, precise underwater execution, and close coordination with ABS Class so that critical Under Water Repairing is completed efficiently while fully satisfying class and safety requirements.

Importance of Urgent Steel Works for Tank Top Integrity

The tank top plating forms a critical structural and watertight boundary between the cargo hold and the underlying ballast tanks. On a Panamax bulk carrier, any puncture caused by falling cargo immediately compromises this separation. Failure to restore full watertight integrity can lead to cargo contamination, ballast system issues, and serious navigational risks. In addition, prolonged delays create significant commercial losses for all parties involved. Professional Steel Works by VietNam Shiprepair restore structural strength and complete isolation of the ballast tanks, ensuring safe navigation and cargo protection while minimizing downtime.

Professional Steel Works Process under NKK Class Supervision

VietNam Shiprepair executed the following controlled process for the tank top plate replacement at Quy Nhon Anchorage:

  • Conducted a detailed joint inspection with the NKK surveyor to assess the extent of the puncture and define the precise renewal area.
  • Submitted and obtained NKK approval for the repair plan, Welding Procedure Specification (WPS), welder qualifications, and material certificates.
  • Erected safe staging and implemented full hotwork safety measures inside the cargo hold.
  • Cut out the damaged tank top plating in the affected area.
  • Fitted and installed new NKK-approved steel plate matching the original thickness and grade.
  • Performed welding by NKK-certified welders using approved procedures.
  • Carried out Non-Destructive Testing (NDT), including Ultrasonic Testing (UT) and Penetrant Testing (PT), on all welds.
  • Conducted watertight testing to confirm complete isolation between the cargo hold and ballast tanks.
  • Applied anti-corrosion coating and completed final visual and dimensional inspection.
  • Obtained final NKK surveyor endorsement for the completed Steel Works.

This systematic approach restored full structural and watertight integrity in the shortest possible time.
