Water Jetting Systems for Ship Surface Preparation | Efficient, Eco-Friendly Cleaning Solutions
Water jetting systems for ship surface preparation are essential for maintaining the integrity, safety, and aesthetic appeal of ships. By using high-pressure water jets (up to 2800 bar), these systems effectively remove rust, paint, corrosion, marine growth, and other contaminants from ship surfaces. The result is a clean, smooth surface that is ready for painting, coating, or repair.
Our water jetting systems are designed for safe, eco-friendly, and cost-effective surface preparation, ensuring that ships remain in optimal condition for both commercial and military applications.
How Water Jetting Systems Work for Ship Surface Preparation
Water jetting systems use high-pressure water to clean and prepare ship surfaces effectively. The basic components of a water jetting system include:
How It Works
High-Pressure Pump: Generates the necessary pressure (typically from 500 bar to 2800 bar) to propel water through the nozzle
Nozzles: Rotary or fixed nozzles that direct water in a concentrated stream across surfaces to break up and remove contaminants
Flexible Hoses and Lances: Reach difficult-to-access areas like ship hulls, underwater surfaces, and deep spaces
Control System: Allows the operator to adjust water pressure and flow rate based on the cleaning requirement
Water Recovery System (Optional): Collects and filters the used water for disposal or reuse, ensuring environmental compliance

- Hose Length: Flexible hoses up to 100 meters
- Water Recovery: Optional systems to collect and filter used water
- Control System: Manual or automated control for precise water pressure management

Applications of Water Jetting Systems for Ship Surface Preparation
Water jetting systems are versatile and suitable for various ship maintenance tasks:
Hull Cleaning: Removes marine fouling, algae, and barnacles that accumulate on the hull
Rust and Scale Removal: Cleans the steel surfaces of ships, removing rust and corrosion from hulls and other metal parts
Deck Cleaning: Prepares the deck surface for coatings and repairs by removing dirt, oil, and old paint
Underwater Cleaning: Cleans underwater areas of ships while in dry docks or floating docks
Surface Preparation for Painting and Coating: Provides a clean surface for better adhesion of protective coatings, primers, and paints
Marine Equipment Cleaning: Prepares other ship equipment, such as pipelines, tanks, and reactors, for maintenance or servicing
Advantages of Using Water Jetting Systems for Ship Surface Preparation
