Removing Paint from Ship Hulls

Efficient Paint Removal of Ship Hulls with High-Pressure Water Blasting

Fast and effective removal of algae and shells WOMA high-pressure waterjetting technologies can do much more than just clean ships. As well as cleaning, paint removal is also required to enable the subsequent application of a new corrosion projection. Ship renovations is vital as ships need to be cleaned for re-painting and also for inspections. This is a vast operation due to the sheer size of the ships hull, care must be taken not to damage the structure of the ship. Using high-pressure water jetting technologies and specific nozzles, paint, rust, and corrosion can be removed with ease – leaving behind a clean surface for inspection for further application.

Treatment with water at high pressure enables high area performance in a short time and lets surfaces look like new. The substrate is optimally prepared at the same time. Completely without chemicals. Completely without blasting material. Surface cleaning and renovation in one step and with minimum disposal costs. Conventional sandblasting methods for cleaning ship hulls are very contaminant-laden and environmentally harmful. For environmental reasons and due to the high disposal costs of contaminated blasting material, sandblasting is being increasingly replaced worldwide by ultrahigh-pressure jet technology. The result is convincing in all cases: high cleaning quality, high effectiveness even in difficult to reach areas, high cleaning quality, and a high degree of protection for the user and the environment.

WOMA water tools for water blasting applications are the optimum solution for paint removal of ship hulls.

  • Surface preparation prior to coating application.
  • Removal of deteriorated protective coating systems.
  • Spot repair on partially deteriorated coating systems.
  • Selective paint stripping.
  • Cleaning and descaling of weld seams.
  • Emission-free surface preparation on ship hulls and superstructures.
  • Large-scale surface preparation with mechanically guided tools.
  • Cutting of steel.
  • Cutting of internal pipe systems.


  • It significantly reduces the amount of deposit. Compared to grit blasting, up to 98 percent less solid waste material needs to be considered. Hence customers save large amounts in disposal costs.
  • It considerably reduces the time required for cleanup because no grit needs to be collected and removed at the end of the job. Thus, customers save hundreds of hours of time and labor.
  • It is dust-free, allowing different trades, to work side by side. Moreover, dust-sensitive areas can be maintained while the waterjetting is carried out. Therefore, customers save expensive time in drydocks.
  • It generates very low impact forces on surfaces; working almost vibration-free. No substrate material will be removed. Hence a customer avoids damage on their structures.
  • It is used in rainy or windy environments. Hence the customers are not dependent on weather conditions and can readily schedule work with high reliability.
  • It ensures excellent adhesion conditions between substrate and coating even if flash rust is present.
  • It exposes the original profile. In contrast, grit blasting reduces the original profile height due to particle impact. Thus customers offer an excellent surface profile to the painter giving a good mechanical bond between substrate and coating.
