Ship Repair Paint Removal System | Dry Dock & Hull Coating Stripping

Fedjetting ultra-high pressure waterjet systems deliver asafe, efficient, eco-friendly way to remove marine paint, coatings, rust and foulingfrom ship hulls, tanks, decks and offshore structures. Our non-abrasive, dust-free process preserves steel substrate integrity, achieves high-quality surface standards, and fully complies with global marine environmental regulations.

UHP Waterjet Cleaning Systems for Shipbuilding

Our magnetic climbing robot is engineered for large-area marine surface treatment and supports fully wireless remote control. With strong magnetic adhesion, it works stably on vertical, overhead and horizontal steel surfaces without scaffolding or aerial lifts. Featuring a working width of 1.5m and travel speed up to 10m/min, this lightweight unit can be set up in just 10 minutes and pairs with a vacuum recovery system to contain water and residues, delivering efficient, clean and safe operation for shipyards and offshore sites.

Waterjet Solution

Main Equipment Configuration

The high pressure pump unit delivers stable water output and runs durably for long-term operation under harsh marine conditions. The mobile cleaning unit features a compact structure, easy to move around docks and ship cabins for multi-area work. Complete safety mechanisms including pressure protection, emergency stop and leakage monitoring are equipped to fully safeguard operators.

Hydroblast vs. Sandblast

The surface profile of steel directly determines the long-term performance of new paint coatings. Fedjetting’s hydroblast technology preserves the original steel structure and removes contaminants effectively, while traditional sandblasting can alter the surface profile and trap fouling, leading to premature coating failure.

Hydroblast (Recommended)

Ultra-high-pressure water cleaning maintains the original steel profile and removes all contaminants without creating crevices or hidden areas. This ensures the new coating bonds directly to the clean surface, eliminating the risk of trapped fouling under the paint layer and extending the service life of marine coatings.

Sandblast (Traditional Method)

Sandblasting reshapes the steel surface, creating sharp peaks and deep valleys that trap residual fouling and contaminants. These hidden contaminants continue to corrode the steel beneath the new paint, leading to early coating blistering, peeling and failure, which increases maintenance costs and vessel downtime.

Why Choose UHP Waterjet Over Traditional Methods

Substrate Safe

Removes old paint, anti-fouling layers and rust without scratching, pitting or altering steel surface profile. Optimizes adhesion for new coatings and extends overall service life of vessels.

Premium Surface Quality

Consistently reachesSC-2 surface standardin a single pass. Effectively eliminates chloride, ferrous ions and residual contaminants to meet strict marine coating specifications.

Eco-Friendly Operation

No abrasive media, no airborne dust and no chemical additives. Waste water can be collected, filtered and recycled, fully conforming to international maritime environmental protection rules.

Superior Productivity

Working efficiency is up to60% higherthan conventional sandblasting. It cuts labor input and greatly shortens ship docking and maintenance cycles.

Wide Adaptability

Suitable for all marine steel structures, including curved hull surfaces, narrow compartments and complex structural parts.
