Grit-Free Surface Preparation Below the Waterline
Engineered for underwater environments, diving operations, and offshore maintenance, delivering controlled surface conditioning even in demanding subsea conditions.
Below the surface
When corrosion protection needs to extend below the surface of the sea, precision, safety, and reliability become even more critical.
“Grit-free preparation, controlled even below the waterline.”
Water pressure
Managing buoyancy and pressure effects at depth.
Limited visibility
Operating in murky or restricted subsea environments.
Environmental risk
Preventing contamination in sensitive marine ecosystems.
Operational constraints
Meeting strict diving campaign and ROV requirements.
Hydraulic power, underwater integrity
The Bristle Blaster® Subsea is a hydraulic underwater device with a unique water drive. Connected via a single, neutrally buoyant high-pressure hose, it creates a controlled, inspectable surface profile below the waterline, without grit or containment. Topside, the same principle runs on the Bristle Blaster® range.
