Bristle Blasting for Underwater Corrosion Protection: the 2016 Study
A 2016 German study examined bristle blasting as surface preparation for corrosion protection in underwater applications — the research base behind subsea mechanical preparation.
Underwater, almost every conventional preparation method fails or becomes prohibitively complex. This page summarizes the German 2016 study (with English context) on bristle blasting as surface preparation for corrosion protection in underwater applications.

What does it cover?
The study investigates rotary bristle preparation for subsea corrosion-protection work: how the process performs underwater, and what surface condition it delivers for subsequent protection systems. The original paper is in German; the method and findings are summarized here in English.
Why does it matter?
Splash zones and subsea steel are among the most corrosion-critical and least accessible surfaces in industry. Research supporting mechanical preparation underwater is the foundation for tools like the Bristle Blaster® Subsea, now in service on offshore assets.
The research line continues: Fraunhofer IGP is developing ROV-based underwater coating repair around the Subsea Bristle Blaster® — 2026 conference presentation (PDF, German) with measured profiles and ISO 4624 adhesion results.
