Waterjet services for shipyards and marine operators
Dezu prepares marine steel with high pressure water — hulls and decks by VertiDrive magnetic crawler and hand lance, tanks and fuel-service steel by water methods that carry no spark. Proven at the US Navy standard: deck anti-skid removal on USNS Big Horn and USNS Yukon, 2022.
What does Dezu do for shipyards and vessel operators?
Surface preparation and cleaning on marine steel: hull and deck coating removal with high pressure water, deck anti-skid (ASA) removal — delivered on USNS Big Horn and USNS Yukon, two US Navy vessels — plus vessel tank cleaning and spark-free cold cutting for steel in fuel service.
How do the VertiDrive crawler robots work?
VertiDrive magnetic crawlers grip the hull and strip coating in continuous passes under remote control — faster and more uniform than staged hand work, with crews off the ropes. Dezu is the exclusive Philippine distributor: we operate the robots on contract work, rent them, sell them, and train your crew on them.
Why prepare marine steel with water instead of grit?
No spent abrasive on the deck or in the harbor, no dust cloud over the yard, and soluble salts washed off the steel — the contaminant grit blasting leaves behind that shortens coating life. Cleaner surveys, repaints that last, simpler environmental handling.
