The Tool That Improves Productivity and Outcomes in Shipyard Operations

High pressure air power creates high friction which causes stress to parts, shears substrate material, creates areas of heat stress, and embeds corrosion causing material deep into surfaces. It’s also hard to control and it’s dangerous for workers and the environment. Dry abrasive blasting (sandblasting), UHP hydrojetting and many types of slurry blasting are powered by high pressure.

  • Dry abrasive blasting in a marine environment essentially requires creating a dry desert environment in a humid coastal area to be successful. Extra steps to monitor and remove humidity and prevent chlorides in the air from contaminating surfaces and clogging equipment are prone to failure. Fighting against Mother Nature is a losing proposition.

  • Frustrations with dry abrasive blasting led marine operations to become among the first try UHP hydrojetting and slurry blasting. Insufficient control, difficult and inconsistent settings, pressure drops, high breakdown rates, equipment repair and maintenance nightmares and irritatingly frequent clogged valves are but a few of the issues that impacted productivity, and ultimately, applicability of the various high pressure wet methods.

  • Due to high pressure, safety remained an issue. Lacerations, kickback and vibration hurt workers. Encrustation of PPE, substrates and equipment require additional rinsing and drying time. Trading the problem of truckloads of dry grit for truckloads of water containing toxic coatings and treatments to be properly contained and disposed didn’t make the process any easier.

  • Finally, low pressure vapor blasting methods were introduced about two decades ago as a method to mitigate many of these issues. T

he number of shipyards choosing to adopt vapor blasting continues to rise in the number of shipyards and facilities as a “go-to” method for hull maintenance led day-to-day marine maintenance operations.

  • However, not all vapor blasting equipment is alike. Most use outdated slurry blasting technology. As such, they suffer from the same high breakdown and failure rates of slurry blasting. What some manufacturers designate as a “vapor blaster” cannot be considered true vapor blasting but rather a hybrid wet/dry or slurry (induction) machine or some derivative of high-pressure wet jetting.

CleanerBlast is a Better Fit for Shipyard Operations:

  • Low environmental impact.

  • Low pressure mitigates risk of worker injuries and respiratory hazards.

  • Eliminates many fire and ignition hazards common to dry blast methods (dust, friction, heat).

  • Vapor encapsulated grit drops to workplace floor to contain waste dispersal to work area.

  • 92% less dust creation won’t trigger sensors .

  • Suitable for use in enclosed spaces and close proximity (15 feet) of welding operations.

  • Cleans without risk of pitting or damage to delicate gel coat over fiberglass.

  • No wet sanding or tenting needed.

  • Creates perfect 80 grit finish ideal for paint adhesion on metal (Interlux).

  • · Cool vapor process prevents heat warping and changing close tolerance critical dimensions.

  • Works with a wide range of media sizes (fine to coarse) and types, including soft organic media, soda, minerals, zero-silica grit and crushed glass/beads.

  • Supercharged efficiency for fine grit: Greatly exceeds dry blast productivity and surface cleaning power.

  • Low consumption: 90% less grit than dry blast, 1/3 the water of hydrojetting, 13% less energy than high pressure methods.

  • Fast, easy setup, highly mobile and compact systems fit in tight areas mobility.

  • Extremely low waste generation: high efficiency means less mess, less containment.

CleanerBlast Is a Tool Shipyards Use To:

  • Expose welds quickly for inspection and maintenance.

  • Easily remove barnacles, marine growth, biofilm and coatings.

  • Work across multiple surface types: fiberglass, aluminum, wood, steel, brass, rubber, plastic, stainless steel, glass.

  • Peen aluminum to retexture (smooth) and strengthen by eliminating porosity to seal surface against staining and oxidation.

  • Remove microlayers of oxidized metal and corrosion, restore oxidized paint.

  • Clean running gear and ballast tanks with years of barnacle and marine growth buildup in minutes.

  • Restore props, rudders and trim tab without the need for removal from vessel.

  • Clean entire diameter of pipes, including inclines and U-bends.

  • Remove coatings precisely – layer by layer or multiple layers at a time.

CleanerBlast is Engineered to Enhance the Entire Process:

  • Equal or better performance and results compared to dry methods.

  • Easy to use ‘set and forget’ adjustments uses hydraulic pressure to keep consistent pressure and flow. (No air pressure drops)

  • Switch to rinse in seconds using from the integrated deadman control.

  • No clogging; totally unaffected by high humidity.

  • Durable stainless steel construction, lowest mechanical breakdown in industry.

  • Standard, easy to procure replacement components and easy access for fast, “drop-in” maintenance.

  • Standing water supply tank eliminates need for hose hookup.

  • Automatically pressurizing hopper, dedicated fill pump and quick load tray cut setup and reload time up to 90%.

  • Engineered for exponentially less wear on critical parts like hoses and valves

  • Chemical treatments in the water tank allow simultaneous metal cleaning, salt removal and mitigation of rust back.

  • Supports total process approach 100% compatible with new technologies including water conditioners, zero-silicate grits, non-toxic, biodegradable salt removal/tea-stain (flash rust) prevention treatments, and blast bag waste containment.
