Subsea cleaning, cavitation

The system is based on the principles of cavitation, when collapsing bubbles generated by a proprietary system quickly and safely removes fouling materials.
The advantages of this system over conventional high pressure blasting, grit blasters, barnacle blasters or brush cleaning are many:

  • The systems are safe to use. The water stream will not inflict damage to a diver who may come in contact accidentally. 
  • The lance grip nozzle system is compact, enabling cleaning of geometrically complex surfaces. 
  • All types of marine growth, from seaweed to hard well-attached barnacles, are easily removed, with only one pass, saving operators time and money. 
  • Surfaces with paint, varnish or anti-fouling coatings are not disturbed when cleaned, and heavy metals or other contaminants are not released into the water. 
  • The systems use either fresh water or seawater. 
  • The cavitation system leaves a smooth surface that retards biological growth and decreases cleaning frequency. 
  • The systems range from small, compact and lightweight, to larger units that fit comfortable in the bed of a pickup truck or workboat.
  • Equipment available for rental

The CaviDome is developed to be able to clean larger areas in one sweep. See datasheet on the right.
