Gas Hydrate Removal Brush

Maximize diver bottom time.

To be used in conjunction with Vortex reverse flow dredge or with Vortex water pump only as the motive water source.

Water jets on four sides and front of Hydrate cleaning brush utilizing high volume water (62 m3/hr with Tornado pump) and up to 80 psi water pressure (with Tornado pump) generate severe turbulence to break up and disperse the hydrate build up with water pressure and flow.

Mechanical action of bi-directional rotary bush serves to further break up hydrates.

Soft bristles avoid damage to sensitive EFL and HFL assets.

Installation

Parallel brush specifically for class 1 to 4 torque buckets.
Ball type brush for general cleaning
Custom brushes are available upon request.
End caps have 20mm and 38mm holes to fit class 1 to 4 socket shafts.
Two brushes are included in the kit.

Dredging in action

We offer a wide range of dredging solutions to suit most deep sea applications. The below graph shows our current selection of dredge solutions from the Electric 2 1/2 inch, to the larger BLACK HOLE 8 inch dredge.

We can also tailor a dredge solution to specifically suit your hydraulic supply if by chance your requirements are not covered by our extensive range. If you require a custom dredging solution please contact us directly.

Tornado 4" Dredge MkII

With a proven suction inlet vacuum up to 29.5in/hg (100kpa), the patented Vortex 4" T-100 Tornado Dredge is designed for subsea excavation and disposal of seabed materials up to 99mm in size.

Vortex 4" Dredge Pump

The most powerful 4" ROV and diver dredge in the world at 97kpa (28in/hg) vacuum has removal rate performance more commonly seen in 6-inch dredges.

Hurricane 6" Dredge

With a suction inlet vacuum up to 15.3in/hg (52kpa), the patented Vortex 6" Hurricane Dredge is designed for subsea excavation and disposal of seabed materials up to 149mm in size.

Why is Vortex Dredge Superior to other ROV Units?

Vortex dredges have been designed to combine high suction values and high water volumes to tear up sticky soils with very high suction then keep it flowing with high water volume. Powerful, simple, effective.

Example: Getting a "RIDICULOUSLY THICK MILKSHAKE" ® ™ to move through a straw is similar to dredging a very sticky seabed and suction is key because if you drive a suction hose deep into sticky mud the water flow in the suction hose will often stall and the hose is essentially filled with a 'plug' of mud and only high suction will clear the hose. Once the hose is clear then water flow takes over. Suction does the work and water flow continues the work done.

VORTEX performance figures DO NOT have a small print clause with an Asterix symbol next to figures which would represent "best case Scenario" removal rates as opposed to actual removal rates.

VORTEX removal rates are ACTUAL removal rates as seen with actual material moved using Magnetite black iron sand and rocks weighing 2.375kg per liter as to the sample product.
