Seabed Sample Grab Tool

Maximize diver bottom time.

Please refer to clients instructions for maximum decent rate through splash zone, decent through water column and landing out subsea.

The new design incorporates 620mm of vertical travel before bucket closing mechanism is activated, dramatically increasing deployment capabilities in rough sea state.

    • Maximum working load = 150kg
    • Sample bucket capacity = 24.7 liter volume total (collective total of four buckets)
    • Overall height = 1296mm
    • Overall width = 1200mm
    • Gross weight = 115kg

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.
