Subsea Oil Absorption Tool

Maximize diver bottom time.

Introduction and Assembly

Please find included one Subsea oil absorption tool system which has been built specifically for the purpose of absorbing hydrocarbon based contaminants from dilution in water. The funnel will need to be placed above the area of contamination so as to draw away contaminated water and pump it through the filter system. There is no known limitation to how much water can pumped through the filter system.

The Subsea oil absorption tool filter system has been seen to absorb 15 litres of EP80 oil at 50% filter saturation. These absorption rates may change depending on type and quantities of contaminants seen. The water pump out put pressure is restricted to prevent over pressurisation of filter units.

Installation

This kit will need assembly with included funnel Item 1, Inlet hose Item 2, Pump Item 3, Outlet hose Item 4 and filter frame Item 5.

You can orient the ROV handle on the funnel in which ever rotation suits your application.
Pump mounting brackets are also supplied Item 9.
You can mount the outlet nozzle Item 7 in which ever orientation suits your situation.
The pressure reducing valve supplied Item 6 is set to restrict hydraulic supply from the ROV to the specifications required.
Item 8 Is the water pump inlet.

Depending upon your installation, the filter frame may be required to mount vertically or horizontally as shown in these options. Orientation will not affect performance. Filter mounting brackets are supplied as shown.

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.
