Shown is our current selection of dredge options. For maximum performance we recommend
matching a dredge to suit your host hydraulic supply. We can however tailor a dredge to specifically
suit your hydraulic supply if by chance your requirements are not covered by our extensive range.

Our patent pending design offers a highly efficient, small and
powerful alternative to current dredging technology.
Quick mobilization and minimum re-configuration time have
been priorities for our clients so we have included in our kit the
vast majority of components needed to field install our dredge
on almost any suitably sized ROV.
Our standard 4-inch dredge has low operating power
requirements of 38 lpm (10 gpm) at 206 bar (3000 psi) which
enable this dredge to be used on most work class and smaller
ROVs currently on the market.
VORTEX has the highest proven suction values in the industry.
With 64kpa of vacuum as our standard 4-inch dredge setting,
the VORTEX ROV and diver dredge has the power to quickly
and efficiently remove material. However, 97kpa of vacuum is
availiable with the Tornado.
01
Global awareness towards energy efficiency has been met by
VORTEX with less energy input than our competitors. We have
achieved this through careful selection of the best components
available, combined with continuous development of new designs.
The use of more efficient designs has resulted in the most
powerful inlet vacuum specifications on the market. Every
customer has the opportunity to maximize their production by
choosing a dredge to best match their host hydraulic supply.
As clients are now finding out, if you have a specific host hydraulic
supply to meet, VORTEX is also happy to modify a dredge unit to
suit your needs.
VORTEX has experience working in the traditional oil and gas
disciplines and the rapidly growing renewable sector such as wind
farms, with our equipment often able to remain on board the ROV
full time due to the modular installation option VORTEX provides.
This dramatically reduces down time re-configuring tooling.

4-inch Dredge
‘STANDARD’
4-inch Dredge
‘TORNADO’
The most powerful 4-inch ROV and diver dredge in the world,
the VORTEX has removal rate performance more commonly seen
in 6 inch dredges.
We have included the option of a jetting head kit, after
extensive development to ensure there is no reduction in water
flow to the dredge unit which can reduce available working
vacuum.
The most powerful 4-inch ROV and diver dredge in the world
has just become even more powerful. The standard VORTEX
4-inch at 64kpa vacuum has removal rate performance more
commonly seen in 6-inch dredges. The VORTEX ‘Tornado’ 4-inch
dredge is capable of a near perfect vacuum - which to our
knowledge, is unheard of with dredge equipment. We have yet
to perform removal rate tests, though the increase in vacuum
would bring according increases in removal rate performance.
Our client’s have been considered with the most complete
dredge system available on the market today.

6-inch Dredge
The Vortex 6-inch is designed for Subsea excavation and disposal
of sediments and gravel up to 140 millimetres. It is easily mounted
to the ROV and requires no ship deck space and sea fastening. The
Vortex 6-inch requires no specialist operator or additional cables
between ship and sea floor.
Has optional jetter kit for breaking up seabed. Our low hydraulic
consumption leaves enough hydraulic supply on most ROV’s to
utilize a purpose built high pressure jetter unit if the task requires
one.
Applications:

Sub sea oil
Absorption Tool
Introduction and assembly:
Please find included one Marine Guardian 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 Marine Guardian 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
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.

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

This tool is designed to remove samples of marine growth
from it’s habitat, suck the samples from the removal area
and contain the samples in one of seven numbered sample
bags for the purpose of recovery to deck and further scientific

This tool is used in conjuction with a Vortex dredge pump
and 2.5 inch Venturi to create the vacuum needed to suck the
samples to the bags.
Sample ‘bags’ are built with cam lock fittings to minimize on
