Oil and Gas Decommissioning works in Australian waters.
Transforming Oil & Gas Decommissioning with Innovative Technologies
The Australian Oil and Gas industry has commenced the decommissioning of USD $40 billion of Oil and Gas assets in Australian waters over the next 15 years.
NOPSEMA is overseeing those operations.
The Centre of Decommissioning Australia or CODA is an independent body that is bringing together the key stakeholders in government and industry to enable the development of a world-class decommissioning sector.
A wide range of Australian and overseas companies are pushing the boundaries of innovation to protect the ocean whilst recycling 95% of all equipment recovered.
ARI Water Solutions, a CODA partner, offers filtration technology that protects the environment from the physical waste created during decommissioning works both on land and subsea.
A Vision for Decommissioning with ARI
ARI Technology means we can now:
- Protect runoff from land based decommissioning works with 'at source' stormwater filtration.
- Recover 'flexible flowlines' with NORMS (naturally occurring radioactive material) radioactive scale captured at one end of the pipe as recovery occurs.
- 'Subsea flexible flowlines and rigid pipelines typically need to be cut prior to recovery, exposing the environment to residual contaminants within the pipelines. Contaminated debris can dislodge during the recovery process and migrate towards the end of the pipeline and into the environment.
- We are also developing 'false floor filtration' to be fitted to containers during recovery from sea bed works.
- 'Significant science and engineering has been carried out by Blakemere to provide a solution that ensures subsea waste is contained during pipeline recovery operations.
ARI, utilizing world first ‘high flow to fine particle capture filtration’ technology to ensure global Oil and Gas Decommissioning works have a minimal impact on the ocean.

The Technology.
ARI HFPF Material (High Flow Poly Filter) has been proven to process over 3000 litres per minute (3080), per square metre capturing particulates down to 63µm (micron).
Land based works expose the water environments to runoff where decommissioning works are carried out both on covered and uncovered surfaces. With climate change effects, rain events are larger, faster in a shorter period of time. This carries significantly more waste into the drains during rainfall.
Stormwater drains around the works sites should be fitted with ARI ‘s Stormwater Filtration Device (SFD) or ‘at source’ treatment. ARI or contracted waste management companies will carry out the ongoing servicing and waste management.
ARI Technology has been used as a dust suppression fence. This may be of use in situations where toxic waste can be transported by the wind.
Subsea flexible and rigid flowline to be recovered may need to be disconnected or cut on the sea floor .
ARI's high flow to fine particle filtration is ideal for recovering equipment from the sea bed. This equipment can now be lifted to the surface level and above without losing the waste that has accumulated in these pipes whilst allowing the seawater to drain.
Significant science and engineering has been carried out by Blakemere and ARI to provide a solution that ensures subsea waste is contained during pipeline recovery operations.
ARI’s High Flow to Fine Particle Capture technology (HFFPF) filtration technology is aimed at protecting the ocean during recovery operations which includes radioactive scale. A Thesis carried out at Edith Cowan University, a component of a world first PhD on the base load of radiation present in the minerals we mine has proven ARI’s filtration technology in this space.
Our Commitment
In Australia, the Oil and Gas Industry is setting new global standards for environmental protection during decommissioning.
ARI is committed to developing filtering solutions to suit decommissioning industry requirements.
Until now, decommissioning operations in this and multiple industries around the world were not responsible for the water contamination they created.
Globally in 2024, the Oil and Gas industry has ensured the environment is the top priority during decommissioning works.
ARI make the SFD to suit any drain.
The SFD meets all hydraulic rules and is "fit for purpose".
Decommissioning Works
Wash Bay protection.
The waste washed from equipment enters the drain, blocking the pickup pump, the oily water separator, the chlorinator, then the filter bank, making maintenance a significant cost that is now minimised.
The ARI WBD filters all water and waste to 63µm prior to pit floor and system contamination.
Sludge Dewatering.
Here, we are pumping flocculated, iron rich dewatering sludge into an IBC lined with ARI HFPF Technology.
The purpose of this video is to demonstrate how we can separate the water from the sludge. Note: There is only one outlet on an IBC which does not demonstrate the flow rate capacity of the technology. To overcome this, we have developed the ARI Mega Basket 1 cubic meter. See below.
ARI Pillows polish the "shock" hydrocarbon and heavy metals loads that enter the drain during filtration.
If PFAS is present in the water, it will also be captured.*
*Has been proven to work in road runoff, vehicle wash bays, not for use as a grease trap.
The Mega Basket captures physical matter and sediment in high flow/volume applications.
One Mega Basket filters 16,000 litres per minute down to 63µm.
ARI Mega Basket Mining Spec Coming Soon.
ARI "continuous processing" Coming Soon.
