Orica is the world’s largest provider of commercial explosives and blasting systems, delivering innovative solutions to the open cut and underground mining, quarry, civil construction, tunnelling and oil and gas markets.
Orica engaged Austline Fabrications to fabricate a range of tanks and pipe spooling for their mining services project at Boddington Gold Mine in Western Australia.
In a world first, Austline were given the opportunity to fabricate a capabilities/water treatment module which combined micro-filtration and reverse osmosis carbon filtration systems on the same transportable skid. The resulting module was capable of converting 30,000L of waste capabilities/water into potable capabilities/water every hour.
COLLABORATIVE APPROACH
Veolia originally came to Austline Fabrications with the concept. Using Austline’s experience with building both reverse osmosis and micro-filtration skids, the Project Managers collaborated to develop working drawings and a practical concept based on Austline’s experience and technical feedback.
PRECISION FABRICATION
Austline was chosen as the successful candidate due to their previous experience with complex filtration projects combined with their reputation for a high quality finished product. SAF duplex 2205 steel was used for all high pressure pipework and the entire module fit on a 12 metre skid for ease of assembly.
Austline’s General Manager, Tom Moultrie said “We were excited to be a part of this project since it had never been done before.” The module fabrication was completed within the tight three month schedule and we were delighted with the finished product.”
SCOPE OF WORKS
Fabrication of individual components using a combination of stainless and SAF duplex 2205 steel
Container modifications for skid
Installed equipment pipework
Fabricated cable trays
Installed all air lines and controls
Assisted electrical trades with installation
Access ladders and safety rails
Assisted with commissioning
Disassembled and packaged for safe and secure delivery to site
In 2012, Austline was engaged by Iluka Mineral Sands to assist with the refurbishment of their conveyor transfer system at the North Capel mineral separation plant in Western Australia.
The conveyor is designed to transfer 1000 tones of mineral sands per day through a synthetic rutile kiln at temperatures reaching 800 degrees Celsius. The high temperature causes systematic wear of the conveyor which required refurbishment by the Austline Fabrication team.
SCOPE OF WORKS
More than 100 metres of conveyor was dismantled and transported to Austline Fabrications Welshpool workshop for refurbishment, then transported back to site and integrated with new conveyor systems which included;
Pod outlet chute assemblies including cut-off gates and vacuum connections
Pod discharge chain conveyor including fabrication of casings, head and tail in mild steel, chain and drive assemblies and supports
Connecting chute and blocked chute detector
Conveyor extensions including casing fabrication and chain assemblies
Outlet chute assemblies including cut off gates and compensators
Screening chain conveyor
Emergency dump chute
Charge hopper
Hopper discharge chain conveyor and outlet chute with compensator
Elevator discharge chute with outlet and buffer hopper
Bucket elevator including fabrication of casings, chain assembly, bucket supply, drive assembly and blocked chute detectors
Austline Fabrications was awarded the contract by Veolia Water to fabricate a two-pass Brackish Water Reverse Osmosis (BWRO) Plant for the new North Rankin B platform, installed 100 metres from the existing North Rankin A platform. The BWRO was designed by Veolia to produce demin capabilities/water with very low chloride levels for topping up of the platform tempered capabilities/water system.
RETURNING CUSTOMERS
This project was Austline’s third capabilities/water treatment skid built for Veolia, who knew they could rely on Austline’s experience and professionalism to deliver the best quality product on time.
The BWRO plant treats potable capabilities/water from the North Rankin A Sea Water Reverse Osmosis unit, which was also fabricated by the Austline Fabrications team in 2010. After successfully completing the Sea Water Reverse Osmosis unit, Austline were able to find efficiencies for the new model which was delivered in 2011. This model was designed to treat 120 cubic metres of capabilities/water every day.
In 2010, Kaefer awarded Austline Fabrications a contract to fabricate six portable blast rooms for use in their resources projects throughout Western Australia.
Each blast room was manufactured to include ventilation and air conditioning with the blasting room fully ventilated and insulated from the external environment.
TRANSPORTABLE
The most important aspect of the blast rooms was their ability to be transported from site to site as Kaefer’s project requirements changed. Austline worked with Kaefer’s draft engineers to assist with this process.
Austline’s experience in building transportable skid-mounted equipment allowed the Austline team to suggest modifications to the skid system to allow for a multiple lifting option depending on the site requirements and plant availability.
