Barkly Square Cathodic Protection Project

Location

Brunswick, Victoria

Client

ADCO Constructions PTY LTD

Contract type

Lump Sum - $600,000

Project dates

Feb 2013 – Aug 2013

 

The Barkly Square shopping centre is a department centre serving the inner northern region of Melbourne. The centre is located on Sydney Road within the suburb of Brunswick, approximately 4 km from the Melbourne CBD. As part of the revitalisation, the in-ground substructure of the building needed a new Cathodic Protection system.

Australasian Corrosion Consultants were tasked with replacing the original Cathodic Protection system installed in 1985. The anodes from the original system were consumed and replaced using 4 horizontal anodes installed between the foundation piling. The two existing Cathodic Protection Rectifier Units (CPRU’s) were removed and both were replaced with a new higher capacity system at the eastern side of the building.

The works involved the horizontal drilling underneath the structure of the building from the eastern car park and the installation of steel sleeving to house the anode systems. The steel sleeves were driven into place using a horizontal pneumatic hammer at lengths of 6.5m, these were welded together at each end to make a continuous sleeve. The anodes were then installed in the sleeve using the horizontal drill rig and a “Steel Bullet” mechanism designed by ACC.

The drilling works were undertaken by R&R McClures Excavations Pty Ltd with support and supervision by ACC.

Norke Skog Boyer Paper Mill Cathodic Protection

Location

New Norfolk, Tasmania

Client

Norske Skog

Contract type

Lump Sum - $105,000

Project dates

Feb 2013 – May 2013

 

Australasian Corrosion Consultants were commissioned by Norke Skog Tasmania to perform a failure investigation on section 1 of the Boyer Paper Mill Water Main. The failure of the main occurred in December 2008, which led to a plant shut down for a period of 24 hours. The investigation found that the pipeline was buried in a corrosive environment and the coating contained numerous defects along its length. A detailed design was completed for an impressed current cathodic protection system in 2012 and ACC were awarded the work to install and commission the system. The design was intended to stop or minimise further corrosion of the water main between Boyer Paper Mill and Pulpit Rd as well as provide a suitable mitigation system.

As part of the project a training course on corrosion was provided to Boyer staff. ACC tailored the training course to provide staff with a fundamental basis on the mechanisms of corrosion and the systems that can be used to ensure long term asset durability.

BP - Aircraft Fuelling Installations: Aviation Monitoring

Location

Various Locations, Vic & NSW

Client

BP - Australia

Contract type

Annual - Rate

Project dates

Yearly - March

 

As part of Australasian Corrosion Consultants’ monitoring works for BP Australia an annual cathodic protection monitoring survey is performed on buried steel fuel tanks containing aviation fuels at multiple airports in Victoria. In order to safely and efficiently cover the large distances and minimise costs required to travel between each fuelling station, ACC performs the survey using a chartered aircraft. Use of the aircraft allows the work to be completed by a single man and the pilot, removing the need for long distance driving..

By using this methodology, ACC are able to complete a monitoring survey across 17 different sites in Victoria and NSW in half the time required via motor vehicle.

BP - Pipeline Program

Locations

BP Terminal - Burnie Tas

BP Terminal - Gladstone QLD

BP Terminal - Mackay QLD

Client

BP - Australia

Contract type

Lump Sum - $65,000

Project dates

April 2013 – June 2013

 

Australasian Corrosion Consultants were commissioned by BP - Australia to perform a Direct Current Voltage Gradient (DCVG) survey and a Close Interval Potential Survey (CIPS), over the length of the BP-Burnie, BP-Gladstone and BP-Mackay Wharflines, as part of the BP Australia’s pipeline baseline programme. The programme was seeking to complete baseline wall thickness testing of BP owned and operated Terminal pipelines as part of a national Pipeline Integrity Management System (PIMS). After the DCVG and CIPS surveys were performed, ACC located the coating defects present over the Wharflines where Ultrasonic Thickness Test (UTT) would be most beneficial. Furthermore, ACC could determine the steady state level of protection being applied to the Wharflines by the existing cathodic protection systems.

Performing this survey allows ACC to make recommendations to provide the client with ability to improve the durability of their assets.

Majestic Building Façade Remediation

Location

St Kilda, Victoria

Client

Remedial Engineering

Contract type

Lump Sum - $400,000

Project dates

July 2011 – September 2011

 

Australasian Corrosion Consultants were tasked with design and installation of a cathodic protection system as part of the remediation of the iconic Majestic Building on Fitzroy Street in St Kilda. The façade of the building is constructed of steel structural members encased in mortar and brickwork. Investigations found that corrosion of the steel columns had resulted in cracking of the façade brickwork and significant damage to the façade of the building. ACC supervised the installation of a Duogard hybrid cathodic protection system.

Duogard anodes are a discreet sacrificial anode that utilises an impressed current phase to complete the initial polarisation. Grout was pumped around the steel columns to provide a uniform medium in which to install the anodes. These anodes were installed in the façade of the building through the use of abseilers under the supervision of ACC.

NMIT Stray Traction Corrosion Investigation

Location

Epping, Victoria

Client

Melbourne Polytechnic

Contract type

Rate

Project dates

December 2013 – May 2015

 

 

ACC were commisioned by North Melbourne Institute of Technology to determine the cause of accelereated failure of the copper water pipe network located at their Epping campus. ACC, in conjunction with Energy Safe Victoria, determined that the adjacent rail network was cauing a shift in pipework potential, resuling in Stray Traction Corrosion.

 

After significant testing and continuity bonding works were performed, a suitable drainage system was designed in conjunction with all other asset owners in the vicinity.

 

Protecting assets from stray traction corrosion requires a signficant amount of cooperation between asset owners and Energy Safe Victoria.
