Vero Laser is your commercial advantage for coatings and surface preparation compared to outdated alternative methods. 

The current system is expensive, operationally dangerous and often quality control is low.

Laser cleaning technology is cost-effective, allows staff to carry out work safely and is compliant with Australian environmental laws. 

Below we display some case studies for various laser cleaning applications.

 

Laser cleaning lead-based coating removal project

Current practice summary

Historically, critical infrastructure in Australia and New Zealand made from steel was often coated with lead-based paint.

In the current day much of this infrastructure is reaching beyond its design life and requiring maintenance.

To execute maintenance engineers have previously been limited in their options to either chemical stripping or abrasive blasting for the removal of lead-based coating.

Problems

Environmental laws require full containment to capture spent abrasive and chemical agents now contaminated with toxic paint particles from entering sensitive habitats.

This material must be disposed of in suitable landfills.

The current system is costly, operationally dangerous and often quality control is low.

Laser cleaning advantage

Vero Laser provides laser cleaning to remove lead-based coatings from structures enabling engineers and their technicians to carry out maintenance work in a safe environment.

When weighing up the associated project costs, Vero Laser delivers a commercial advantage to outdated alternative methods.

High intensity amplified lighting structure

Current practice summary

Our client faced some unique challenges to deliver the High Intensity Amplified Lighting (HIAL) structure at Australia’s newest Brisbane airport. The 390-metre-long steel structure extends into Queensland’s Morton Bay and serves to guide approaching aircraft onto a new 3.3-kilometre runway. After six years of construction this major project is set to open in June 2020.

Problems

Contamination deposited on the horizontal surfaces supporting the walkway and platform decking had compromised the integrity of the coating, subjecting the steel structure to the onset of corrosion in a coastal marine environment. 

The HIAL structure is located adjacent to the Boondall Wetlands nature reserve increasing the client’s concerns when considering contaminate removal by traditional blast cleaning methods using abrasive or water jetting. Further complicating matters is the significant cost associated with the removal of the installed lighting towers to access the decking support structure.

Laser cleaning advantage

Vero Laser’s NACE certified personnel inspected the HIAL steel structure. Samples were removed and tested by QUT’s Science and Engineering Faculty to determine the type of contamination using optical and electron microscopy. 

 

Optical and electron microscopy

 

Scanning electron microscopy and EDS analysis were conducted with JEOL 6360A. Optical images were obtained with a stereo microscope. 

 

Stereo microscope

 

Vero Laser conducted an onsite trial to determine the effectiveness of the laser contaminate removal process. This provided sufficient confidence for our client to proceed to contract works. Our highly mobile 100W unit was deployed to remove the contaminate while the platform decking remained secure. 

 

Laser operation

 

Surface contamination

 

By utilising laser, Vero Laser rapidly removed the surface contamination and retained the existing prime coat.

Laser productivity rates are comparable to traditional industrial cleaning methods using our larger high-powered systems however, the mobility of the 100W unit was ideal for this application. The gains in time with minimal set up and movement far outweighed any other loss.

The 100W laser unit runs off a small 3-KVA generator and has a 3-metre fibre optic cable. For larger high-powered units Vero Laser can provide up to 50 metres of fibre optic cable.

Vero Laser creates minimal noise, no dust and significantly increases operator safety when compared to traditional surface cleaning methods.

“This project is a perfect example how new laser cleaning technology can be implemented to deliver safer, smarter and easier solutions to challenging marine projects.” Ben Gunness, CEO Vero Laser

Vero Laser delivered outstanding results for our client, saving both time and money utilising laser’s ability to remove surface contaminates, retain prime coats and operate with sustainable environmental practices in a nature reserve.
