Relocatable Switchroom Design Tackles Major Water Issues

Underground water has been a major issue for Centennial Coal’s Springvale mining site, which is why the mining company contracted Ampcontrol to design, manufacture, assemble and test a relocatable switchroom along with commissioning the high voltage switchgear and Toshiba VVVF Drive System.

Ampcontrol’s Grant Waring, Senior Electrical Engineer, explained, “The Centennial Coal site has traditionally experienced major, widespread underground water issues. The Ampcontrol switchroom therefore needed to be relocatable, allowing for power supply to support the pumping of water in a range of locations.”

The switchroom is designed to run a 4kV variable frequency 700kW submersible borehole pump at a depth of 390m with an output flow rate of 100 litres per second.

As experts in hazardous area design, Ampcontrol successfully developed the switchroom with the borehole in mind and incorporated explosion protection, based on Ex p, for the borehole and pumping operations.

“This is the first in a series of switchroom designs for this site,” adds Waring, “and we are looking forward to working with the range of challenges the site will ‘throw at us’ in the future.”

Ampcontrol Delivers Important Power Infrastructure for WestConnex

In late 2017, Ampcontrol was contracted by CPB Contractors to deliver 46 transportable Electrical Equipment Rooms (EERs) to power the WestConnex tunnel project including critical fire control, air quality and fan systems. This week Ampcontrol completed the final room, ready for dispatch to the new M5 tunnel.

Traditionally, the permanent electrical fitout for tunnels in Australia had been constructed in-situ in the tunnel, requiring large trades’ team and significant logistics of moving the required materials.

The approach adopted by Ampcontrol focussed on offsite manufacturing and provided several benefits including:

  • the ability to manufacture in a controlled workshop environment which enabled increased productivity and improved safety;
  • full factory acceptance testing;
  • ability to store EERs offsite to be brought forward at the optimum time for tunnel construction and fitout schedule; and
  • rapid install and commission with significantly less site labour required.

This represented the first time that transportable EERs had been utilised in major tunnel in Australia. The rooms were manufactured in Ampcontrol’s Newcastle operations and installed directly in the tunnel in Sydney.

“As a business, we’re extremely proud of our team’s ability to reach this key milestone for the WestConnex project, working with CPB Contractors. We’ve worked hard to ensure all 46 EERs have been manufactured and delivered on time and to specification against a demanding project schedule,” said Ampcontrol CEO and Managing Director Rod Henderson.

“While this represents an Australian first approach, the success of the transportable EERs on this project and significant benefits they offer means that we expect this to be adopted more widely in Australian projects going forward,” said Mr Henderson.

In addition, Ampcontrol also provided the temporary electrical infrastructure to power the WestConnex tunnel construction phase.

AMPCONTROL DELIVERS ‘PURE’ WATER TO REMOTE COMMUNITY IN THE NT

Solving problems comes as second nature to Ampcontrol, one of Australia’s largest and most successful electrical engineering and manufacturing companies. When presented with the challenge of delivering drinkable water to a remote, indigenous community approximately 75kms from Alice Springs in the Northern Territory, the team set about engineering a solution that could be maintained and supported locally.

Partnering with Aurecon on the design of the hydrology system, Ampcontrol devised a unique and entirely portable solution that literally transforms undrinkable bore water into pure water. The parties dubbed this Project Gilghi, with Gilghi meaning “water” or “place of water” in the Barkindji indigenous language.

“Innovation is very much a part of the culture at Ampcontrol, and we specialise in electrical design and advanced manufacturing. We are grateful for this opportunity provided by the Northern Territory Department of Local Government, Housing and Community Development and Ingkerreke Outstations Resource Services. Our partnership with Aurecon meant we were able to leverage the respective strengths of our two organisations and deliver a truly unique solution” said Ampcontrol’s CEO and Managing Director, Rod Henderson.

After months of collaborative engineering between Ampcontrol and Aurecon specialists to devise the reverse osmosis water treatment plant and electrical infrastructure to power the system, what looks like a shipping container with solar panels has meant the people of Gillen Bore have immediate access to clean, contaminant free drinking water. The bore was sunk in 2014, however the community were still getting their drinking water trucked in until the system was installed onsite in late February.

Aurecon’s Design Director for Water and Wastewater Treatment Julian Briggs said groundwaters in arid areas commonly consist of high concentrations of salts as well as minerals, often described as ‘hard water’, which can cause problems both for human consumption and for household technologies designed for softer waters.

“By partnering with Ampcontrol what we have been able to achieve is something that is fit for purpose and scalable to the environment. We’ve designed a transformative technology that will have an immediate impact on the local community,” Mr Briggs said.

The local community created a beautiful artwork titled “honey ant dreaming”, which is a big part of their culture – this was installed on the exterior of the system and provides a great visual connection for the people and their new water source.

With the system now up and running, both Aurecon and Ampcontrol are looking at further applications in remote areas and indigenous communities across Australia.

Supporting power and communication requirements for WestConnex

Ampcontrol was contracted to supply 45 electrical equipment rooms (EERs) for WestConnex, Australia’s largest transport infrastructure project. The EERs include a transformer, switches, circuits and communication systems to assist with fire control, air quality and fan systems.

Westconnex is the first tunnelling project in Australia where EERs have been manufactured offsite and installed directly into the tunnel, compared to the traditional method of building them in-situ. This method has resulted in a number of positive benefits for the project, namely significantly reduced install time, improved safety and a decrease in the resources required for installation.

Mechanical Analysis of a 25MW Turbine

Ampcontrol was engaged to analyse machine vibration on a 25MW turbine at an alternative power generation facility in QLD.

Achievements

  • Machine balancing
  • Identification and rectification of an oil whip issue
  • Quick implementation of a solution, minimising downtime

The Project

A 25MW turbine at the facility was experiencing high levels of vibration after being returned to service from overhaul.

Ampcontrol’s mechanical team attended the site and balanced the turbine. After balancing, the turbine ran with a very low level of vibration, significantly less that before overhaul.

The vibration level of the turbine remained low until reaching half load, when the vibration spiked unexpectedly and the machine tripped.

Ampcontrol reviewed the overhaul work and data from the vibration spike and trip. The fault was identified as an oil whip caused by the bearing being unloaded by the partial arc steam admission to the turbine. Exacerbating factors included the bearing journals being machined during the overhaul to the minimum diameter allowable and a combination of the as left alignment of the machine and the very good balance condition.

Oil whip as a result of increasing machine load such as this is uncommon. Commonly oil whip is a condition seen during transient machine operation, as an oil whirl latches onto a shafts natural frequency.

Our analysis indicated that this oil whip was being caused by the bearing being unloaded due to partial arc steam admission. This is where, at lower loads, steam is supplied through multiple valves opened sequentially to minimise throttle losses.

The machine design consisted of two main steam valves opening one after the other providing steam to just under 50% of the inlet.

Analysis of the machine dynamic characteristics indicated that if the sequencing of the inlet valves was reversed the unloading that peaked at 50% load would be reversed and bearing stability would be increased.

Ampcontrol proposed a machine configuration change that would rectify the problem and the OEM of the machine carried out this modification with minimal downtime.

Once the solution was implemented the turbine ran to full load for the rest of the season without any further vibration issues.
