ARMS Reliability has begun work on a greenfield maintenance strategy development project for the Gruyere Gold Project, a 50:50 Joint Venture between Gold Fields Limited and Gold Road Resources Limited, located within the Yamarna greenstone belt around 200km east of Laverton in WA.

The Gruyere Joint Venture (Gruyere JV) has defined a significant gold deposit of 148 million tonnes grading 1.3 grams per tonne for 6.1 million ounces of contained gold, making it one of the largest undeveloped gold deposits in Australia.

In an effort to leverage the value of conducting maintenance studies on greenfield sites, the Gruyere JV has brought ARMS Reliability in prior to the commissioning of the gold mine to set the scene for success in its asset management department.

ARMS Reliability will execute a Reliability, Availability, Maintainability (RAM) analysis on the design of the plant; and will also develop RCM based maintenance strategies and spare parts cataloging.

"We selected ARMS Reliability because of their proven track record in RAM modelling, and their experience in working on greenfield sites like the Gruyere Gold Project. Undergoing a RAMS study will ensure that this project delivers the most value to our stakeholders," said Brett Foster, Manager - Processing, Gruyere JV.

"By getting in early and conducting these maintenance studies now, we will save money and resources down the track by ensuring optimum performance of the plant from the outset. When we hit the 'go live' button, all maintenance costs and schedules will be well defined- We don't want any surprises," Mr. Foster said.

Gruyere Gold Project has commenced detail engineering, design and construction on site. The ARMS Reliability maintenance project will confirm the design of the plant from a capacity and availability perspective, to ensure it meets throughput targets.

Other benefits of conducting a comprehensive maintenance study on a greenfield site include:

  • Plenty of time to make adjustments to the plant to meet availability targets before construction is complete
  • Detailed maintenance strategies are uploaded into the CMMS and ready for execution before the commissioning phase of the project, and can then be tested during the commission phase and fine-tuned as required
  • Spare parts to support the maintenance strategy are loaded to the CMMS and attached to relevant maintenance strategies to support efficient planning of maintenance
  • Detailed maintenance budget including labour hours can be reviewed and profiled before plant is in operation

As a plant moves closer to commissioning and operations, the ability to influence its RAM capability diminishes greatly.

"ARMS Reliability is delighted to be working on a project with such significance as the Gruyere Gold Project, particularly from such an early stage. We look forward to delivering a maintenance strategy that greatly reduces the probability of failure, increases uptime, and reduces maintenance costs for the life of the mine," said Craig Brydges, Business Development Manager, ARMS Reliability.

The ARMS Reliability project will be finished by September 2018.
