A shutdown of this scale is normally a lengthy and cost intensive process, however, with an alternative approach CQFMS were able to save the client both time and money.
Working with their in-house engineering team and collaborating with BHP Operations Services, CQFMS developed a shutdown plan unlike any other. The plan enabled both the engine/hydraulic modules and slew bearing replacement – along with the large component scope – to be completed at the same time.
This alternate approach saved 14 shifts of work compared to the conventional shutdown method which usually involves completing each stage of the shutdown separately.
CQFMS Diesel Division Manager Reahan McBain said the splitting of the machine allowed for multiple work fronts to be carried out, reducing interaction.
“All outstanding defect work and components were completed in a reduced duration due to the machine jacking and outage being combined,” Mr McBain said. “The machine returned to work and has been running at 98% availability.”
FMS Group Engineering and Product Manager Triston Gibson completed multiple lift calculations to ensure the jacking process was safe, using a stability model to test each lift. This process was vital to achieving a successful outcome and providing peace of mind to both the client and the team on the ground.
BHP Maintenance Superintendent Phil Starr said the innovative shutdown approach was a first for the BHP fleet – both in Australia and internationally – and would be highly considered for future projects.
“This is an exceptional example of adopting a collaborative approach and innovative thinking to develop solutions not only to minimise downtime, but also exceed safety, quality and performance outcomes,” he said. “This shutdown method dramatically reduced the risk of traditional safety interactions and provided a far safer work environment. We also had a huge uplift in scope duration and machine performance.”
Field Mining Services Group are equipped to carry out all aspects of large-scale shutdowns – including jacking, engineering and labour – and are excited to continue implementing new methods to achieve quality results for their clients.
