The Norwich Park Mine Field Maintenance Team, along with BHP Billiton Mitsubishi Alliance’s (BMA) Field Maintenance Alliance Partner, Transfield Services, recently completed a 60-day major Dragline shutdown with no recordable injuries — a first for BMA.
Norwich Park General Manager, Ross Willis, said this was the first time he was aware of a shutdown of this magnitude running without a recordable injury.
“The shutdown was also a success in terms of duration and cost; a great deal of effort and planning went into this shutdown and the results speak for themselves,” Ross said.
“It’s a great result which everyone at Norwich Park is very proud of and it demonstrates that BMA’s goal of zero harm is achievable,” he said.
Dragline 34, a Marion 8050, celebrated its thirtieth birthday last year, with a ‘makeover’ including a new paint job and significant upgrades to increase reliability and productivity.
Over the course of the shutdown, 80,000 person hours were worked, by over 220 employees and contractors, with only three minor cases of first aid treatment required.
During the shutdown every component of the dragline was removed, cleaned, inspected and replaced as required.
A number of major works were also carried out, including the installation of a digital control system, while the swing rack, rails and rollers were replaced for the first time since the machine was built.
Norwich Park Maintenance Manager, David Chatto, said this shutdown was a great success and would see Dragline 34 through for another six years with minimal maintenance.
“The success of this shutdown can be attributed to the guidance shown by Norwich Park Mine personnel, everyone’s collaboration and the quality of the planning,” David said.
“The shutdown came in on budget and on time but, most importantly, we had no recordable injuries and are well on the road to zero harm,” he said.
“It is a credit to everybody involved.”
