in Benoni, where they underwent a com- plete strip-down assessment. New radiator cores and piping were manufactured for the cooling system. A new engine pre-heat system was designed, manufactured and installed and minor engine repairs were performed. The original analogue control systems in the control rooms were replaced by state-of-the-art automated digital systems, along with compatible engine governors. “We subcontracted this work to automa- tion specialists. The upgrade involved complete redesigning of the control pan- els and wiring. It represents a big advance over the old system in terms of speed, efficiency and automatic monitoring of the condition of the entire generator set equipment,”Myall says. “A major advantage for this and other customers is that Marthinusen & Coutts is able to assume complete responsibil- ity for all the electrical and mechanical equipment involved and offer a turnkey solution,”Myall concludes.

Clive Myall, Marthinusen & Coutts’ Field Service Manager, says this lead- ing electrical rotating machinery service provider was awarded the contract to refurbish two mobile gen- erator sets. The two generator sets provide backup power at the mine outside Rustenburg. The project involved servicing the 2 200 kVA alternators and MTU engines as well as managing the servicing and refurbishment of all associated equipment. Myall says that some of the electrical equipment had to be replaced and upgraded with the help of specialist suppliers and service providers. Both mobile units, originally manufactured in 1986, were taken to Marthinusen & Coutts’ Power Generation equipment repair facility
