MODERN MINING

The ability of Marthinusen & Coutts, a
division of ACTOM, to manage complex
Mobile gensets refurbished for Impala
turnkey projects has again been under-
pinned by the successful completion of a
project for Impala Platinum Mine.
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
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.
