of industrial plant and equipment,
including four bulk shipments of
over 18,000m
3
(635,500 ft
3
) and
280 shipping containers of plant
and equipmentwas salvaged and
shipped toShandongProvince in
China.Over 2,000bulkunitswere
methodicallydismantled, cleaned
to export standard,matchmarked,
labelled, recorded andpacked, with
each itemgiven clear instructions on
how tobe reassembled inChina.
The salvaged items included
the 65m (214 ft) high, 1,200 tonne
coal drying andgrinding structure,
the flue gas desulphurisationplant,
hotmetal handling equipment, including an
80 tonne induction furnace, thehotmetal
desulphurisationplant, off gas scrubbing and
cooling infrastructure and a 25megawatt
power station. Carryingout lifts of up to108
tonne, thedismantlingprocess reliedheavily
on complex engineering lifts using large
crawler andmobile cranes.
Throughout theproject Liberty Industrial
managedmultiple crews acrossmultiple
workfrontswithin a small footprint.
Theprojectworkforcehit its peak in the
dismantlingphaseof theproject at 60
personnel including significant senior
management and a supervisory teamof two
projectmanagers, three safetymanagers,
five supervisors and three leadinghands,
supportedby a teamof fiveproject engineers.
Once thedismantlingphaseof the
project hadbeen successfully completed,
Liberty Industrial commenceddemolition
of themajor structures, utilising engineered
induced collapsemethods todemolish the
larger structures, including the 75m (246
ft) tall, 1,700 tonnepreheater structure. This
structure, due to risks associatedwith its
proximity to adjoiningoperating industrial
facilities, wasmodelledusing the company’s
proprietaryASI ExtremeLoading software.
Liberty Industrial implemented its
DemolitionRiskAssessmentWorkshop
(DRAW) systemon theproject. TheDRAW
system forms part of its thirdparty certified
AS4801:2001SafetyManagement System and
is the foundation for the company’s approach
tohazard and riskmanagement. The resulting
DRAW then feeds down to thedevelopment
of task specificRiskAssessments and Job
HazardAnalyses.
L
iberty Industrial carriedout the
deconstructionof RioTinto’sHigh
Intensity Smelting facility inKwinana,
WesternAustralia. Theproject involved
thedismantling and relocationof almost
half of theHismelt plant, whichwas sold to
Chinese companyMolong anddismantled
and shipped toChina for reconstruction. This
undertakingwas the first of its kindwith the
project involving the complexdismantling
of significant components of industrial plant
- never beforehas adismantlingproject of
this scale and complexitybeen attempted in
Australia.
Deconstructionworks commenced in
January2013with thedismantlingphase of
theproject. In total,more than7,000 tonnes
