Outage Surveys — Perth

TL;DR: ISS delivers outage surveys across Perth, the Kwinana Industrial Area and statewide on a FIFO basis — the precision alignment, fit-check and as-built measurement carried out inside the fixed window when a refinery, power station or process line is taken offline. For WA operators losing $50,000–200,000 per hour of downtime, a well-planned shutdown survey in Perth stays off the critical path and protects the restart. We stage and calibrate from Perth, mobilise to your shutdown calendar, and report critical results on the spot so the window never waits on measurement.

Key takeaways

• An outage survey is a shutdown survey scoped to a specific, time-bound window — an alumina refinery turnaround, a Collie power-unit outage, a Pilbara mill reline — where the asset earns nothing until it restarts, so measurement is engineered to fit the schedule, not the reverse.
• The Kwinana Industrial Area concentrates more turnaround duty than anywhere else in WA: Alcoa and South32 alumina calciners and digesters, BHP's Kwinana nickel refinery autoclaves, Cockburn Cement kilns and Albemarle's Kemerton lithium trains, with Collie's coal units and FIFO mill relines adding the rest.
• ISS achieves ±0.3–1.0 mm rotating-equipment alignment, ±0.02–0.05 mm coaxiality with a FARO laser tracker, and 2–6 mm at 50 m as-built scanning with a Leica RTC360, all calibrated to ISO/IEC 17025.
• The work splits into pre-outage baseline capture, in-outage alignment and fit-check, and post-outage as-built verification — with the control network established before the area is congested with scaffold and cranes.
• ISS is independent of any OEM, holds WA mine-site passports and Kwinana high-risk plant inductions, and mobilises from Perth faster than an interstate or overseas service crew.

Outage surveys for Perth and WA process industry

Perth is the operational headquarters of Australia's resources sector, and the assets that drive demand for a shutdown survey cluster tightly around the city and the heavy-industry precincts south of it. A shutdown survey — an outage survey, in power-generation language — is the dimensional control, alignment and as-built measurement work carried out while an industrial asset is deliberately offline for a defined maintenance window: an alumina refinery turnaround, a power-unit outage, a calciner or autoclave change-out, a mill reline. The defining constraint is not accuracy alone; it is the window. A shutdown survey in Perth means staging that capability close to the Kwinana precinct where most of WA's turnaround duty sits — not flying it in from interstate when the clock is already running.

What makes this work specific to Perth is the operating context. WA's process plant runs hard, on continuous duty feeding export schedules, in hot, salt-laden coastal air on the shores of Cockburn Sound. The survey-dependent activities — rotor and coupling alignment, baseplate flatness on cleaned foundations, fit-check of a replacement calciner module, as-built capture of opened internals — can only happen while the unit is cold and accessible. Miss the window and the next chance is a year away; overrun it and the lost-production bill dwarfs the survey. This page covers where shutdown surveys apply across the region, the method and equipment we bring, the standards we work to, and why an independent surveyor staged in Perth is the right call when your restart depends on verified geometry.

Key point: An outage survey is not a routine alignment job that happens to fall during a shutdown. A method that is "more accurate" but two hours slower can cost more than it saves when an hour of WA refinery downtime runs to six figures.

Where outage surveys apply across the Perth region

WA's turnaround and outage duty is concentrated in the Kwinana Industrial Area — the state's largest industrial precinct, roughly 8,000 hectares on Cockburn Sound — with major additional demand from Collie's coal-fired power units and the FIFO mill, calciner and induration shutdowns ISS reaches from Perth. The headline assets are the alumina refineries: Alcoa's Kwinana operations and South32's Worsley refinery run digesters, calciners and large rotating equipment that are removed, rebuilt or replaced on planned turnaround cycles, with shell alignment and tie-in fit-up all survey-dependent. BHP's Kwinana nickel refinery brings autoclave, electrowinning-cell and materials-handling work into the same shutdown discipline.

These operations share one demand: verified geometry delivered inside a window that does not move. The density of process plant around Kwinana lets ISS establish a control network, baseline an asset and return for the in-outage work without long lead times — and hold that control between shutdowns so each turnaround builds on the last. For remote Pilbara and Goldfields mill relines, the same methodology travels with our FIFO teams, staged and calibrated in Perth before mobilisation.

Watch out: The most common cause of survey-driven outage overrun on a WA turnaround is not measurement error — it is scope discovered too late. Treating the surveyor as a day-of call-out rather than a scheduled, resourced activity almost guarantees lost hours waiting for control, access or line of sight.

Method and equipment we bring to a Perth outage

Outage instrumentation has to be accurate, portable, fast to deploy and tolerant of the heat, dust and vibration of a live WA process precinct. ISS selects the instrument to the task and the schedule, and calibrates annually to ISO/IEC 17025.

The Leica TS16 robotic total station (±1 mm + 1.5 ppm, 1″ angle) and the Leica MS60 MultiStation are the workhorses for control, alignment and set-out, with Automatic Target Recognition that keeps the surveyor clear of exclusion zones around live lifts. For the tightest alignment — turbine couplings on a Collie unit, large bearing bores, machined seating faces — a FARO laser tracker delivers ±0.015–0.025 mm at typical working ranges for coaxiality and concentricity where a total station's accuracy is insufficient. A Leica RTC360 laser scanner captures point clouds at 2–6 mm at 50 m with a set-up under two minutes; on an outage it is the fastest route to as-built capture of opened internals, pipework and steel, and the method of choice for fit-check of replacement modules and clash detection on tie-in work.

The sequence matters as much as the kit. ISS locks scope four to six weeks out, establishes a stable control network one to two weeks before the unit comes down — while access is still clear — then captures the pre-outage baseline of as-found centrelines and clearances. During the window the survey runs in step with mechanical activity: dimensional verification after removal, alignment setting during rebuild, fit-check before installation, and flatness on cleaned foundations, with reflectorless and tracker measurement keeping technicians clear of active cranes. A final pass confirms every adjusted component is in tolerance and records the as-built condition before recommissioning, with critical results reported on the spot so the next activity is never held up by the formal report.

Key point: Scanning and total-station work are complementary on an outage, not interchangeable. The RTC360 captures the whole condition for as-built and fit-check; the total station and tracker deliver the sub-millimetre numbers the mechanical team signs against.

Standards, tolerances and compliance

Outage survey accuracy is matched to the engineering tolerance of each task, then verified against the relevant standard. The figures below are the specifications ISS works to.

Every measurement is traceable to national standards through ISO/IEC 17025 calibration certificates, and each report carries a measurement uncertainty statement. Structural and crane geometry is assessed against AS 1418.18 (crane runways), AS 4100 (steel structures) and project or OEM tolerances where they are tighter, while ISO 1101 geometric principles anchor alignment work. Where ISS flies drones for elevated as-built capture, flights run under CASA regulations by a certified remote pilot. Field work on Kwinana and remote WA sites runs under permit-controlled high-risk plant access and the Work Health and Safety (Mines) Regulations 2022 — confined-space, hot-work and working-at-heights regimes typical of the state's turnarounds, and a reason ISS field staff hold current WA mine-site passports and facility-specific inductions. No single Australian Standard prescribes turnaround alignment tolerances, so the surveyor's methodology and the traceability of the result are the real assurance, not a certificate number alone.

Why ISS for outage surveys in Perth

ISS is an independent precision surveying firm, not tied to any equipment manufacturer — which matters in a state running plant from many different OEMs across a single turnaround. We align and verify equipment from any maker using one consistent, traceable methodology, and we mobilise faster than an interstate or overseas service crew flown in for one window. For a Kwinana refinery that finds a fit-up problem on day two of a fourteen-day turnaround, the difference between a same-week Perth mobilisation and a fortnight's wait is the difference between protecting the restart and blowing it.

ISS maintains a Perth presence to engage the reliability engineers, shutdown planners and procurement teams that commission WA turnaround work, and our surveyors understand the 24-hour duty cycles that mean outage work is scheduled to the hour and the FIFO logistics of reaching Pilbara and Goldfields shutdowns. Equipment is staged and calibrated in Perth with redundant instrumentation, so a single failure never stops the line and a remote mill reline carries the same accuracy as a survey on Cockburn Sound. Cost is quoted fixed-price or as a schedule of rates after a scoping call — a limited-scope survey might run $15,000, while a comprehensive program on a major turnaround can exceed $60,000, against a single avoidable hour of lost production at $50,000–200,000.

Frequently asked questions

How quickly can ISS mobilise to an outage in Perth?

We service Perth, the Kwinana Industrial Area and the metropolitan precincts directly, and routinely mobilise within days — faster for urgent work such as a fit-up problem found mid-turnaround. Because we are not flying a crew in from an interstate or overseas service centre, we slot in-outage attendance around your shutdown calendar without a long lead time. For remote Collie, Pilbara and Goldfields outages we coordinate FIFO to match your roster cycle. The ideal booking window is four to six weeks ahead, allowing scope definition, a pre-outage site visit and crew scheduling.

Can a shutdown survey be done without extending the window?

Yes — that is the entire point. Well-planned outage survey work runs parallel to mechanical activity and stays off the critical path: the surveyor measures when an area is ready and reports before the next activity needs the result. Overruns come from late scope and missing control, both of which planning eliminates. ISS establishes the control network before the area is congested and schedules attendance against the work list so the window never waits on measurement.

What accuracy does a Perth outage survey achieve?

Rotating-equipment alignment is typically ±0.3–1.0 mm with total station and MultiStation, and ±0.02–0.05 mm for coaxiality and concentricity using a FARO laser tracker. As-built scanning is 2–6 mm at 50 m with a Leica RTC360. All instruments are ISO/IEC 17025-calibrated and every alignment deliverable carries a measurement uncertainty statement.

Which Perth operations actually need outage surveys?

Any time-bound shutdown where measurement is on the critical path or recommissioning depends on verified geometry: alumina refinery turnarounds at Alcoa Kwinana and South32 Worsley, autoclave and cell work at BHP's Kwinana nickel refinery, cement-kiln overhauls at Cockburn Cement, turbine and boiler outages at the Collie coal units, lithium-train rebuilds at Kemerton, and SAG and ball-mill relines on Pilbara and Goldfields operations reached by FIFO from Perth. If alignment is checked by tape and feeler gauge, if fit-up problems routinely surface mid-lift, or if as-built records are reconstructed after restart, an outage survey will protect your window.
