Outage Surveys — Burnie

TL;DR: A shutdown survey in Burnie is precision measurement delivered inside the fixed window when a north-west Tasmanian port asset, pelletising plant or mine concentrator is taken offline for maintenance. With the Port of Burnie running continuous bulk and container handling, Grange Resources' Port Latta pelletiser and ship-loader, and the West Coast mills at Rosebery and Renison all working to tight outage clocks, every hour offline costs real money — so Industrial Spatial Solutions plans the outage survey to the hour, executes to sub-millimetre tolerances, and keeps measurement off your critical path.

Key takeaways

• A shutdown survey Burnie operators rely on is scoped to a specific, time-bound window — a ship-loader or wharf-conveyor outage at the Port of Burnie, a pelletiser and marine-loader overhaul at Port Latta, a mill reline at Rosebery or Renison — where the asset earns nothing until it restarts.
• ISS achieves ±0.3–1.0 mm alignment, ±0.02–0.05 mm coaxiality with a FARO laser tracker, and 2–6 mm at 50 m laser-scan accuracy using Leica MS60 MultiStation, TS16 total stations and RTC360 scanners, all calibrated to ISO 17025.
• Bass Strait freight is the Tasmanian variable: trackers and scanners must be planned across the strait into Devonport with real lead time, so booking 4–6 weeks before the outage date is non-negotiable for north-west sites, not optional.
• Burnie's port and west-coast assets are mostly ageing, salt-exposed and repeatedly modified, so original drawings are usually missing or wrong — comprehensive scanning during the outage doubles as the design basis for the next one.
• Work is referenced to GDA2020/AHD on ICSM specifications and aligns with the Mineral Resources Development Act 1995 (Tas) and the Work Health and Safety Act 2012 (Tas), with crane and structural results assessed against AS 1418 and AS 4100.

The shutdown survey in Burnie and north-west Tasmania

An outage survey is the dimensional control, alignment and as-built measurement work carried out while an industrial asset is shut down for a defined maintenance window. Around Burnie the term covers a ship-loader or conveyor outage on a working wharf, a pelletiser and rotary-equipment overhaul at Port Latta, and a mill reline or crusher change-out at a West Coast mine — anywhere a line is deliberately stopped and has to come back within tolerance before it can earn again.

What makes Burnie distinct is not the survey discipline but the operating context. North-west Tasmania's industrial value sits in a tight cluster of mature, tolerance-critical assets — the deep-water Port of Burnie operated by TasPorts, Grange Resources' Savage River magnetite mine and its Port Latta pelletising plant, the heavy manufacturing base around Burnie and Wynyard, and the underground mines of the West Coast minerals province — and almost all of them are supplied, crewed and shipped through Burnie. A shutdown survey here is therefore an island logistics exercise as much as a measurement one: the window is fixed, the specialist kit may have to cross Bass Strait into Devonport, and Bass Strait weather can close a road or a wind-window before the crew is even on site.

The other defining feature is the port itself. The Port of Burnie is Tasmania's largest by throughput, and its ship-loaders, wharf conveyors and bulk-handling structures cannot be stopped lightly — when a loader is down, vessels sit on demurrage and the island's freight task has no easy overland alternative. That puts an unusually hard premium on getting the outage survey planned, scoped and executed to the clock.

Key point: A shutdown survey Burnie industry can depend on is engineered around two constraints at once — the outage clock and the strait. A method that is more accurate but two hours slower can blow the window, and a tracker that has not been freighted to Devonport in time is useless no matter how accurate it is. ISS plans for both before the first day of the outage.

Where outage surveys apply across the Cradle Coast and West Coast

The same five-phase outage protocol applies at every site, but the equipment and the survey-critical activities change with the plant. The table maps the principal outage workloads serviced through Burnie.

Port and marine-loader outages

The Port of Burnie's ship-loaders and the Port Latta marine loader are the highest-pressure outage assets in the region. A ship-loader is a large slewing, luffing machine running on a crane rail, and an outage is often the only chance to survey the runway for gauge and straightness, check the boom and conveyor geometry, and verify replacement modules will land before the crane is committed. At Port Latta the pelletiser, rotary equipment and marine structures are surveyed for shell ovality, axis straightness and roller skew so the unit runs true — a misaligned rotary kiln or pelletiser sheds several percent of thermal efficiency and chews through tyres and rollers prematurely. The constant salt exposure on both sites means crane-rail and structural geometry rarely stays where the last drawing put it, so the outage scan is the only reliable record.

Mineral-processing and mine shutdowns

At Rosebery, Renison and the Savage River concentrator the mill reline window is short and unforgiving: girth-gear and pinion alignment, trunnion and bearing checks, and conveyor and crusher work all sit on the critical path. A pre-outage fit-check scan of a replacement mill section, a crusher liner set or a Port Latta ship-loader module confirms it will fit before the lift is made — the single most effective way to keep a remote, wet West Coast shutdown from slipping.

Method and equipment for north-west Tasmanian outages

Outage survey equipment has to be accurate, portable, fast to deploy and tolerant of heat, dust, vibration and salt air — and in Tasmania it has to survive the freight. ISS selects the instrument to the task and the schedule, then plans the kit list around Bass Strait lead times into Devonport.

• Leica TS16 robotic total station and MS60 MultiStation — ±1 mm + 1.5 ppm distance, 1" angle. The workhorses for control, alignment and set-out. The MS60 combines angle, distance and scanning in one instrument, which matters when setup time is the constraint inside a port or pelletiser shutdown, and Automatic Target Recognition keeps the surveyor clear of active lifts on a live wharf.
• Leica RTC360 3D laser scanner — 2–6 mm at 50 m, full setup under two minutes. The fastest route to comprehensive as-built capture of ship-loader steel, conveyor galleries, pelletiser internals, mill internals and clearance envelopes, and the method of choice for fit-check of replacement modules and clash detection on tie-in work.
• FARO laser tracker — ±0.015–0.025 mm at working range. The instrument for coaxiality, concentricity and machined-face checks on large bearing bores, drive trains and rotary-equipment seats where a total station's accuracy is insufficient — and for the precision assembly work at the Burnie and Wynyard manufacturers.
• Reflectorless and portable control — reaches hot, high or inaccessible points without target placement, and quickly recovered control targets serve repeated measurement cycles across a multi-day outage.

A stable 3D control network is set out around the work area before the outage starts, with reference points positioned to survive scaffolding, crane movements and demolition. Establishing control before the area is congested is the single biggest time-saver during the outage itself — and on a decades-old wharf or a continuously modified pelletiser, where steelwork has accreted over generations, it is also the hardest, which is exactly why it is done early.

Key point: Scanning and total-station work are complementary on an outage. The scanner 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. Using one where the other belongs either wastes window time or undershoots the tolerance.

Accuracy and standards

Outage survey accuracy is matched to the engineering tolerance of the task and verified against the relevant standard.

All instruments are calibrated to ISO 17025 and measurements are traceable to national standards, with uncertainty statements supplied alongside alignment deliverables. Deliverables are referenced to GDA2020 and the AHD (Tasmania) vertical datum on ICSM specifications so they integrate cleanly with client engineering and GIS systems. Crane and structural results — including ship-loader runways and wharf steel — are assessed against AS 1418 for cranes and runways and AS 4100 for steel structures, or OEM tolerances where they are tighter. Mine-site shutdown work sits within the Mineral Resources Development Act 1995 (Tas) administered by Mineral Resources Tasmania, and every field crew works to the Work Health and Safety Act 2012 (Tas) with current confined-space, working-at-heights and site-specific certifications. UAV work supporting an outage — stockpile reconciliation, structural inspection over water — is run under CASA Part 101.

Why ISS for shutdown surveys in Burnie

North-west Tasmania's outage market is small but technically demanding, and it punishes generalist providers. The port, the Port Latta pelletiser and the West Coast mills need crews who understand port-side tolerances, corrosive continuous-operation environments and the narrow maintenance windows these assets allow — and who can get the right instrument across Bass Strait in time to use it.

• The window is the project constraint. ISS locks scope 4–6 weeks out, establishes control before the area is congested, and schedules attendance against the work list so measurement is ready the moment an area is — never before, never after. We carry redundant instrumentation so a single equipment failure never stops the line, which matters most when there is no second crew a short drive away.
• Island-aware, Devonport-routed logistics. Specialist trackers and scanners are freighted across the strait with the lead time that requires, planned around the Spirit of Tasmania crossings into Devonport and Bass Strait freight. We do not promise overnight mobilisation of kit that has to cross water, and we say so up front rather than discovering it on day one of your outage.
• Port and heavy-industry experience. We have worked ship-loaders, wharf conveyors, crane runways, rotary pelletising and kiln equipment and minerals-processing mills, and we know that salt-exposed, repeatedly modified assets cannot be trusted to old drawings — which is why scanning is built into the scope rather than bolted on.
• Independent of any OEM. We align and verify equipment from any manufacturer using consistent methodology, and feed verified geometry straight into recommissioning sign-off.
• Critical results reported on the spot. Anything a lift or a coupling decision depends on is reported verbally and in writing as it is measured. The formal report — issued within 5–10 business days — never holds up the restart or the next vessel.

This is the same outage discipline described on our outage survey service page, delivered with the island logistics and port-and-minerals knowledge set out across our Burnie and north-west Tasmania surveying work.

Frequently asked questions

How far ahead do we need to book a shutdown survey in Burnie?

Four to six weeks before the outage date, and in north-west Tasmania that lead time is firmer than on the mainland. It allows scope definition, a pre-outage site visit, safety documentation, crew scheduling and — critically — Bass Strait freight of any specialist tracker or scanner into Devonport. Late bookings risk unavailable crews, rushed methodology, freight that misses the window, and lost outage hours on a wharf where a stopped ship-loader is already costing demurrage.

Can the outage survey be done without extending our window?

Yes — that is the entire point. Well-planned shutdown 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. The Tasmanian addition is freight planning, which we treat as part of the schedule, not an afterthought.

What accuracy do you achieve during a port, pelletiser or mill outage?

Alignment work is typically ±0.3–1.0 mm with total station and MultiStation, and ±0.02–0.05 mm for coaxiality and concentricity using a laser tracker — the range that covers Port Latta pelletiser and rotary equipment, ship-loader crane rails at the Port of Burnie, and Rosebery and Renison girth-gear and pinion sets. As-built scanning is 2–6 mm at 50 m. All instruments are ISO 17025 calibrated, with uncertainty statements on alignment deliverables.

Do you have experience with port ship-loaders and rotary pelletising equipment?

Yes. Our surveyors have worked the survey requirements specific to slewing and luffing ship-loaders, crane runways and wharf steel, rotary kilns and pelletisers — runway gauge and straightness, shell ovality and axis alignment, roller and tyre geometry, and heritage-structure deformation monitoring — within the safety constraints of live, salt-exposed continuous-operation sites and the narrow shutdown windows these assets allow.
