TL;DR: A drone inspection survey in Burnie puts a high-resolution UAV onto the wharf steel, ship-loaders, conveyor galleries and process plant of north-west Tasmania's busiest port without scaffold, elevated work platforms or rope-access crews. Industrial Spatial Solutions flies CASA-certified, ReOC-backed visual inspection across the Port of Burnie, Grange Resources' Port Latta pelletiser and the West Coast mills, resolving cracks, corrosion and coating breakdown to the level of a hands-on close visual inspection — and planning every mobilisation around Bass Strait freight so the aircraft lands when your shutdown opens.
Key takeaways
- A drone inspection survey in Burnie removes people from height on salt-corroded wharf steel, ship-loaders and conveyor gantries — cutting inspection time by 60-80% and eliminating the highest-risk access tasks under the Work Health and Safety Act 2012 (Tas) and WHS Regulations.
- Burnie's maritime climate is the driver: Bass Strait salt air attacks port and Port Latta marine steel far faster than inland sites, so corrosion and coating-breakdown inspection here cannot wait for an annual cycle — a UAV makes frequent re-inspection affordable.
- ISS captures imagery at 1-3 mm/pixel ground sampling distance (GSD), resolving hairline cracks, weld-toe defects and coating failure to the standard expected under AS 4100 (steel) and AS 3788 (pressure equipment external condition), with defects locatable to 20-50 mm when tied to ground control.
- Every flight runs under CASA CASR Part 101, on an ISS Remote Operator Certificate (ReOC) with licensed RePL pilots, registered aircraft and aviation-endorsed public liability cover — wind windows and exclusion zones planned around the port's live berths.
- As a guide, a single-asset Burnie drone inspection runs roughly $2,000-$6,000; the same close visual coverage by rope access on a major stack or loader can pass $30,000 once standby, access and demurrage are counted — so the payback usually lands on the first flight.
Drone visual inspection for Burnie's port and minerals industry
Burnie is north-west Tasmania's industrial gateway: the state's largest general-cargo and container port, operated by TasPorts, and the export point for Grange Resources' Savage River magnetite via the Port Latta pelletising plant, the West Coast minerals province and the region's forestry and woodchip trade. Almost every high, hard-to-reach asset in that chain — wharf superstructure, ship-loaders, conveyor galleries, the Port Latta pelletiser and marine loader, the mills at Rosebery and Renison — is exactly the kind of structure where conventional inspection access is slow, expensive and dangerous.
A drone inspection survey in Burnie solves the access problem. Instead of building scaffold against a ship-loader boom, standing down a berth to bring in an elevated work platform, or sending rope-access technicians down a conveyor gantry over Emu Bay, an ISS UAV reaches the same surfaces in minutes, flies a repeatable path, and brings the inspector a sharper view than the naked eye from a cherry picker. The aircraft is a remote-sensing tool; the engineering judgement stays with a competent person who reviews the imagery and classifies defects against the relevant Australian Standard.
This page is about visual inspection delivered specifically in Burnie and across the Cradle Coast and West Coast. It is not a replacement for the city surveying hub for Burnie or the national drone inspection survey service page — read those for the broader picture. Here the focus is narrow: what a UAV visual inspection looks like on Tasmania's salt-driven, island-logistics, high-relief north-west coast.
Where a Burnie drone inspection survey earns its place
The common thread across Burnie's assets is that height and corrosion arrive together — and the port cannot easily stand down to inspect them.
Port of Burnie and bulk handling
TasPorts' Burnie wharves carry containers, woodchips, cement, fertiliser and bulk minerals across continuous loading. Ship-loaders, conveyor runs, transfer towers and wharf superstructure combine height, salt corrosion and constant operation — precisely where a drone inspection survey removes the fall risk while keeping the berth working. A single sortie can image a ship-loader, the adjacent transfer tower and the conveyor run back to the next drive in one window, producing a complete, time-stamped photographic record rather than a scaffold campaign that closes a berth for days.
Port Latta pelletiser and marine loader
Grange Resources pumps Savage River magnetite roughly 85 km north as a slurry to Port Latta, where it is pelletised and ship-loaded. The pelletiser shell, ducting, stacks, structural steel and the marine loading facility all sit in full Bass Strait exposure. A UAV captures external condition of the pelletiser and stack surfaces and the marine loader steelwork at a controlled stand-off — feeding shutdown scope without erecting access on a hot, tall, corrosive structure.
West Coast mills and headframes
MMG's Rosebery zinc-lead-silver-gold operation has run since 1936, and Renison's tin circuit alongside it, both with mills, headframes and process structures extended and rebuilt many times over. Drone visual inspection covers headframes, mill superstructure, thickener and tank exteriors and conveyor gantries on these remote, high-relief sites without standing down the circuit — and it pairs naturally with the as-built scanning ISS already runs at these plants.
Heavy manufacturing and engineering
Burnie and nearby Wynyard host heavy fabrication, including Caterpillar Underground's mining-equipment manufacturing. Large fabrication halls, gantry cranes and tall structural steel are inspectable from a UAV without halting the floor.
How ISS delivers a drone inspection survey in Burnie
ISS follows a structured, non-contact workflow refined across mining, processing, ports and infrastructure. A single Burnie asset — a ship-loader, a stack, a transfer tower — is typically half a day on site plus one to three days of review, and for most assets it is done with the plant running.
- Scoping and risk assessment. We confirm the defects of interest (cracking, corrosion, coating breakdown, deformation), the required GSD, and whether photogrammetric geometry is needed. A JSA and a CASR Part 101 airspace assessment cover the exclusion zone around live berths, people and operating plant — and any controlled-airspace or aerodrome-proximity issues, including the proximity of Burnie Airport at Wynyard.
- Ground control (where required). If defects must be located on a 3D model or compared between inspections, ISS establishes control with Leica or Trimble GNSS and total station equipment. Georeferencing is what turns a folder of photos into a measurable, repeatable inspection.
- Flight planning. The inspection is planned as controlled passes at a fixed stand-off — typically 3-10 m — to hold a consistent GSD, with automated structure-following missions on complex geometry so coverage and overlap are guaranteed, not left to the pilot's eye.
- Data capture. The aircraft flies the mission while the payload captures high-resolution stills and, where needed, zoom detail and thermal imagery. The pilot maintains visual line of sight and the exclusion zone. Full close-range capture of a 50-60 m structure is usually complete within one to two hours.
- On-site image QA. Before demobilising, the crew checks focus, exposure, coverage and overlap against the asset map — because re-flying a missed face costs minutes on site, whereas a return mobilisation to Tasmania costs days.
- Processing and defect review. Imagery becomes a tagged image library, an orthomosaic of each face, or a textured 3D model. A competent inspector marks defects and classifies them by type and severity against the relevant standard.
- Reporting and handover. You receive a defect register with location, photographs, severity rating and recommended action, plus the raw geotagged imagery and any 3D model. On repeat inspections, defects are compared to the baseline so change is reported, not just current state. Reports typically land within three to five business days.
Equipment and what it resolves on Burnie steel
A drone inspection survey is only as good as its optics, its stability in wind, and the discipline of the flight — and Bass Strait wind discipline matters here more than almost anywhere.
ISS flies high-stability multirotor platforms carrying mechanical-shutter RGB sensors in the 20-45 MP class. At a 5 m stand-off these resolve a GSD of roughly 1-1.5 mm/pixel — fine enough to identify the hairline cracking, weld defects and early coating breakdown that drive maintenance decisions on wharf and loader steel. Obstacle sensing and precise position hold allow safe close-range work near steelwork and conductors.
For assets where stand-off cannot be reduced — the Port Latta pelletiser stack while hot, an energised switchyard, a restricted berth — a long-range optical zoom payload captures defect-level detail from a safe distance. A radiometric thermal sensor (sub-0.05 °C NETD) adds anomaly detection: overheating bearings and motors on conveyor drives, blocked or wet refractory on the pelletiser, lagging defects and electrical hot spots.
Crucially, the same ISS team that flies the UAV and aerial surveys also runs the firm's 3D laser scanning and mechanical surveys. When a drone inspection finds something that needs measuring — a bent boom chord, a settled wharf bent, an out-of-true conveyor truss — ISS brings a total station, laser scanner or photogrammetric capability to the same site without re-engaging a new contractor. Point clouds export to LAS, LAZ and E57 so the inspection becomes the front end of a complete condition and dimensional picture.
Key point: Stand-off distance, not just sensor megapixels, sets the achievable detail. A 45 MP sensor flown at 15 m resolves less than a 24 MP sensor flown at 4 m. On Burnie's port steel, the skill is flying close and steady enough — inside Bass Strait gusts and around live berths — to capture the GSD the defect actually requires.
Accuracy, standards and compliance
Two kinds of accuracy matter: how small a defect the imagery resolves, and — where geometry is captured — how precisely a defect can be located. ISS captures close-range imagery at 1-3 mm/pixel GSD, resolving crack widths down to roughly 0.5 mm subject to lighting and surface, and locates defects to 20-50 mm on a georeferenced 3D model when ground control is established. Coverage is verified at 100% of nominated faces against the asset map, not spot-checked.
The inspection itself is conducted against the standard relevant to the asset — AS 4100 for structural steel, AS 3788 for in-service pressure-equipment external inspection, AS 1418 and AS 2550 for cranes and runways such as the Burnie ship-loaders, and dam-safety guidelines such as ANCOLD where tailings or water-retaining structures are in scope at West Coast sites. ISS records the standard applied, the inspector's competency, and a measurement-confidence statement with every report.
Every UAV operation runs under CASA CASR Part 101 and the associated Manual of Standards, on an ISS Remote Operator Certificate (ReOC) with licensed RePL pilots, registered aircraft and aviation-endorsed public liability insurance. Where the inspection feeds statutory obligations under the Mineral Resources Development Act 1995 or the Work Health and Safety Act 2012 (Tas), survey-derived geometry is referenced to the national datum and ICSM SP1 standards so it is accepted by Mineral Resources Tasmania and your engineers without rework.
⚠️ Watch out: A drone inspection does not by itself satisfy every mandated inspection regime. Some pressure-equipment and crane standards still require hands-on or NDT inspection at defined intervals. Used well, a Burnie drone inspection survey extends the interval between intrusive inspections and targets them where the imagery shows they are needed — it does not blindly replace them.
Why ISS for drone inspection in Burnie
Tasmania is a smaller market than WA or Queensland, but it is high-value and technically demanding, and it rewards a provider who plans around the island's logistics rather than fighting them. Because Tasmania is an island, ISS plans every mobilisation around Bass Strait freight and the Spirit of Tasmania crossings into Devonport, so the aircraft and crew land in line with your shutdown or maintenance window — not after it. For West Coast sites such as Rosebery, Renison and Savage River, crews mobilise direct with backup equipment and the ability to work self-sufficiently on remote, wet, high-relief terrain.
ISS is an independent industrial surveying firm — not tied to any aircraft brand or maintenance contractor — so the inspection serves your asset, not an upstream agenda. Drone orthophotos and defect imagery are typically returned within 24-48 hours of flight, with full defect registers in three to five business days. As a guide, a single-asset Burnie drone inspection runs roughly $2,000-$6,000 depending on height, complexity and deliverable depth; a thermal payload adds around $800-$1,500; controlled-airspace or live-berth coordination adds $500-$2,000. Every job is fixed-price quoted after scoping, with mobilisation to Tasmania set out transparently up front.
Frequently asked questions
Can a drone inspection survey be flown around Burnie's live berths and Port Latta loader?
Usually, yes. The capture is non-contact, and most live port and process assets can be inspected without standing down operations, provided an exclusion zone can be maintained around people, vessels and operating plant. Energised switchyards and hot surfaces such as the pelletiser stack are flown from a safe stand-off using an optical zoom or thermal payload. ISS scopes the exclusion zone and CASR Part 101 airspace requirements — including Burnie Airport proximity at Wynyard — before mobilising.
How does ISS handle Bass Strait wind and salt corrosion when inspecting?
Wind is planned, not gambled on: flights are scheduled for calmer Bass Strait windows, and high-stability platforms with precise position hold maintain a consistent stand-off close to the steel. Salt corrosion is exactly why frequent UAV inspection makes sense here — coating breakdown and section loss on wharf and marine steel progress far faster than inland, and a drone makes affordable, repeatable re-inspection practical instead of an annual scaffold campaign.
How quickly can ISS get a drone crew to Burnie?
Because Tasmania is an island, mobilisation is planned around freight and ferry timing rather than a same-day drive. For scheduled work we lock crew and calibrated equipment to your shutdown window, with typical lead times of a few days to a week. For ongoing port or monitoring programmes we hold equipment in-region during the campaign, so response is much faster.
What do we receive from a Burnie drone inspection survey?
A defect register with each defect located, photographed, severity-rated and matched to a recommended action, plus the full geotagged image library. Where required, you also receive an orthomosaic of each face, a textured 3D inspection model with defects pinned in 3D, a thermal report, and — on repeat inspections — a comparison report showing change against the previous baseline. Reports are usually delivered within three to five business days.
