Coastal LNG plants in extreme heat
Karratha, Onslow, Darwin and Gladstone are hot, humid or salt-laden. The marking target is II 2 G Ex ib IIC T4, with IP68 sealing and rugged build for the environment.

Explosion proof mobile phone for oil and gas in Australia
Australia's oil and gas sector is built mostly around LNG export, and an explosion proof mobile phone for Australia has to suit three different settings: offshore platforms and floating facilities, coastal LNG plants, and the onshore coal seam gas and Cooper Basin gas fields. This page maps the operators and sites in each, and shows where the IS-04Z1 Zone 1 design target applies. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.

Explosion proof mobile phone sites in Australian oil and gas
Western Australia and the Northern Territory hold the offshore-fed LNG plants: Woodside at Karratha and Pluto, Chevron at Barrow Island and Onslow, INPEX at Darwin and Shell's Prelude vessel offshore. Queensland's LNG comes from coal seam gas, taken from thousands of wells across the Surat and Bowen basins to Curtis Island at Gladstone, where QCLNG, GLNG and Australia Pacific LNG each run a plant. Santos operates the Moomba gas plant in the Cooper Basin in South Australia. Refineries and fuel terminals, including Viva Energy at Geelong and Ampol at Lytton, make up the downstream end. The hazard is similar across all of them, but the working patterns are not.

Built for local conditions
What each oil and gas setting does to a handset
The classification is much the same across the sector. The working pattern is not, and that is what decides which handset features matter at a given site.

Offshore crews on rotation
Platform and vessel crews fly or sail in on fixed rotations, so devices stay on the facility and are handed from crew to crew. MDM lock and wipe handle each handover.
Thousands of wells in Queensland
Coal seam gas fields are spread across large areas. Technicians visit well sites and compressor stations alone. Four-constellation GNSS gives a position and the 50 MP camera records the well.
Mixed contractor workforces
Worley, Monadelphous and Clough, among others, bring crews to turnarounds. Android Enterprise management lets operators enrol and retire contractor handsets quickly.
Offshore regulation
Facilities in Commonwealth waters are overseen by NOPSEMA, so a new device type is considered within each operator's safety case, which is the operator's decision.
Use cases · Oil and gas
Where the IS-04Z1 goes to work.
LNG01
Train turnaround crews
A planned train shutdown brings hundreds of contractors for weeks. Enrolled handsets carry permits and job packs and can be wiped at the end of the work.
Upstream02
Gas field and compressor station visits
A coal seam gas technician driving between well sites needs a position, a photograph and a call back to the control room from the same device.
Offshore03
Platform and FPSO rounds
On a platform or floating facility, an operator records readings and reports defects without leaving the classified area.
Work pattern and buying
How work is organised, and what buyers ask
Each operator has its own engineering and procurement process, and there is no single approval route for the sector. These are the points to raise with each company's own teams. SAMS makes no claim of any relationship with any operator named on this page.
- Turnarounds
- Liquefaction trains are shut for planned maintenance on a cycle set by the operator. These periods have the most contractors and the highest demand for managed handsets.
- Remote logistics
- Offshore and island sites limit what can be shipped in a hurry. Ask each operator how spares and replacement handsets will reach site.
- Supplier approval
- Operators set their own supplier and equipment requirements. SAMS has not been through any operator's process; ask the procurement and HSE teams for the current documents.
- Evidence
- IECEx certificate and its scope, the ANZEx equivalent, and the ACMA RCM radio marking. All in progress ahead of the Q4 2026 launch.
- Company pages
- See the explosion proof phone for Woodside Energy, for Chevron Australia, for INPEX at Ichthys and for Shell Australia.
Questions · Oil and gas
Frequently asked questions
Is the IS-04Z1 certified for oil and gas use in Australia yet?
No. The device is pre-launch, with IECEx and ANZEx certification in progress ahead of the Q4 2026 launch. No certificate has been issued.
Does coal seam gas have a different classification from LNG plants?
The hazard is natural gas in both, but field equipment is usually classified differently from a liquefaction train. Each site's drawings decide, and the certificate scope states where the handset may go.
Does one device cover offshore and onshore assets?
That is the design intent, because both involve Zone 1 gas areas. Offshore use also depends on the operator's safety case.
Do the operators share one approval process?
No. Each runs its own engineering review, though all can refer to the same IECEx certificate.
Enquiry · Oil & Gas
Ask about the IS-04Z1 for Oil & Gas, Australia
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Australia. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
