An explosion proof mobile phone for Chevron Australia has to work on two very different sites: Gorgon, on Barrow Island, a Class A nature reserve off the Pilbara coast, and Wheatstone, on the mainland at Ashburton North near Onslow. This page covers what is classified at each, how Barrow Island's quarantine rules change what can be carried in, and what the IS-04Z1 is being certified for. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · IECEx and biosecurity documentation in progress
Gorgon has three LNG trains designed for 15.6 million tonnes a year, fed by the Gorgon and Jansz-Io fields. Wheatstone adds two more trains and brings the pair to a combined 24.5 million tonnes of design capacity. Gorgon shipped its first cargo in 2016 and Wheatstone started production a year later. Barrow Island lies about 60 km off the coast and has been a Class A reserve since 1908, which is why the site is run under tight quarantine controls. Inside the fence the classified areas are what any LNG plant has: natural gas, condensate and refrigerant hydrocarbons, with the carbon dioxide injection system adding compression and monitoring points around it.
The area classification decides whether a device may be carried in. At Chevron Australia's sites the next questions are whether it can be landed on the island at all and whether it survives a roster of long days.
Items going to Barrow Island are checked so that seeds, insects and soil do not reach the reserve. A sealed IP68 handset with no open ports is simpler to clean and inspect, but Chevron's own quarantine team decides what is acceptable, and that is a separate gate from the Ex certificate.
Both plants are on the coast. Corrosion and humidity are daily conditions, and IP68 sealing together with rugged build is aimed at exactly that.
Barrow Island personnel arrive and leave by air, so spare units are not a short drive away. The 4,000 mAh battery is sized for a full shift on the plant.
A three-train plant has a very large pipe rack. Four-constellation GNSS and the 50 MP camera let a field operator send a position and a photograph with the report.
Android Enterprise and MDM management allow one device profile across Gorgon and Wheatstone, with camera and application policy set differently where site rules require.
A field operator checking a liquefaction train records readings, photographs a leaking flange and calls the control room from one device, without surrendering a radio and a separate camera at the gate.
During a train turnaround, contractor crews far outnumber the resident team. A managed handset carries the permit, the isolation list and the daily report, and can be reset when the contract ends.
Technicians checking compression and injection equipment move between gas systems and CO2 equipment in one walk. A single Zone 1 designed handset avoids changing devices between them.
Gorgon and Wheatstone are run by Chevron Australia's own operations organisation with a large contractor workforce alongside it. The notes below are what to raise with Chevron's teams, and SAMS makes no claim of any relationship with Chevron.
No. The device is pre-launch, with IECEx and ANZEx certification in progress ahead of the Q4 2026 launch. No certificate has been issued.
Yes. Quarantine inspection is a separate gate from hazardous area certification, and it applies to everything shipped to the island. Chevron's own team sets the rules.
The injection equipment sits beside gas systems, so the handset is chosen for the gas classification around it. The certificate states its exact scope, and site procedures for CO2 areas should be confirmed with Chevron's engineers.
Not automatically. The two sites have different logistics and are managed by their own teams, even where Chevron's engineering standards are shared.
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.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
