An explosion proof mobile phone for Cheniere Energy in the United States has to work at two Gulf Coast liquefaction sites: Sabine Pass in Cameron Parish, Louisiana, and Corpus Christi in San Patricio County, Texas. This page is for operations, HSE and telecoms teams at those terminals and for the contractors who keep expanding them. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · certification programme in progress
Sabine Pass Liquefaction in Cameron Parish, Louisiana, has six operating trains with a combined capacity of about 30 million tonnes a year, fed by the Creole Trail Pipeline. Cheniere has filed with FERC for a Stage 5 expansion there, designed for roughly 20 million tonnes a year, with a new 48-inch feed pipeline of about 5.3 miles from Jefferson County, Texas. That expansion is a proposal, not a built plant. Corpus Christi Liquefaction sits on the La Quinta Ship Channel on the north shore of Corpus Christi Bay, on a site of about 1,000 acres. It began with three trains of roughly 5 million tonnes a year each, and the Stage 3 expansion, sanctioned in June 2022, adds seven midscale trains of about 1.49 million tonnes a year each, the first of which began producing LNG in December 2024. Two further midscale trains are under construction for 2028. Gas arrives through Cheniere’s own 21.5-mile, 48-inch pipeline from near Sinton, which connects to Tennessee Gas, Tejas, Transco, NGPL and Enterprise systems.
A liquefaction site is compact, heavily instrumented and very high-consequence. It is also a place where a new train is often being built next to one that is running.
When new trains are being tied in, one fence encloses both construction and operations. Android Enterprise management lets an owner issue a different profile to commissioning crews than to operators, and withdraw it when the work ends.
A handset on an LNG terminal should sit beside the personal gas monitor, not stand in for it. Bluetooth pairing to a detector is part of the design intent and the detector still carries its own certification.
A 50 MP camera produces an image of a gland, a flange or a tag that is clear enough to attach to a work order, and a console setting can disable the camera in areas where photography is restricted.
Both terminals sit at the coast. IP68 construction is designed for rain, washdown and dust, and the 4,000 mAh battery is specified to last a shift without a trip back to the safe area.
We have not verified a Cheniere vendor-registration route and do not describe one. LNG terminals sit under FERC siting and PHMSA safety rules, plus the operator’s own standards, so the questions are about evidence.
Ask the terminal’s electrical authority which classified areas the device must enter and whether they are drawn in Class and Division or zone terms.
Decide whether contractors are issued managed handsets or bring their own, and whether construction and operating areas use different policies.
Agree where spare units and chargers are held and who is allowed to open or repair a certified device.
No. SAMS has no order, pilot or supply relationship with Cheniere. This page uses Cheniere’s published site information to describe what an LNG terminal asks of a handset.
No. It is a proposal that Cheniere has submitted to FERC. It is mentioned here because expansion work, if approved, would bring a new contractor population to a site that already has one.
Only if the area classification and the site rules say so, and only a device certified for that area. Cryogenic hazards are separate from ignition risk; the operator’s procedures govern both.
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 United States. 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.
