Monsoon seasons affect access and weather windows.
The Tangguh field in Bintuni Bay, West Papua, has estimated proven gas reserves of 4.4 trillion cubic feet, with annual output hoped to reach about 7.6 million tonnes of liquefied natural gas. Platforms, FPSOs and drilling rigs are classified hazardous areas. An explosion proof mobile phone distributor in Indonesian offshore oil and gas fields would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Indonesian offshore oil and gas fields has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Indonesian offshore oil and gas fields: Drilling rigs, Wellhead areas, Offshore production platforms | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Indonesia Offshore Rigs. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

Monsoon seasons affect access and weather windows.
Reports describe an FPSO designed for 1 billion standard cubic feet of gas a day, in about 2,000 metres of water, with first steel cut in July 2026 and commercial production targeted for the fourth quarter of 2028.
The East Natuna gas field in the South China Sea is believed to hold about 46 trillion cubic feet of proven gas, one of the biggest reserves in Southeast Asia, though development has been long delayed.
The Batam Industrial Development Authority, now BP Batam, was created by a 1973 presidential decree to manage a 415 square kilometre industrial complex for heavy industry, where previously only Pertamina was based.
The Masela block, east of Timor island, was described as likely to become Indonesia's biggest deepwater gas project, with over 10 trillion cubic feet of gas and an estimated 14 to 19 billion dollars of investment.
Indonesia was a significant oil exporter in the 1980s, but since 2000 consumption has risen while production has fallen, so offshore and mature-field drilling carries national importance.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Indonesian offshore oil and gas fields. On platforms, FPSOs and rigs, explosion-proof is shorthand for several concepts. Flameproof Ex d protects fixed junction boxes and motors, while a handheld carried around wellheads and process decks relies on intrinsic safety. The operator's hazardous-area drawings define which concept is accepted where.
A distributor for Indonesian offshore oil and gas fields would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
Likely candidates are offshore production platforms, fpso process and storage areas, drilling rigs, wellhead areas. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Indonesian offshore oil and gas fields.
Usually not into classified areas. Offshore installations normally restrict personal electronics to safe areas unless a device carries the certification the operator accepts for the relevant zone and gas group. Ask the operator for its portable-electronics policy before mobilising.
Warm temperatures, high humidity, salt spray and heavy squalls are typical, so devices usually need good ingress protection, corrosion-resistant ports and sealed battery compartments. Check the rating against the rig's environment and the operator's specification.
Yes, because monsoon seasons affect access and weather windows, so spares and crew changes may be delayed. Plan extra devices and charging in a safe area. Salt and humidity also matter for seals. Confirm logistics with the operator's offshore team.
