The Mahakam block, in East Kalimantan, was reported to supply around 30 percent of Indonesia's natural gas, about 1.7 billion cubic feet a day in mid-2013, plus condensate. Platforms, FPSOs and drilling rigs are classified hazardous areas. If you are specifying an IECEx mobile phone for Indonesian offshore oil and gas fields, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Indonesian offshore oil and gas fields: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

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.
A short profile of the site and the kinds of classified area that matter for portable equipment.
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 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.
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.
Indonesia is said to have around 60 sedimentary basins, of which only 22 have been explored and exploited, so offshore drilling remains an active frontier for new fields.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Indonesian offshore oil and gas fields. A project led by international partners naturally draws on IECEx documentation alongside local rules. The certificate of conformity and schedule of conditions would be checked before mobilisation. For the IS-04Z1 those are targets, not issued, so no offshore specification can rely on them yet.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Rigs are normally supplied from shore bases by supply boat or helicopter, so deliveries follow set schedules and weight limits. Plan spare batteries and chargers well ahead, and confirm customs and radio type-approval needs for each landing point.
Rigs typically follow the standards of their flag state or classification society, often IECEx or ATEX based, together with the operator's own rules. Confirm with the rig operator which certification marks it accepts for portable devices and how permits to work are issued.
Crews and equipment move by supply vessel or helicopter, so replacing or approving a device on the platform is slow. Operators therefore expect certification and approval onshore. Ask the operator or its contractor for the approval route. Confirm with them.
