North Hub project
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.
Indonesia's offshore oil and gas includes the Kutai Basin off East Kalimantan, where the Makassar Strait North Hub project, operated by the Searah venture of Eni and Petronas, is building a floating production unit. Platforms, FPSOs and drilling rigs are classified hazardous areas. This page explains what to look for in an ATEX and IECEx smartphone for Indonesian offshore oil and gas fields, and where the IS-04Z1 stands against that list today.
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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. 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.
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.
Crews and equipment move by supply vessel or helicopter, so equipment is normally certified and approved before mobilisation.
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 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.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Indonesian offshore oil and gas fields. Offshore reviewers working on projects such as the Makassar Strait North Hub would expect certificate evidence matched to the marking, with its schedule of conditions. The IS-04Z1 evidence is in progress. A dual ATEX and IECEx route suits an international joint venture such as Searah and its contractors.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
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.
