Offshore logistics
Crews and equipment move by supply vessel or helicopter, so equipment is normally certified and approved before mobilisation.
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. 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. If you are specifying an explosion proof 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.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned 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: Offshore production platforms, FPSO process and storage areas, Drilling rigs | 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.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.

Monsoon seasons affect access and weather windows.
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.
About 80 per cent of people in the Natuna islands are of Malay origin, and Terengganuan Malay is used alongside Indonesian, which matters for hiring and site communication near the offshore gas area.
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.
“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 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.
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.
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.
