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 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. This page explains what to look for in a hazardous area mobile phone 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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Zone | 0, 1 or 2 for gas; 20, 21 or 22 for dust | Designed for Zone 1 and Zone 21 |
| Gas group | IIA, IIB or IIC | IIC (target) |
| Area drawing | The operator's own classification drawing | Decided by the site operator |
| 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.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Crews and equipment move by supply vessel or helicopter, so equipment is normally certified and approved before mobilisation.
Monsoon seasons affect access and weather windows.
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 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 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.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Indonesian offshore oil and gas fields. Offshore platforms, FPSO process and storage areas, drilling rigs and wellheads are classified hazardous areas. The operator and its facilities contractors classify them, not SAMS. A buyer should request the zone drawings for the specific asset before comparing equipment markings.
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.
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
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.
