Personnel and spares move by helicopter and supply vessel, so a failed device may take days to replace.
Indonesia's offshore oil and gas is spread across the Natuna area, the Java Sea and the Kutai Basin off East Kalimantan, where the Mahakam block is run by Pertamina Hulu Mahakam. Platforms and FPSOs are Zone 1 environments for process, drilling and maintenance crews. This page explains what to look for in an intrinsically safe smartphone for Offshore Indonesia, 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 Offshore Indonesia: 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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Offshore Indonesia. 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.
Personnel and spares move by helicopter and supply vessel, so a failed device may take days to replace.
Offshore units for fields such as Belanak in the Natuna Sea have been fabricated at yards in Batam before sailing out.
The Arun field in Aceh produced gas from the 1970s and is now largely depleted, and nearby operations included the North Sumatra offshore gas field, with assets passing to Pertamina in 2015.
The Abadi design uses a gas FPSO that treats the gas before sending it by subsea pipeline to an onshore LNG plant with two trains, and captured CO2 is to be reinjected into the well.
Ranai Airport is among the regency's main transport points, so crew changes and urgent spares for offshore gas work would typically move by air and then by supply boat; confirm routes with the operator.
INPEX operates the offshore Masela block's Abadi gas project with 65%, alongside Pertamina at 20% and Petronas at 15%, targeting about 9.5 million tonnes of LNG a year and up to 35,000 barrels of condensate a day.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Offshore Indonesia. Offshore crews on production platforms and FPSOs run permit-to-work rounds in tight, crowded decks. A handheld designed for intrinsic safety could hold checklists, photographs and gas-test records in one device, once certified and accepted by the operator. Staff on production platforms and FPSOs also move frequently between decks, so one device that need not be swapped at each boundary saves time.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Likely candidates are wellhead and production platforms, fpsos and floating production units, drilling and workover areas, gas processing modules. 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.
Usually yes for classified areas. Operators normally require equipment certified for the zone, gas group and temperature class of the location, supported by a permit to work. Confirm the exact certification marks the platform accepts for portable devices.
Indonesian is the national language and Malay is widely spoken in areas such as Natuna, while operators typically run safety briefings in English as well. Check that device interfaces and any emergency procedures can be used in the languages your crew needs.
Heat, humidity and salt spray are constant, and monsoon seasons affect sea state and crew changes. Check seals, ports and charging contacts for corrosion. IP68 is useful but is not explosion protection. Confirm approved devices with the operator.
