Fabrication in Batam
Offshore units for fields such as Belanak in the Natuna Sea have been fabricated at yards in Batam before sailing out.
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. 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. Distribution partners for Offshore Indonesia are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Offshore Indonesia has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
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 |

| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |
| Accessories | Chargers and cases certified with the device | Defined at certification |

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.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
Offshore units for fields such as Belanak in the Natuna Sea have been fabricated at yards in Batam before sailing out.
Heat, humidity and salt spray are constant, and monsoon seasons affect sea state and crew changes.
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.
Natuna had about 84,900 inhabitants in 2025, around 80 percent of Malay origin, and Indonesian and local Malay are the main languages, which helps visiting crews working with local contractors.
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.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Offshore Indonesia. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
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.
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.
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Offshore Indonesia.
Seas and weather vary through the year, with monsoon periods affecting boat and helicopter schedules, so deliveries of spares can be delayed. Devices should be rated for humidity, salt and rain, and spares should be carried to cover a longer supply gap.
Typically by air to Ranai on Natuna Island and then by supply boat or helicopter to the installation, though routes depend on the operator. Check the operator's mobilisation instructions and baggage limits for electronic equipment well before travel.
Because personnel and spares move by helicopter and supply vessel, replacement can take days. Plan spare units and offline-capable apps. The operator may require approval before mobilisation. Confirm logistics with the operator's offshore team.
