More about Offshore Indonesia that matters for portable equipment
Offshore Indonesia: geography and layout
Natuna Regency, the northernmost part of Riau Islands Province, has only 1,984 sq km of land within a total area of about 264,198 sq km, so almost all of it is open sea.
Offshore Indonesia: industry on the ground
The Tangguh field in Bintuni Bay, West Papua, was estimated to hold 4.4 trillion cubic feet of proven gas, with annual LNG output expected to reach about 7.6 million tonnes.
Offshore Indonesia: infrastructure
Indonesia produced about 450.8 million tonnes of oil equivalent of energy in 2019, and its total primary energy supply rose by nearly 60 percent between 2000 and 2021.
Offshore Indonesia: background
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 term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Offshore Indonesia. A marking check offshore would match the label to the zone of a wellhead, drilling area or processing module, with the right gas group and temperature class. Gas streams may include hydrogen-bearing components, so reviewers read the drawings. The target marking is II 2 G Ex ib IIC T4, unapproved.

Questions · Offshore Indonesia
Frequently asked questions
Can we buy an Ex-proof mobile phone in Offshore Indonesia today?
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.
What does an Ex-proof mobile phone in Offshore Indonesia cost?
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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
Which areas at Offshore Indonesia would use it?
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.
Is intrinsically safe the same as explosion proof?
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.
Do offshore platforms in Indonesia require certified phones in hazardous areas?
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.
What language support is available for contractors offshore Indonesia?
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.
Does the sea affect handset choice offshore Indonesia?
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.
