Ex-Proof Mobile Phone in Indonesia Offshore Rigs

The Masela block, east of Timor island, was described as likely to become Indonesia's biggest deepwater gas project, with over 10 trillion cubic feet of gas and an estimated 14 to 19 billion dollars of investment. Platforms, FPSOs and drilling rigs are classified hazardous areas. This page explains what to look for in an Ex-proof mobile phone for Indonesian offshore oil and gas fields, and where the IS-04Z1 stands against that list today.

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 Indonesian offshore oil and gas fields. An offshore marking check would read the zone for each deck, wellhead area or process module against the label. Hydrocarbon gas with some hydrogen-bearing streams may appear, so reviewers read the actual drawings. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, which is unapproved.

Questions · Indonesia Offshore Rigs

Frequently asked questions

Can we buy an Ex-proof mobile phone in Indonesia Offshore Rigs 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 Indonesia Offshore Rigs cost?

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.

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 Indonesian offshore oil and gas fields would use 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.

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.

What logistics should I plan for rig crew change and equipment supply?

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.

Which hazardous-area standards usually apply on offshore rigs working in Indonesian waters?

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.

Why must offshore handsets be approved before mobilisation?

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.
