Ex-Proof Smartphone in UAE Offshore
Upper and Lower Zakum together hold around 50 billion barrels of oil in place and form the second largest offshore oilfield in the world. Upper Zakum, discovered in 1963 and on stream since 1977, is operated as part of ADNOC Offshore (formerly ZADCO), with offshore output handled at island facilities such as Das Island and Zirku Island. This page explains what to look for in an Ex-proof smartphone for UAE offshore fields, and where the IS-04Z1 stands against that list today.

WhereUAE Offshore
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for UAE offshore fields: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Local conditions · UAE offshore fields
Conditions in UAE offshore fields that affect handheld equipment
Access
Das Island lies about 160 km north-west of the UAE mainland and is staffed by about 6,000 oil and gas personnel on a rotational schedule, so access is by operator-controlled sea and air transport.

UAE offshore fields: projects and investment
ADNOC Drilling has been contracted to supply island rigs for wells on existing and new artificial islands at Zakum, with delivery expected from 2026.
UAE offshore fields: infrastructure
Replacement of a 125 km oil pipeline from Umm Lulu to Zirku Island has been awarded as an offshore project, so subsea and island pipeline work is under way.
UAE offshore fields: projects and investment
Zakum's artificial islands suit extended-reach drilling, and the five longest wells in the world are reported to have been drilled there.
UAE offshore fields: geography and layout
Upper Zakum lies about 84 km north-west of the Abu Dhabi islands, so it is a boat or helicopter journey from the mainland.
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 UAE offshore fields. A marking check offshore would compare each platform or island area's zone, gas group and temperature class with the device marking. Hydrocarbon production areas may be Zone 1, and gas groups depend on the product. The IS-04Z1 target, II 2 G Ex ib IIC T4, is in progress and not certified.

Specifying an Ex-proof smartphone for UAE Offshore
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · UAE Offshore
Frequently asked questions
Can we buy an Ex-proof smartphone in UAE Offshore today?
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.
What does an Ex-proof smartphone in UAE Offshore cost?
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.
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 UAE offshore fields would use it?
Likely candidates are offshore production platforms and islands, island processing and terminals, platform and subsea pipelines, marine loading terminals. 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.
Why are artificial islands used at Zakum?
Artificial islands let operators drill many wells and handle production from fixed land-like platforms, and they favour extended-reach drilling. ADNOC Drilling has been contracted for new island rigs, so contractor numbers on the islands may rise. Confirm access and equipment rules with ADNOC Offshore.
What corrosion issues affect devices on Zirku or Das Island?
Salt-laden humid air is typical, so look for sealed housings, corrosion-resistant connectors and a stated ingress protection rating. Rinse and dry devices as the manufacturer advises, and carry spares, as resupply is by sea or air.
Does the offshore climate affect a handheld?
The offshore setting is hot and humid with salt-laden air; Zirku Island summers reach 35 to 45 degrees C. The IS-04Z1 is designed to IP68 with a 4,000 mAh battery, but no heat or salt limits are published. Ask for the datasheet and agree use conditions with the operator.
