ADNOC Onshore runs the desert oil fields of Abu Dhabi: Asab, Bab, Bu Hasa, Sahil and Shah, linked by a pipeline network to the Jebel Dhanna terminal. This page is for the HSE, operations and telecoms teams in the United Arab Emirates who need an explosion proof mobile phone for wellpads, gathering stations and crude receiving plants spread over a very large area. The IS-04Z1 is designed for Zone 1 and Zone 21 and is being certified ahead of its Q4 2026 launch. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · certification and vendor documentation in progress
ADNOC Onshore operates five fields, Asab, Bab, Bu Hasa, Sahil and Shah, connected by more than 450 km of pipeline to storage and shipping at the Jebel Dhanna terminal. Habshan is both a producing area and the start of the Abu Dhabi Crude Oil Pipeline, which carries crude to Fujairah outside the Strait of Hormuz. The work is dispersed: wellpads, flowlines and oil-gas separation plants sit kilometres apart in open desert, and an operator's day is largely spent in a vehicle between them. Contract awards in 2020 for flowlines and wellhead installations at Asab, Sahil and Bab, and for a bypass at the Jebel Dhanna and Fujairah crude receiving stations, show how much of the daily work is construction and modification run by contractors alongside operations.
Onshore work puts a handset through heat, sand and distance rather than salt. Four things decide whether it is still carried on the second month of a campaign.
Summer surface temperatures in the desert are severe and a vehicle left in the sun is an oven. The marking target Ex ib IIC T4 and the rugged build are specified with that in mind, and the temperature class on the certificate is what an instrumentation engineer checks against the area classification.
A crew visiting wellpads drives between them, so a handset is charged in the vehicle or the camp, not in the classified area. The 4,000 mAh battery is specified to last the shift, and four-constellation GNSS gives a coordinate where the desert has no landmark.
A shamal wind coats everything in fine dust within an hour. IP68 sealing keeps it out of ports and speaker grilles, and that is what decides whether the handset still works when the wind drops.
Unlike a refinery, onshore staff are scattered. Enrolling every handset in the operator's own management console lets telecoms push policy, restrict the camera and wipe a lost unit remotely, without anyone returning to a central office.
An operator visiting a wellpad records pressures, photographs a weeping gland and sends the position. The same device calls the control room when the signal allows, and stores the entry for later when it does not.
Contractors installing flowlines work to a permit issued that morning. A handset enrolled in the operator's console carries the permit, the site directory and the daily report, and can be locked to approved applications.
Tie-in and bypass work at a crude receiving station mixes permanent plant with temporary hot work boundaries. Photographs with a position on the record support the permit and the as-built checks.
First, national conformity: MoIAT's ECAS-Ex scheme builds on IECEx certification, and the radio inside the phone needs TDRA approval; all of these are in progress for the IS-04Z1 and none is issued. Second, ADNOC's supplier registration, pre-qualification and In-Country Value certificate, which scores local content and Emirati employment into evaluation and is the reason supply is being structured through a UAE-registered partner. We cannot describe ADNOC Onshore's internal technical review of handhelds, so ask their procurement and HSE teams what they require.
No. IECEx, ATEX and ECAS certification are all in progress and none is issued, and ADNOC's own vendor review follows the certificates. SAMS has no approval, order or relationship with ADNOC Onshore.
No. SAMS is preparing technical documentation and working towards supply through a UAE-registered, ICV-scored partner. That describes intent, not a current approval or contract.
The device and the management profile are the same everywhere, but each area has its own classification. The right check is the certificate scope against the zone, gas group and temperature class of each plant in turn.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for United Arab Emirates. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
