OMV Petrom runs the Petrobrazi refinery in Prahova county, a spread of onshore oil and gas assets across the country and, with Romgaz, the Neptun Deep gas development in the Black Sea. This page is for the HSE, instrumentation and telecoms people who need an explosion proof mobile phone in Romania that can be carried from a refinery unit to a well site without a change of device. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · certification programme in progress
OMV Petrom’s own reporting describes the Petrobrazi refinery, in Prahova county near Ploiești, as a 4.5 million tonne a year plant able to process the company’s Romanian equity crude. Hydrocarbon vapour from crude, naphtha and gasoline is the everyday Zone 1 and Zone 2 situation there, with hydrogen in the reforming and hydrotreating units adding the IIC gas group. Upstream, the company reports its domestic production through seven assets: Moesia, Crișana, Oltenia, Muntenia, Muntenia Vest, Moldova and Petromar, the offshore asset. That means wellheads, tank batteries, separators and gas treatment spread across much of the country rather than one fence. On top of both sits Neptun Deep, developed with Romgaz: an offshore production platform in the deep-water Pelican South and Domino area, subsea wells, a subsea pipeline of about 160 km to the shore at Tuzla and a gas measurement station there, with first gas targeted for 2027. The handset question is therefore three questions: an oil refinery, a dispersed field and a new offshore system.
The same company asks one device to work in three settings. These are the points an engineer from each setting would raise first.
A refinery overhaul at a site of Petrobrazi’s size puts a large contractor population inside the fence for a few concentrated weeks. Android Enterprise enrolment lets a pool of handsets be issued at the gate, limited to the permit, messaging and photograph applications the site allows, and wiped when the crew demobilises.
Refinery hydrogen is the reason the gas group on a certificate matters. The marking target for the IS-04Z1 is II 2 G Ex ib IIC T4, and the gas group and temperature class are what the explosion protection document is checked against, not the word Zone 1 on its own.
A field operator may visit a handful of well sites alone in a day. Four-constellation GNSS, 4G LTE and Wi-Fi give a position and a link at each, and a 4,000 mAh battery is sized to cover the round without a charging point inside the classified area.
Black Sea platforms and the Tuzla landfall are exposed to wind, spray and condensation. IP68 sealing is aimed at that, and any offshore use would be subject to the operator’s own assurance process and the platform’s own classification.
Inspection photographs are useful at a refinery and unwelcome at a platform control room. A camera policy pushed from the management console, rather than a camera-free phone, lets the site set the rule per zone.
An operator on a distillation or hydrotreating unit records a reading, photographs a leaking flange and raises a work request from the same device, instead of carrying a radio, a camera and a paper round sheet into the classified area.
A maintenance crew sent to a flowline fault in Oltenia or Muntenia needs a position, a photograph and a line back to the planner. One handset managed from the existing console keeps all three together.
Commissioning brings many specialist contractors onto a new system. A common enrolled handset lets them share one permit and punch-list application without carrying personal phones near the classified deck.
We have no visibility of the company’s internal process and will not invent one. Ask the site’s procurement and HSE teams what a supplier file must contain: typically the certificate, the declaration of conformity, the safe-use instructions and the evidence behind the zone, gas group and temperature class the unit will meet.
It is designed for Zone 1 and Zone 21 with a IIC marking target, so one device covers both settings. Whether it may be used in a given area still depends on the classification of that area and on the final certificate.
Offshore is one of the design cases, subject to the operator’s own assurance and to the certificate that exists at the time. Nothing will be supplied into a classified area before that certificate is issued.
No. SAMS has no supply agreement, pilot or relationship with OMV Petrom. The page describes what the operator’s teams would ask for and what the device is designed for.
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 Romania. 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.
