Petrobras: geography and layout
The Tupi, Jupiter and Sugar Loaf discoveries of 2007 and 2008 lie in the Santos Basin about 300 km off the coast of Rio de Janeiro, so offshore work depends on long sea and helicopter transfers.

Explosion-Proof Smartphone for Petrobras
Petrobras is a majority state-owned Brazilian integrated oil and gas company headquartered in Rio de Janeiro. Petrobras was created in 1953 with the slogan 'The Oil is Ours' and a legal monopoly, and that monopoly ended with Law 9.478 of 1997, which also created the national petroleum regulator ANP. If you are specifying an explosion proof smartphone for Petrobras, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

Supplier approval · Petrobras
How suppliers reach Petrobras
Suppliers register through the Petronect portal: identify the company, select supply families, submit documents and pass technical evaluation to receive a registration certificate (CRC). The Corporate Registry is open to foreign companies; the Simplified Registry is for Brazilian companies only. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.

More about Petrobras that matters for portable equipment
Petrobras: who works there
The company runs six business areas: refining, transport and marketing; exploration and production; distribution; gas and power; international; and biofuels, so a buyer must identify which area controls a given site.
Petrobras: infrastructure
The Cenpes research centre in Rio de Janeiro, opened in 1963, is among the world's largest centres dedicated to petroleum research, and headquarters offices sit in downtown Rio.
Petrobras: projects and investment
In 2023 the company announced the resumption of a new production line at the Abreu e Lima refinery in Ipojuca, Pernambuco, intended to refine heavy crude from the pre-salt region.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Petrobras. On FPSOs and platforms in the Campos and Santos basins, 'explosion-proof' loosely covers several concepts. Flameproof Ex d enclosures protect fixed equipment, while intrinsic safety limits the energy of a portable device. For a handheld used on a topsides deck, the IS-04Z1 is designed around intrinsic safety rather than a flameproof casing.

Specifying an explosion proof smartphone for Petrobras
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 · Petrobras
Frequently asked questions
Can Petrobras buy the IS-04Z1 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 explosion proof smartphone for Petrobras 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
How does Petrobras approve suppliers?
Suppliers register through the Petronect portal: identify the company, select supply families, submit documents and pass technical evaluation to receive a registration certificate (CRC). The Corporate Registry is open to foreign companies; the Simplified Registry is for Brazilian companies only.
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.
Are offshore Petrobras platforms different from refineries for phone selection?
Yes. Offshore platforms combine Zone 1 and Zone 2 areas with salt air, vibration and limited space, while refineries have larger plant areas and more fixed infrastructure. Check ingress protection, corrosion resistance and wireless coverage needs separately for each, and confirm area classification with the asset operator.
Does Petrobras still source equipment only from Brazilian suppliers?
The legal monopoly ended in 1997 and the market is open to competition, but large operators usually apply local-content and registration rules and run their own supplier approval. Confirm the current registration requirements and any local-content expectations directly with Petrobras procurement.
Can a foreign company register to supply Petrobras?
Petrobras suppliers register through the Petronect portal and pass technical evaluation to receive a registration certificate. The Corporate Registry is open to foreign companies, while the Simplified Registry is for Brazilian firms only. Confirm current steps with Petrobras. The IS-04Z1 has no certificate yet.
