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.

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.

The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Petrobras. Pre-salt development brings international operators, shipyards and EPCs to Brazil, and many of them already use IECEx documentation. A certificate of conformity with its schedule of conditions gives Petrobras reviewers and these visiting contractors one shared document. The IS-04Z1 is designed towards IECEx, which is still in progress.

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 IECEx mobile phone for Petrobras 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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
