IECEx Mobile Phone in Santos Basin
Two new pre-salt platforms started in 2025 in the Santos Basin: the FPSO Almirante Tamandaré at the Búzios field and the FPSO Alexandre de Gusmão at the Mero field. Its FPSOs create Zone 1 areas on process decks and in storage and offloading areas. This page explains what to look for in an IECEx mobile phone for Santos Basin, and where the IS-04Z1 stands against that list today.

More about Santos Basin that matters for portable equipment
Santos Basin: industry on the ground
Petrobras reported pre-salt production of 2.45 million barrels of oil equivalent a day in 2025, about 82% of its total output, which shows how much of its production now comes from pre-salt fields.
Santos Basin: geography and layout
The Santos Basin spans about 352,000 km2, mostly offshore, around 300 km southeast of Santos, and borders the coasts of Rio de Janeiro, Sao Paulo, Parana and Santa Catarina states.
Santos Basin: projects and investment
Giant fields found since 2007 include Tupi (about 8 billion barrels), Jupiter (about 1.6 billion barrels and 17 trillion cubic feet of gas) and Libra, estimated at 8 to 12 billion recoverable barrels.
Santos Basin: infrastructure
Pre-salt reservoirs are ultra-deep carbonates, roughly 5,000 to 7,000 m total depth below a thick salt seal, which drives the high-pressure, high-temperature design of wells and topsides.
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 Santos Basin. Large floating units in the Santos Basin involve global contractors and shipowners. IECEx, with a certificate of conformity and schedule of conditions, is a familiar framework for them, alongside Brazil's Inmetro-accredited route. The IS-04Z1 IECEx certification is in progress.

- 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

Questions · Santos Basin
Frequently asked questions
Can we buy an IECEx mobile phone in Santos Basin 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 in Santos Basin 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.
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.
Which areas at Santos Basin would use it?
Likely candidates are platform process modules, wellhead areas, gas compression and export, offloading areas. 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.
What hazardous zones appear on pre-salt FPSOs?
Typically the turret and riser area, process and gas treatment decks, compression and CO2 handling areas, crude storage and offloading, and helideck fuel. Zones, gas groups and temperature classes are on the unit's classification drawings, so request them before choosing handheld devices.
How far offshore are the Santos Basin fields?
The basin lies roughly 300 km southeast of Santos and the best-known discoveries are far offshore in deep water, so crew changes are mainly by helicopter and supply is by vessel. Confirm carry-on rules for powered devices with the operator.
How do spares reach a pre-salt platform?
Pre-salt units are far offshore, so crews and equipment move by helicopter and supply vessel. Spares need planning in advance. Confirm approvals, documentation and delivery routes with the operator and its contractors before relying on offshore replacement.
