Rugged Smartphone in Santos Basin
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. Its FPSOs create Zone 1 areas on process decks and in storage and offloading areas. This page explains what to look for in a rugged smartphone for Santos Basin, and where the IS-04Z1 stands against that list today.

More about Santos Basin that matters for portable equipment
Santos Basin: geography and layout
The basin is known for thick salt layers that deform into structures in the subsurface, and the pre-salt Tupi reservoir sits in microbialite carbonates of the Guaratiba Group beneath that salt.
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: projects and investment
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.
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.
The term · rugged
What “rugged” means for a smartphone
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Santos Basin. Offshore in the South Atlantic, salt, spray and heat challenge any electronics. IP68 resists water and dust ingress, which helps on open decks. It is not an explosion-protection rating, and it does not replace the Ex marking operators check.

Specifying a rugged smartphone for Santos Basin
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 · Santos Basin
Frequently asked questions
Can we buy a rugged smartphone in Santos Basin today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does a rugged smartphone 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.
How rugged is the IS-04Z1?
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.
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.
