Offshore climate
Salt, humidity and heat are normal, so equipment is commonly checked onshore before it goes offshore.

Rugged Smartphone in Campos Basin
Production comes from varied reservoir types, including turbidite sandstones, fractured basalts, coquinas and limestones, which leads to a mix of facility designs and well services across the basin. In December 2025 it had 39 platforms in operation, 18 of them FPSOs, creating Zone 1 areas on process decks and in storage and offloading areas. If you are specifying a rugged smartphone for Campos Basin, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

WhereCampos Basin
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Campos Basin: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

What Campos Basin means for portable equipment
Mature basin
The basin produced 828,600 barrels of oil equivalent a day in 2025, well below its 2011 peak, with many older units needing regular maintenance.

More about Campos Basin that matters for portable equipment
Campos Basin: who works there
In 2014 about 62.7 percent of Petrobras' Brazilian proved developed reserves were in the Campos Basin, and the company set its basin headquarters in Macae in the 1970s.
Campos Basin: background
Offshore exploration began in 1968 and the first well was drilled in 1971; the Garoupa field was found in 1974 and the first production came from Enchova in 1977 at 124 m of water.
Campos Basin: geography and layout
The Campos Basin covers about 115,000 km2, almost all of it offshore, with only about 500 km2 onshore near Rio de Janeiro, and is one of 12 coastal sedimentary basins in Brazil.
Campos Basin: projects and investment
By 2003 some 41 oil and gas fields had been discovered 50 to 140 km from the coast in water 80 to 2,400 m deep, and the basin was producing about 1.21 million barrels per day.
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 Campos Basin. Salt, humidity and heat are normal offshore, which is why equipment is commonly checked onshore before going out. IP68 helps with spray and dust, but it is a different matter from explosion protection. Corrosion on contacts and seals should be inspected during the onshore check.

Specifying a rugged smartphone for Campos 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 · Campos Basin
Frequently asked questions
Can we buy a rugged smartphone in Campos 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 a rugged smartphone in Campos Basin 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.
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 Campos Basin would use it?
Likely candidates are platform process modules, wellhead areas, crude storage and offloading, gas compression. 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.
Do older and newer platforms in the Campos Basin differ for device approval?
Not necessarily, but the operator differs. Some shallow fields passed to Trident Energy in 2020 while Petrobras runs many others, so induction rules and approved-device lists can vary. Confirm with each operator's safety team which markings and approvals they accept.
What hazardous areas appear on Campos Basin production units?
Typically wellheads, separation and gas treatment, compression, crude storage and offloading, and the helideck fuel area. Classification drawings from the unit operator give the exact zones, gas groups and temperature classes, so request them before choosing a handheld device.
Are older platforms a particular concern for device selection?
The basin is mature, and many older units need regular maintenance, so rounds are frequent. That favours a rugged, intrinsically safe handheld, but each platform has its own classification. Ask the operator for it rather than assuming that one marking suits every unit.
