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

IECEx Mobile Phone in Campos Basin
Roncador ranked first among the top fields of the Santos, Campos and Espirito Santo basins in 2010 at 129.7 million barrels of oil equivalent, and the Campos Basin had eight discoveries in 2011. 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 an IECEx mobile phone for Campos Basin, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

More about Campos Basin that matters for portable equipment
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.
Campos Basin: projects and investment
A 65 million barrel discovery was announced by Petrobras near the Barracuda field in February 2010, showing continued exploration activity in this mature basin.
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 Campos Basin. With 39 platforms in operation in December 2025, 18 of them FPSOs, the basin sees many service companies and visiting specialists. IECEx certificates of conformity with schedules of conditions are familiar to such teams. The IS-04Z1 IECEx certification is in progress.

Specifying an IECEx mobile phone 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 an IECEx mobile phone in Campos 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 an IECEx mobile phone 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.
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 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.
