FPSO-based fleet
New pre-salt units such as FPSO Almirante Tamandare (Buzios) and FPSO Alexandre de Gusmao (Mero) started up in 2025; FPSOs carry a full process plant on deck.
This is a regional grouping of offshore production platforms and FPSOs in Brazilian waters, mainly in the Campos and Santos basins. Pre-salt fields supplied 82 per cent of Petrobras production in 2025, so gas-hazard zones exist on process decks and in storage and offloading areas. If you are specifying an industrial mobile phone for Brazilian offshore oil platforms, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Brazilian offshore oil platforms: 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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP rating for dust and water | IP68 design |
| Fleet management | EMM and MDM support | Android 16 with EMM and MDM |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Brazilian offshore oil platforms: Oil and gas process modules, Wellhead areas, Gas compression | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Brazil Oil Platforms. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

Equipment and crews move by supply vessel and helicopter, so spares and replacements need planning.
Petrobras describes itself as producing about 2.99 million barrels of oil equivalent a day in 2025, and Brazil accounted for roughly 92 percent of its worldwide production in 2014.
Under an ANP decision Petrobras operates several subsalt blocks and keeps a minimum 30 percent equity share in future licences, so most platform work still flows through Petrobras contractor procedures.
In 2000 Petrobras set a world record for deepwater exploration at 1,877 metres below sea level, and Brazilian offshore units have since moved into progressively deeper water.
Petrobras reported that 62.7 percent of its Brazilian proved developed reserves in 2014 were in the offshore Campos Basin, which explains the large fleet of platforms off Rio de Janeiro state.
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Brazilian offshore oil platforms. Offshore fleets run on supply vessel and helicopter logistics, so replacement devices cannot be delivered quickly. EMM or MDM enrolment before mobilisation lets onshore teams push settings to Android 16 handsets. Charging belongs in safe accommodation or control areas, and spares should be planned.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
Likely candidates are oil and gas process modules, wellhead areas, gas compression, cargo tanks and offloading areas. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
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.
Local content has been a factor in Petrobras projects; the P-56 topside, for example, reached 72.9 percent domestic content. Handheld equipment is a small part of that, but confirm with the contractor whether any local-content or Brazilian certification requirement applies to your supply.
Typically two layers: conformity assessment for Ex certification (commonly through Inmetro-recognised bodies) and Anatel homologation for radio equipment. Requirements change, so confirm current rules with the operator and a local certification adviser before shipping to a platform.
Equipment and crews move by supply vessel and helicopter, so spares and replacements need planning. Operators control access and often check or prepare devices onshore first. Confirm approvals, documentation and delivery routes with the operator and its contractors.
