Marine climate
Salt air, heat and humidity are routine, so enclosure ratings and corrosion resistance matter.
The P-50 platform began production in April 2006 in the Albacora-Leste field of the Campos Basin, a milestone that made Brazil self-sufficient in oil production. 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. This page explains what to look for in an IECEx smartphone for Brazilian offshore oil platforms, and where the IS-04Z1 stands against that list today.
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.

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.
The companies on site and the hazardous-area types a handset is likely to meet there.
Salt air, heat and humidity are routine, so enclosure ratings and corrosion resistance matter.
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.
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.
Petrobras was created in 1953 with a legal monopoly, and a 1997 law ended that monopoly and set up the national petroleum agency ANP as the regulator and supervisor of the industry.
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 Brazilian offshore oil platforms. FPSOs often involve crews and equipment from several countries, so the IECEx scheme and its certificate of conformity with schedule of conditions are familiar to many visiting contractors. For Brazil, Inmetro-accredited routes also apply. The IS-04Z1 IECEx route remains in progress.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
