Platforms
BP operates Thunder Horse, a semi-submersible in about 1,840 m of water with first oil in 2008. Shell operates Perdido, a spar in about 2,450 m of water, with Chevron and BP as partners.
The US Gulf of Mexico, which US agencies now call the Gulf of America, is a mature offshore region with deepwater platforms working off Louisiana and Texas. Hazardous-area work covers well bays, process decks and drill floors, regulated offshore by the Bureau of Safety and Environmental Enforcement. If you are specifying an ATEX and IECEx smartphone for US Gulf of Mexico offshore platforms and rigs, 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 US Gulf of Mexico offshore platforms and rigs: 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.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Marking | II 2 G Ex ib IIC T4 on the rating plate | Design target; not yet marked |
| EU-type examination certificate | Notified body number and certificate ID | In progress with TÜV; not issued |
| IECEx certificate of conformity | Number listed on the IECEx online register | In progress; not issued |
| Where it applies | US Gulf of Mexico offshore platforms and rigs: Drill floors and well bays, Production process decks, Wellhead areas | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Gulf of Mexico Rigs. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
BP operates Thunder Horse, a semi-submersible in about 1,840 m of water with first oil in 2008. Shell operates Perdido, a spar in about 2,450 m of water, with Chevron and BP as partners.
BSEE is the lead federal agency for safety and environmental oversight on the Outer Continental Shelf.
About 27,000 abandoned oil and gas wells lie beneath the Gulf, so well plugging and decommissioning is a continuing source of offshore work alongside production.
The Gulf is one of the largest offshore petroleum regions in the world and accounts for about 14 percent of United States crude oil production, according to the encyclopaedia entry on the Gulf.
The US Bureau of Safety and Environmental Enforcement is the federal agency responsible for offshore safety and environmental protection and sets decommissioning requirements, including plans for removing platforms and plugging wells.
By 1975 around 400 rigs in the Gulf hosted a temporary population of more than 10,000 workers, rotated on staggered weekly schedules, and automation has since reduced the offshore headcount.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In US Gulf of Mexico offshore platforms and rigs. Offshore reviewers in the US Gulf typically look to the operator's safety case and BSEE oversight, with NEC or Zone-based evidence. BP, Shell, Chevron and ExxonMobil also employ international contractors who may carry ATEX or IECEx documents, which a dual route is designed to serve. Both are in progress for SAMS and none is issued.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are drill floors and well bays, production process decks, wellhead areas, utility and compression 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.
Offshore trips run for days at a time with crews rotating on set schedules, and charging points in classified areas are limited. Plan for a full-shift battery, spare cells approved for the area, and charging only in safe areas as the platform rules require.
Decommissioning is a steady activity, with tens of thousands of old wells to plug and structures to remove under regulator-approved plans. Contractors on these jobs still work in areas that may contain hydrocarbons, so the same area-classification checks apply.
Facilities lie well offshore, with Thunder Horse about 150 miles south-east of New Orleans, so access depends on helicopter and vessel schedules. Plan device enrolment, battery charging and safe-area handover onshore, and ask the operator how equipment is checked and approved before it travels.
