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 intrinsically safe 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.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

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.

BSEE is the lead federal agency for safety and environmental oversight on the Outer Continental Shelf.
Gulf sea-surface temperatures average about 28 degrees Celsius in summer and feed Atlantic hurricanes, so storm evacuation and shutdown planning is part of normal offshore operations.
Operators must submit decommissioning plans before removing platforms and carry out post-decommissioning surveys, so offshore work continues after production ends.
Most offshore drilling in the Gulf takes place in the western part and in the Bay of Campeche, where the continental shelf is wide and shallow.
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.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In US Gulf of Mexico offshore platforms and rigs. Rounds on a platform cover the drill floor, wellhead areas, production decks and utility and compression areas, often in tight spaces. A handheld designed for intrinsic safety lets crews record readings and photographs at the point of work, rather than carrying notes back to a safe area.
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.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
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.
