Mexican offshore production is concentrated in the shallow waters of the Bay of Campeche, worked from Ciudad del Carmen and the Tabasco coast. This page is for the safety, instrumentation and telecoms teams who need an explosion proof mobile phone for Mexico's offshore and upstream sites and want to know what a platform, a jack-up rig or an onshore base actually asks of one. The IS-04Z1 is designed for Zone 1 and Zone 21 duty and is in certification ahead of the Q4 2026 launch. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.

Offshore Mexico is a heavy-oil business. The Cantarell and Ku-Maloob-Zaap fields produce heavy, sour crude, and newer developments such as Ayatsil add to the same marine region. Most of the work is done from fixed platform complexes linked by bridges and pipelines, with drilling and workover done from jack-up rigs and support from supply vessels. A platform is a compact classified area: the wellbay, separation and compression decks are Zone 1 or Zone 2 for gas, the accommodation module is a pressurised safe area, and the walk between them is a few minutes in the open air with wind and spray. That is the route a handset has to survive, several times a shift, for years.
A phone that works in a workshop trial can still fail the rotation. These are the points that matter once the helicopter has left.
Crews move by helicopter or crew boat, and anything that is not on the manifest does not arrive. Handsets are enrolled, charged and tested onshore, and a spare travels with each crew so that one failed unit does not leave a team without a camera or a means of calling the control room until the next transfer.
A deck in the Bay of Campeche is wet with spray and warm for most of the year. IP68 sealing, rugged build and a rugged build are designed for that, and the battery is specified to last a shift rather than a morning, which matters on a deck with few places to charge safely.
An operator, a drilling contractor, a well-test company and a catering firm may all be on one platform at once. MDM profiles let each company's handsets carry their own approved apps and no more, and a device can be wiped when a contractor demobilises.
Connectivity offshore comes from the platform network, often over satellite or microwave links, and is limited. Handsets that cache permits, drawings and checklists for offline use, and sync when Wi-Fi is available, fit that pattern better than ones that need a live connection to open a procedure.
Helicopter operators set their own rules on electronic devices in the cabin. Ask the aviation contractor what they require for a handset in flight mode, and treat the Ex certificate and the aircraft rule as two separate checks.
An operator logs pressures and temperatures, photographs a weeping flange and reports its position on a deck with several look-alike modules. The 50 MP camera and position fix go into the same report, from the same device, without carrying a camera in a pouch.
When a jack-up arrives on location its classified areas arrive with it. Crews carry enrolled handsets for the permit, the daily report and the contact list, and the operator can restrict them to the apps approved for that campaign.
At Ciudad del Carmen, base staff and vessel crews coordinate cargo and fuel transfers near classified storage. A handset that can be used at the fuel store and aboard the vessel avoids switching between devices on the quay.
The method is the same, but the layout differs. On a platform, classified zones are tight and close to living quarters, so the drawing and the ventilation arrangements decide where a handset may go. The IS-04Z1 design target is Zone 1 and Zone 21, with certification in progress.
Sour gas is a toxic hazard as much as a flammable one, and personal gas detectors remain the safety device for it. A phone is not a gas detector. Ask the operator's safety team how detectors and handsets are meant to be carried together.
Each operator does, through its own procurement and HSE process. Licence conditions and Mexican regulation, including ASEA in the hydrocarbons sector, sit above that, so ask each operator what evidence their review needs.
Not before a certificate covers it. Documentation can be reviewed now, and an evaluation can start in a safe area once units are available; we will not supply an uncertified device into a classified zone.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Mexico. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
