WhereCNOOC
Short answer. An explosion proof smartphone for CNOOC cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Supplier approval · CNOOC
How suppliers reach CNOOC
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.

CNOOC: projects and investment
A floating wind demonstrator near the Wenchang oil fields, 136 km from shore in water 120 m deep, fed power into the grid in 2023 with 7.25 MW installed capacity.
CNOOC: geography and layout
The group's headquarters are in Beijing, in a building that opened in 2006, while production is offshore, notably in Bohai Bay and the South China Sea, far from head office.
CNOOC: who works there
CNOOC holds 7.34% of the deepwater Buzios field and 9.65% of the Mero development in Brazil, so some of its staff and contractors also work under overseas operators' rules.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In CNOOC. On offshore platforms and FPSOs in the Bohai Sea and South China Sea, 'explosion-proof' loosely covers several concepts. Flameproof Ex d protects fixed equipment, while intrinsic safety limits the energy of a handheld. A phone on a platform deck is portable, so the IS-04Z1 is designed around intrinsic safety.
The route · supply
Sourcing the IS-04Z1 for CNOOC
There is no stock to order for CNOOC yet. The IS-04Z1 is pre-launch, certification is in progress, and supply will run through authorised distributors after the certificates are issued. Procurement teams can prepare now with the datasheet, the certification schedule and a safe-area evaluation.
- 01
Request the datasheet
The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
- 04
Register for launch
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
Questions · CNOOC
Frequently asked questions
Can CNOOC buy the IS-04Z1 today?
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.
What does an explosion proof smartphone for CNOOC cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still in progress.
How does CNOOC approve suppliers?
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams.
How will SAMS supply CNOOC?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
What language is needed for documentation in China?
Chinese is the working language at Chinese sites, so labelling, manuals and training for hazardous-area devices are normally expected in Chinese, with English accepted for some engineering exchange. Confirm the required documentation language with CNOOC's procurement and safety departments.
How do typhoons and sea conditions affect offshore equipment planning?
Offshore facilities in the South China Sea and Bohai Bay area typically plan around seasonal storms and cold-weather periods, which restrict crew changes and logistics. For handheld devices this means robust sealing and battery planning; confirm operating rules with the platform operator.
What should be checked for typhoon-season offshore use?
Check ingress protection, battery behaviour in heat and humidity, and whether the platform's rules allow handheld devices in a given area. IP68 helps with rain and spray but is not explosion protection. The IS-04Z1 is not yet certified. Confirm conditions with the platform operator.
