United Kingdom: industry on the ground
UK crude oil and condensate production had fallen to about 630,000 barrels a day by 2024, so much of the current work is maintenance, life extension and decommissioning of mature installations.

More about United Kingdom that matters for portable equipment
United Kingdom: industry on the ground
About 98 per cent of UK oil and gas production comes from offshore fields, and the services industry in Aberdeen has been a leader in offshore technology.
United Kingdom: rules and approvals
The Dangerous Substances and Explosive Atmospheres Regulations 2002 require employers to identify and classify areas where explosive atmospheres may occur and to avoid ignition sources from unprotected equipment in them.
United Kingdom: rules and approvals
Since 1 October 2024 CE marking has been recognised in Great Britain without an end date, so ATEX-certified products can be sold there without UKCA, while Northern Ireland still requires CE.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
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 United Kingdom. Intrinsic safety suits the long shifts on a platform or terminal and the lone-worker visits to rural gas sites. A handheld that limits ignition energy lets a worker take photographs sharp enough for permit or inspection evidence, avoiding a second trip into the zone, and keep a position and connection.

- 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

Questions · United Kingdom
Frequently asked questions
Can we buy an intrinsically safe mobile phone in United Kingdom today?
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.
What does an intrinsically safe mobile phone in United Kingdom cost?
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.
What does ‘intrinsically safe’ mean for the IS-04Z1?
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.
Which sites in United Kingdom does this cover?
The market guide for United Kingdom covers Aberdeen, St Fergus, Sullom Voe, Grangemouth, among others. Site-level pages are linked below.
How will SAMS supply United Kingdom?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
What does DSEAR mean for choosing a phone for UK plants?
DSEAR places duties on employers to classify areas where explosive atmospheres may occur and to avoid ignition sources from unprotected equipment. A site will therefore expect devices used in classified areas to be suitable for the zone, gas group and temperature class stated in its area classification records.
Is CE-marked ATEX equipment accepted in Great Britain?
Yes. Since 1 October 2024 CE marking has been recognised in Great Britain without an end date, so an ATEX-certified product can be sold there without UKCA, although a UKCA route with a UK approved body also exists. Northern Ireland still requires CE. Check the current rules before shipping.
How does the IS-04Z1 cope with patchy coverage on a UK platform or rural site?
It combines 4G LTE, Wi-Fi and four-constellation GNSS to hold a position and a connection where one network is not enough. Actual coverage depends on the site, so test the unit on your own route before relying on it.
