St Fergus
The terminal handles roughly a quarter of Britain's gas and sends natural gas liquids to Mossmorran. It is owned by North Sea Midstream Partners, with Shell, Esso and others as tenants.

IECEx Mobile Phone in Scotland
In 2022 oil and gas extraction contributed an estimated 25.2 billion pounds of gross value added, about 11.8% of Scottish GDP, which keeps offshore and terminal work a major source of hazardous-area activity. Several of these sites are in transition. If you are specifying an IECEx mobile phone for Scotland, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

What Scotland means for portable equipment
Grangemouth
The refinery stopped processing crude in 2025 and is becoming a fuels import terminal, while the adjacent INEOS complex continues to run the UK's last operating ethylene cracker.
Field notes · Scotland
More about Scotland that matters for portable equipment
Scotland: background
Grangemouth Refinery on the Firth of Forth began operating in 1924 and was the only crude oil refinery in Scotland, but it has now closed; its neighbouring petrochemical complex dates from 1951.
Scotland: geography and layout
Of about 25,000 jobs directly dependent on offshore oil and gas in 2019, 98% were in Aberdeen and Aberdeenshire, so equipment demand and contractor skills cluster in the north-east.
Scotland: industry on the ground
Scottish waters hold the largest oil resources in Western Europe; oil was discovered in the North Sea in 1966 and the first year of full production was 1976.
Scotland: projects and investment
Hydrocarbon production is expected to fall to about a third of 2019 levels by 2035, and a global decommissioning market of around 67 billion pounds over ten years is forecast, so abandonment work is growing.
The term · IECEx
What “IECEx” means for a smartphone
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Scotland. Scotland's large process and gas sites attract international EPCs, turnaround specialists and, at Mossmorran, decommissioning contractors who may arrive with IECEx documentation. The aim is a certificate of conformity and a schedule of conditions that an engineer can read against a specific area. At present it is still in progress.

Specifying an IECEx mobile phone for Scotland
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Scotland
Frequently asked questions
Can we buy an IECEx mobile phone in Scotland today?
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
What does an IECEx mobile phone in Scotland cost?
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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
Which areas at Scotland would use it?
Likely candidates are petrochemical process units, natural gas liquids plant, gas terminals, fuel import and storage terminal. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Is intrinsically safe the same as explosion proof?
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.
Which marking should Ex phones carry for UK offshore work?
Offshore installations in the UK sector normally expect equipment certified for explosive atmospheres under UK rules, and CE-marked ATEX equipment has been widely accepted under transitional arrangements. Operators also add their own policies, so confirm the accepted marking and any site-specific approvals with the duty holder.
Is decommissioning work a growing user of Ex equipment in Scotland?
Decommissioning of ageing North Sea installations is forecast to grow as production declines, and it involves cleaning, cutting and removal of hydrocarbon systems in classified areas. Teams often need portable communications that are certified for the area, so confirm requirements with the operator or decommissioning contractor.
Which Scottish sites are the main hazardous-area locations?
The Grangemouth petrochemical complex on the Firth of Forth, Mossmorran in Fife and the St Fergus gas terminal in Aberdeenshire. Several are in transition, so activity may be shifting. Confirm current requirements with the site operator before planning equipment.
