Great Yarmouth
The port, owned by Peel Ports since 2015, services the southern North Sea oil and gas sector and has an offshore energy operations and maintenance campus funded by Norfolk County Council.
Great Yarmouth, the main energy port for the area, lies 20 miles east of Norwich, reached by the A47 and by the Wherry Lines railway from Norwich station to its terminus there. Nearby hazardous-area work centres on the Bacton gas terminal complex on the north Norfolk coast, which receives North Sea gas, and the offshore energy port at Great Yarmouth. A hazardous area smartphone distributor in Norwich and the Norfolk coast would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Norwich and the Norfolk coast has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
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.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Norwich. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
The port, owned by Peel Ports since 2015, services the southern North Sea oil and gas sector and has an offshore energy operations and maintenance campus funded by Norfolk County Council.
Bacton is a complex of six gas terminals operated by Shell, Eni, Perenco and National Grid, plus the Interconnector and BBL terminals linking to continental Europe.
Norwich Airport is home to major offshore energy helicopter transport operations alongside corporate and general aviation and the East Anglian Air Ambulance, and KLM Engineering runs six maintenance bays across three hangars there.
The Norwich City Council area had an estimated population of about 144,000, so engineers and technicians are drawn from a sizeable local labour pool as well as from the wider county.
North Sea oil from the 1960s supported an oil rig industry at Great Yarmouth that services offshore natural gas rigs, and more recently offshore wind and other renewable energy industries have followed.
The Scroby Sands Wind Farm, with thirty turbines, is visible from the Great Yarmouth seafront, a reminder that offshore wind operations and maintenance are run from the Norfolk coast.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Norwich and the Norfolk coast. Norwich itself has no classified-area sites. The hazardous areas are on the north Norfolk coast at Bacton, a complex of six gas terminals plus the Interconnector and BBL terminals, with gas process, receipt and blending areas. The terminal operators classify them. Great Yarmouth port facilities add offshore support areas, which may or may not be classified.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Norwich and the Norfolk coast. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
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.
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.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
Likely candidates are gas terminal process areas, gas receipt and blending, interconnector terminals, offshore support port facilities. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Norwich and the Norfolk coast.
The Norfolk coast is relatively dry by UK standards but exposed to wind and salt air, which can corrode connectors and fixings. For offshore wind and port work, look for good ingress protection and corrosion resistance, and ask the site about its own requirements.
Norwich is mainly a service, research and distribution city, so most classified areas lie on the coast, around the energy port at Great Yarmouth, gas terminals and offshore wind and gas support bases, as well as in fuel depots and food or feed plants. Confirm the site classification with each operator.
Bacton is a complex of six gas terminals run by Shell, Eni, Perenco and National Grid, plus the Interconnector and BBL terminals. Equipment for terminal areas is normally approved by each terminal operator, so approvals may differ between neighbouring sites. Ask each operator for its own requirements.
