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.
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. 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. This page explains what to look for in an IECEx smartphone for Norwich and the Norfolk coast, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Norwich and the Norfolk coast: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. 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.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
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.
Regional industry bodies have described the offshore wind supply chain in East Anglia as a growing cluster, with ScottishPower Renewables and Vattenfall wind farms off the coast driving demand for coastal contractors.
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.
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 Norwich and the Norfolk coast. The Interconnector and BBL terminals at Bacton connect the UK gas system to continental Europe, so visiting engineers may expect IECEx-based paperwork. The aim is a certificate of conformity and a schedule of conditions that a terminal engineer can review against a given area. At present that paperwork is still in progress.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
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.
In Great Britain, equipment for explosive atmospheres is normally supplied under UK regulations with UKCA marking, and CE-marked ATEX equipment has been widely accepted under transitional rules. Check the current position with the site operator and certification body before ordering handheld devices.
Great Yarmouth is about 20 miles east, so road transfers of equipment and engineers are short, but offshore access depends on vessel and helicopter schedules and weather. Plan equipment delivery and testing onshore at the port base ahead of crew changes, and confirm timings with the operator.
No. It is a cathedral city and service centre for East Anglia. Nearby hazardous-area work centres on the Bacton gas terminal complex on the north Norfolk coast and the offshore energy port at Great Yarmouth. Confirm requirements with the site operator for the specific terminal.
