Thames Oilport
The former Coryton refinery, which stopped refining in 2012 after Petroplus collapsed, became a fuel import terminal. Greenergy holds two thirds and Shell one third after Greenergy bought Vopak's share.

ATEX and IECEx Mobile Phone in London
London has no refinery, but Thames-side fuel terminals supply the capital: Thames Oilport on the former Coryton refinery site and the large West Thurrock terminal in Essex. Gas network and utility sites add smaller classified areas. If you are specifying an ATEX and IECEx mobile phone for London and the Thames, this page covers the markings, the approvals and the current certification status of the IS-04Z1.

More about London and the Thames that matters for portable equipment
London and the Thames: background
London is Europe's largest city economy and one of the world's major financial centres, so many suppliers, consultancies and head offices that approve equipment are based there.
London and the Thames: geography and layout
London stands on the River Thames at the head of a 50 mile tidal estuary down to the North Sea, with 9.14 million residents in 2025 and a metropolitan area of 15.4 million.
London and the Thames: background
The Port of London expanded downstream in the 18th and 19th centuries, and the Underground, the world's first urban rail network, was created to ease traffic congestion.
London and the Thames: people and language
London's diverse communities speak over 300 languages, so site teams are multilingual, though safety documentation is usually in English.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In London and the Thames. A reviewer for a Thames-side terminal would expect certificate evidence aligned with the operator's DSEAR assessment. The terminals are owned by groups such as Greenergy, Shell and Navigator Terminals, with international contractors visiting for maintenance, so a dual ATEX and IECEx route is designed to ease paperwork. Both are in progress for SAMS and none is issued.

Questions · London
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in London 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 ATEX and IECEx mobile phone in London 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.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Which areas at London and the Thames would use it?
Likely candidates are fuel storage terminals, marine jetties, road tanker loading, gas network sites. 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.
Does London's weather matter for handheld devices?
A temperate oceanic climate means mild temperatures but frequent light rain, on about 110 days a year. Typically devices used outdoors need good water ingress protection and users check ratings against site conditions, especially on the tidal Thames.
How should I plan equipment deliveries to London?
Deliveries typically arrive by road or air, and the congested metropolitan area calls for scheduled slots and extra time. Confirm customs treatment for imported electronics and any site access or gate checks with the client.
Why does travel matter for terminal work near London?
The terminals are in Essex, so crews and equipment normally travel by road from the capital, and site access follows each operator's induction and permit rules. Plan time for sign-in, safe-area handover and device checks. Confirm the current access arrangements with the terminal operator.
