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.

Industrial 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 industrial 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 · industrial
What “industrial” means for a smartphone
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In London and the Thames. Terminal fleets involve operator staff, hauliers and visiting contractors, so MDM or EMM enrolment and clear role-based apps are important. Because the terminals are in Essex, crews travel out from the capital, and devices must be signed in and out reliably. Charging should take place in offices or control rooms, away from tank areas.

Specifying an industrial mobile phone for London
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.

- 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

Questions · London
Frequently asked questions
Can we buy an industrial mobile phone in London today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an industrial mobile phone in London 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.
Is the IS-04Z1 an industrial phone as well as an Ex phone?
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
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.
