Port Harcourt: logistics and access
Onne, in Eleme, hosts the Onne Oil and Gas Free Zone, a main offshore support base where supply vessels call every week and where Shell and other operators lease berths and shore facilities.
Port Harcourt: infrastructure
The Port Harcourt Refining Company at Alesa Eleme runs two refineries, a 1965 plant of 60,000 barrels per stream day and a 1989 plant of 150,000, giving 210,000 barrels per stream day combined.
Port Harcourt: background
Shell-BP found oil at Oloibiri in 1956 and discovered the Afam and Bomu wells in Ogoni territory in the same period, so the region around Port Harcourt has among Nigeria's oldest producing areas.
Port Harcourt: background
Port Harcourt was founded in 1912 to export coal from Enugu, 243 km to the north, over the Eastern Line railway, so it was a port city long before oil.
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 Port Harcourt. Many operators keep offices in Port Harcourt, so reviewers there see contractor packs from a wide range of firms, including international EPCs. ATEX and IECEx evidence together give them a familiar basis for assessing a handheld at flow stations and gas plants. The IS-04Z1 has no certificate yet, as certification is in progress.

Specifying an ATEX and IECEx mobile phone for Port Harcourt

- 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

Questions · Port Harcourt
Frequently asked questions
Can we buy an ATEX and IECEx mobile phone in Port Harcourt 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 ATEX and IECEx mobile phone in Port Harcourt 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 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 Port Harcourt would use it?
Likely candidates are refinery process units, flow stations and gas plants, export and port facilities, pipeline and pumping facilities. 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.
How should I arrange logistics to Port Harcourt?
Equipment commonly arrives through the Lagos ports or airport and then moves by road or air, or through the Port Harcourt area port facilities, depending on the shipment. Allow time for clearance and security arrangements, and agree site access and device registration with the operator beforehand.
Why is Port Harcourt important for hazardous-area work in Nigeria?
It is a base for the Niger Delta oil industry: the first shipment of Nigerian crude left through the port in 1958 and operators such as Shell, Chevron and Agip have offices there. Wellsites, flow stations and terminals are around the city, so confirm each site's rules.
How do I reach creek and swamp sites with equipment?
Many facilities are in low-lying creek and swamp areas reached by road or boat. Plan transport with the operator or contractor, protect devices from rain and spray, and keep spare units charged in a safe area. Confirm access rules with the site operator.
