More about Port Harcourt that matters for portable equipment
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.
Port Harcourt: who works there
Oil companies with offices in Port Harcourt include Shell, Chevron and Agip, so contractors and suppliers often deal with international operator procedures in the city.
The term · IECEx
What “IECEx” means for a smartphone
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 Port Harcourt. With seaports at Onne and the city wharf plus flow stations and pipelines, Port Harcourt draws visiting international contractors who work from IECEx paperwork. The scheme supplies a certificate of conformity and a schedule of conditions that spell out limits. IS-04Z1 IECEx certification is in progress, so no certificate can be shown.

Questions · Port Harcourt
Frequently asked questions
Can we buy an IECEx smartphone in Port Harcourt today?
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.
What does an IECEx smartphone 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.
Does the IS-04Z1 hold an IECEx certificate?
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
