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 · 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 Port Harcourt. Operators and contractors keep their own approved-vendor processes, and crews often travel by road or boat between sites. EMM and MDM support allows one administrator to manage devices across them. Charge in safe areas such as offices or camps, and plan around patchy connectivity at creek sites.

Questions · Port Harcourt
Frequently asked questions
Can we buy an industrial 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 industrial smartphone in Port Harcourt cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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 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.
