Sonangol: infrastructure
A 200,000 barrel-a-day refinery at Lobito, with Sonangol planned to hold 70%, has been proposed but much delayed, so check current project status before assuming new refinery work.

IECEx Mobile Phone for Sonangol
Economic growth in 2025 was reported to have eased partly because of scheduled inspections and maintenance shutdowns in the oil sector, showing that planned shutdown periods affect activity. Since the National Oil, Gas and Biofuel Agency (ANPG) took over regulatory functions in 2019, Sonangol operates as a commercial company with upstream, midstream and downstream activities, including the 65,000 barrel-per-day Luanda refinery. This page explains what to look for in an IECEx mobile phone for Sonangol, and where the IS-04Z1 stands against that list today.

Supplier approval · Sonangol
Becoming an approved supplier to Sonangol
Sonangol runs a Supplier Portal (Portal de Fornecedores) for registration, pre-qualification and qualification; pre-registration is completed through the suppliers section of its website and is free. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.

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 Sonangol. Offshore Angola attracts international operators, service companies and EPCs, many of which already use equipment assessed under the IECEx scheme. A certificate of conformity with its schedule of conditions gives a Sonangol team and a visiting contractor the same document to review. The IS-04Z1 is being taken towards IECEx, but no certificate exists yet.

Questions · Sonangol
Frequently asked questions
Can Sonangol buy the IS-04Z1 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 IECEx mobile phone for Sonangol 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.
How does Sonangol approve suppliers?
Sonangol runs a Supplier Portal (Portal de Fornecedores) for registration, pre-qualification and qualification; pre-registration is completed through the suppliers section of its website and is free.
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.
Is Sonangol the operator at Angola's offshore fields?
Usually not directly. Sonangol acts as concessionaire and partner, while international oil companies commonly operate the offshore blocks. Equipment standards and approved-vendor processes therefore depend on the operator of the specific field. Identify the operator and ask for its contractor and equipment requirements.
What language should documentation be in for Angola?
Portuguese is the official language, so manuals, labels and training for hazardous-area devices are often expected in Portuguese, while international operators commonly work in English. Confirm with the operator and Sonangol which language is required for approval and for site induction.
Can a phone be supplied to Sonangol sites directly?
Not at present. Sonangol uses a Supplier Portal for registration and qualification, and SAMS expects supply after certification to come through authorised distributors. SAMS can currently share a datasheet and schedule. Check the portal's current requirements before assuming any route is open.
