Oil & gas EDI — Equinor, Aker BP, Yara and the North Sea

Oil and gas are the economic heart of Norway, and their offshore supply chain is one of the most demanding in the world. For newcomers: equipping a North Sea platform means thousands of perfectly traced orders, deliveries and invoices — hence heavy use of EDI. Equinor (ex-Statoil), Aker BP, Norsk Hydro and Yara combine EDIFACT for the supply chain with EHF/PEPPOL for invoices.

History — from 1969 oil to EPIM

The discovery of Ekofisk in 1969 launched the Norwegian oil industry. Statoil (1972, renamed Equinor in 2018) structured the sector. From the 1990s-2000s, EDI took hold to manage complex offshore supply chains. EPIM (E&P Information Management) then coordinated the sharing of licence and logistics data on the Norwegian continental shelf, pooling information across operators.

Governance — operators and EPIM

EDI governance in the sector is shared. The operators (Equinor, Aker BP, ConocoPhillips Norge…) impose their EDIFACT profiles and supplier portals. EPIM, the industry's common body, runs the data-sharing platforms (licences, logistics, environmental reporting). On the invoice side, EHF/PEPPOL conformance follows DFØ's national rules, as for any sector.

Technical schema — EDIFACT + OFTP2 + EHF

The Norwegian oil-and-gas EDI architecture layers three tiers:

• EDIFACT messages — ORDERS, DESADV, INVOIC for materials and services, often with sector subsets (offshore-specific qualifiers).
• OFTP2 over ENX — secure transport inherited from automotive/industry (Odette), with end-to-end acknowledgements, signature and encryption.
• EHF/PEPPOL — the invoice layer (UBL), interoperable with the rest of the Norwegian ecosystem.

Offshore supply chain vs retail

Adoption — operators and suppliers

• Equinor — leading operator, demanding supplier portal and EDIFACT profiles, EHF invoicing.
• Aker BP — major operator, deep EDI integration with its offshore subcontractors.
• Norsk Hydro — aluminium and energy, international EDIFACT industrial chains.
• Yara — fertilisers and ammonia, global chemical supply chain in EDIFACT, a pivot of the transition (green ammonia).

Common pitfalls

• Operator-specific profiles. Each operator imposes its EDIFACT subset and qualifiers; a generic message is rejected.
• Misconfigured OFTP2. Certificates, SSID/SFID and acknowledgements must be exact; an error blocks the ENX exchange.
• Confusing supply-chain and invoice flows. EDIFACT/OFTP2 for goods, EHF/PEPPOL for the invoice — two channels not to mix.
• HSE traceability. Omitting required references (certificates, batches) breaks offshore documentary compliance.
• Currency and Incoterms. Offshore contracts mix NOK, USD, EUR; a wrong Incoterm or currency skews the invoice.
