Why owner standards cause most valve deviations
A Gulf tender for valves usually calls up an API product standard, then an owner standard, then a project specification and datasheets. The API standard is familiar to every manufacturer. The owner layer is where requirements differ from one operator to the next, and where a standard catalogue valve most often falls short.
How you get the documents varies. ADNOC publishes many of its AGES specifications and guidelines on its website, for example its materials selection guidelines (ADNOC); Saudi Aramco and Shell standards are usually issued to vendors with the tender. This page does not reproduce or summarise any owner-standard text. It lists the kinds of requirement owner standards commonly add, so you know where to look, and it is not a description of any one operator's documents.
Common deviation sources in owner valve specifications
| Area | What owner standards commonly add | What to check in your offer |
|---|---|---|
| Approved vendors | Approved manufacturer or vendor lists; Saudi Aramco, for example, keeps a valve approved-manufacturer list that its Valves Standards Committee reviews (Valve World Americas) | Your approval status for the exact product line; flag any pending approval |
| Materials | Material selection rules for the operator's service conditions; ADNOC, for example, publishes materials selection guidelines (ADNOC) | Every pressure-containing and trim material on the datasheet |
| Sour service | Requirements beyond NACE MR0175 / ISO 15156, such as extra hardness checks or testing | Whether your sour-service qualification covers the added tests |
| Low-temperature service | Impact testing at specified temperatures, sometimes cryogenic testing | Impact test temperature and whether a low-temperature valve test is required |
| Testing | Supplementary pressure tests, gas seat tests, extended durations | Tests beyond the API base test, and who witnesses them |
| Fire and fugitive emissions | Named fire-test and fugitive-emission qualifications and classes | Your qualification reports and their range; see ISO 15848-1 |
| Non-destructive examination | More extensive or stricter NDE on castings and welds | NDE extent and acceptance levels against your standard practice |
| Positive material identification | PMI on alloy parts | Whether PMI is in your ITP and certificates |
| Coatings | Owner coating systems for the site environment | Your standard paint system vs the owner's |
| Inspection | Witness and hold points, third-party inspection | Your ITP and the cost of witness points |
| Certificates | EN 10204 type 3.2 for some parts | 3.1 vs 3.2; see EN 10204 3.1 vs 3.2 |
| Documentation | Owner datasheet formats, document numbering, data books | Your vendor data requirements list answer |
| In-country value | ADNOC's In-Country Value (ICV) programme: bidders without an ICV certificate are treated as 0% ICV, and ICV is weighed in tender evaluation (ADNOC) | Whether you hold a current ICV certificate and where the tender scores it |
How the three families differ in practice
Each operator structures its standards differently, and tenders for the same valve type can call up quite different documents. Treat each as its own checklist rather than assuming that compliance with one means compliance with another. Some projects also call up industry supplementary specifications instead, such as IOGP S-562 (JIP33), which adds requirements to API 6D for trunnion-mounted ball valves (IOGP); check which applies.
| Family | Operator | What to confirm in every tender |
|---|---|---|
| AGES (ADNOC engineering standards and specifications) | ADNOC | Which AGES documents and revisions apply; any project-specific overrides |
| SAES (Saudi Aramco Engineering Standards) | Saudi Aramco | Which SAES and related specifications apply; approved-manufacturer status |
| DEP (Design and Engineering Practice) | Shell | Which DEPs and amendments apply, and the revision the tender names |
A review sequence for Gulf valve tenders
- List every document the requisition calls up, with revision: API or ISO base standard, owner standards, project specification, datasheets, addenda.
- Confirm the order of precedence. See governing-document precedence.
- Check approved-vendor status first; if you are not approved for the product line, everything else may be moot.
- Go through the owner standard clause by clause against your datasheet, using the categories above as a prompt.
- Record each gap in your technical deviation list with a justification and cost of withdrawal.
- Check the inspection and documentation requirements last, because they drive cost and schedule.
Use the datasheet vs specification checklist and the free templates for the row-by-row work, and API 6D for the base standard.
Context: ADIPEC and the Gulf valve market
ADIPEC runs at ADNEC, Abu Dhabi, on 2-5 November 2026, with 2,250+ exhibiting companies and 54 NOCs, IOCs, NECs and IECs taking part (ADIPEC). The Middle East valve market is estimated at about $2.9bn in 2025, growing 6.6% a year (GMI). Gulf owner standards are also a selling point for AI tools: ValveIQ, for example, markets built-in AGES, SAES and DEP knowledge (ValveIQ).
