Aker BP is one of the largest independent oil and gas operators on the Norwegian Continental Shelf, developing and operating offshore fields across the North Sea. When a project's storage tanks are ultimately destined for an Aker BP platform or onshore support facility, "approved supplier" isn't a marketing phrase — it's a specific, audited status the client grants to individual manufacturers after a formal qualification process. For procurement and engineering teams in Italy sourcing storage tanks for this kind of work, understanding what that process actually involves is far more useful than searching for a badge.
This article explains what Aker BP vendor approval covers, the engineering baseline it's built on, and what to look for when qualifying a storage tank manufacturer for Aker BP-linked or -grade projects.
Aker BP maintains its own vendor qualification process, which involves a detailed audit of a manufacturer's quality management system, welding procedures, plate and material control, non-destructive testing capability, and documented fabrication history. That audit is typically carried out by the client's own engineering and inspection teams or a third-party inspection agency acting on its behalf, and the resulting approval is specific to the manufacturer.
Because this status is granted directly by Aker BP to a named manufacturer, it isn't something any supplier can claim without going through that process. What buyers researching suppliers can assess independently — before any formal audit — is whether a manufacturer's engineering and quality practices are already built to the level Aker BP requires.
Regardless of a tank's final destination, the technical requirements that underpin Aker BP-grade fabrication are largely the same requirements that govern quality storage tank manufacturing generally, with additional weight given to offshore-specific standards:
API 650 for atmospheric storage tanks and API 620 for low-pressure tanks, or EN 14015 as the European equivalent, are the standard reference codes, with NORSOK standards and Aker BP's own engineering specifications layered on top for Norwegian Continental Shelf projects.
Full mill test certificates and heat-number traceability carried from raw plate through to the finished, welded tank shell, with additional documentation for offshore-service or low-temperature toughness requirements.
Design that accounts for seismic loading, wind loading, settlement, and, for offshore or exposed installations, additional environmental and structural criteria specified by Aker BP.
WPS and PQR documentation, with welders individually qualified under ASME Section IX or EN ISO 9606, and additional qualification where NORSOK M-101 requirements apply.
Radiographic testing of shell welds, vacuum box testing of floor welds, and magnetic particle testing where applicable, with expanded scope where offshore service conditions demand it.
A full water test of the assembled tank shell before commissioning.
Hold-point sign-off from an accredited inspection body such as Lloyd's Register, Bureau Veritas, TÜV, or DNV at critical stages of construction, with DNV frequently specified for Norwegian offshore work.
A manufacturer that applies this level of control as standard practice — not only on projects with a named end client — is generally the one positioned to succeed if and when a formal Aker BP audit takes place.
Notdstone manufactures customized storage tanks for the safe storage of liquids, gases, chemicals, and petroleum products, serving Italy, the GCC, and international markets, with more than three decades of engineering experience across the team. Our fabrication and QA/QC processes are structured around the technical baseline described above — documented material traceability, ASME IX-qualified welding, comprehensive NDT, and hydrostatic testing before delivery.
To be clear with buyers researching this topic: formal vendor approval with Aker BP is issued directly by Aker BP to specific manufacturers following its own audit process, and we're not claiming that status here. What we can speak to with confidence is the engineering rigor our storage tanks are built to on every project.
ASME Section VIII-compliant vessels engineered for safe containment under demanding pressure and temperature conditions.
TEMA-designed shell-and-tube units for heating, cooling, condensation, and energy recovery.
API 650/620-referenced tanks for liquids, gases, chemicals, and petroleum products.
Distillation, absorption, and stripping columns engineered for process efficiency in chemical and petrochemical service.
Custom-engineered reactors for controlled chemical processing and reaction management.
Factory-assembled modular skids integrating vessels, pumps, piping, and instrumentation to compress site installation time.
It means the manufacturer has been formally audited and accepted by Aker BP, covering their quality system, welding procedures, and testing capability for tank fabrication.
API 650/620 or the European equivalent EN 14015 are the primary reference codes, typically supplemented with NORSOK standards for offshore Norwegian Continental Shelf work.
For aggressive stored products or low-temperature offshore environments, yes — stainless steel or other corrosion-resistant alloys may be specified instead of standard carbon steel.
Yes, provided their code compliance, material traceability, and third-party inspection arrangements meet the project specification and export logistics support delivery of large-diameter tank components to the relevant fabrication yard or site.
Ask for written confirmation of the approval status and its exact scope — which equipment categories it covers — rather than relying on a general claim.
If your project requires storage tanks engineered to API or EN standards and manufactured under documented quality control, our engineering team can review your process requirements and provide a project-specific proposal. Get in touch with Notdstone to discuss your requirements.
