Verify the Integrity of Your Technical Documentation
A rigorous, independent audit to confirm compliance, identify non-conformities, and safeguard your operational and regulatory standing before an external inspection does it for you.
"In highly regulated industries like energy, a documentation audit is not a luxury. It is a necessity. It is the definitive proof that your information assets are not just present, but accurate, compliant, and fit for purpose, protecting your operations from significant financial and safety risks."

Understanding the discipline
What is a Technical Documentation Audit?
A Technical Documentation Audit is a systematic, independent, and documented process for obtaining audit evidence and evaluating it objectively to determine the extent to which audit criteria are fulfilled. In the energy sector, this means verifying that technical documentation from engineering drawings to operational manuals meets internal standards, industry regulations such as ISO 19650 and ISO 9001, and the legal requirements applicable to the facility.
The theoretical underpinning of a documentation audit is Risk Mitigation through Verification. Unlike a document assessment, which is diagnostic and strategic, an audit is forensic and detailed. It operates on the principle that critical information must be demonstrably accurate and accessible to prevent operational failures, ensure personnel safety, and maintain regulatory compliance. The audit evaluates four key dimensions simultaneously.
Accuracy and Completeness examines whether all required documents are present and whether they reflect the current as-built or as-operated state of the asset. Version Control verifies that the correct, approved versions of documents are in active use and that there is a clear audit trail of all changes. Compliance checks whether the documentation adheres to relevant industry standards, national regulations, and internal policies. Accessibility and Usability assesses whether authorised personnel can find and understand the information they need within the time constraints of their operational role.
Research in regulated industries consistently demonstrates the severe financial and reputational consequences of poor documentation quality. Non-compliance exposed during a regulatory inspection carries costs that far exceed what a proactive internal audit would have cost to identify and remediate the same issues. The audit is not the problem. The problem is always found before the audit, or during it.

The cost of regulatory non-compliance
In the energy sector, a failed documentation audit by an external regulator can have severe consequences ranging from substantial financial penalties to operational restrictions and reputational damage. The issue is not just the fine. It is the cascade of consequences that follows.
Consider an oil and gas operator undergoing a routine regulatory inspection. If the inspection reveals that critical safety documentation such as pressure vessel inspection certificates or hazardous area classifications is missing, outdated, or cannot be readily produced, the regulator can impose significant fines potentially exceeding €500,000. In extreme cases this leads to operational restrictions or a temporary shutdown until the documentation is brought into compliance. A proactive Documentation Audit identifies these vulnerabilities before an external regulator does, at a fraction of the cost and without the reputational consequences.
What a documentation audit actually produces
Every finding in a SøDera documentation audit is graded, evidenced, and traceable to a specific document, system, or process. Major Non-Conformities come with a remediation requirement. Observations come with a recommendation. Nothing is vague and nothing is left open to interpretation.
The report is structured to be useful to two different audiences: the technical team who will fix the issues, and the management team who needs to understand the risk exposure and sign off on the remediation plan.
Our methodology
The SøDera rigorous audit process
We conduct thorough and objective documentation audits that provide you with clear, evidence-based insights and an actionable remediation plan. Every finding is graded, evidenced, and prioritised so you know exactly what to address first.
Scope Definition
Working with you to define the audit scope, criteria, and target documentation sets. A well-defined scope ensures the audit focuses on the areas of highest operational and regulatory risk rather than producing a comprehensive but unfocused findings list.
Evidence Collection
Systematically gathering documentation, interviewing personnel, and reviewing digital systems. Evidence is collected against the defined audit criteria, not against an assumed standard. Every finding is traceable to specific evidence.
Compliance Verification
Cross-referencing documentation against relevant industry standards including ISO 19650 and ISO 9001, applicable regulations, and internal policies. Compliance verification is objective and criterion-referenced, not subjective.
Non-Conformity Identification
Documenting all discrepancies, gaps, and areas of non-compliance with clear evidence cited for each finding. Findings are graded as Major Non-Conformities, Minor Non-Conformities, or Observations, each with a recommended response.
Root Cause Analysis
Investigating the underlying reasons for identified issues rather than just cataloguing the symptoms. A Major Non-Conformity that results from a governance gap will recur unless the governance is fixed, not just the specific document.
Actionable Reporting
Delivering a comprehensive audit report with prioritised recommendations for remediation and improvement. The report is structured to be useful to both the technical team addressing the findings and the management team overseeing the response.
A pattern we see repeatedly
When a project nears handover with compliance gaps no one has verified
The Situation
On large energy infrastructure projects approaching their operational readiness date, we consistently see project teams that are unsure whether all critical documentation meets the regulatory requirements for handover and operation. The EPC contractor asserts compliance. The project team has no independent basis to verify it. And the cost of discovering non-conformities during a formal regulatory inspection rather than during an internal audit is orders of magnitude higher.
What Good Looks Like
A comprehensive Documentation Audit conducted before the final regulatory inspection focuses on safety-critical systems, operational manuals, and regulatory compliance documentation. Major Non-Conformities are identified, including missing certification documents and inconsistent version control for critical P&IDs. Each finding is graded, evidenced, and assigned a remediation priority. The project team receives a clear list of actions before the regulator arrives.
The Outcome
When an independent documentation audit is completed before the regulatory inspection, all identified non-conformities are resolved before they are exposed externally. The facility commences operations on schedule without the fines, delays, or reputational consequences of a failed external inspection. The audit report itself becomes a demonstration to regulators and insurers that the operator manages documentation to a verifiable standard.
Why partner with us
Expertise you can measure. Trust you can verify.
SøDera's documentation audit practice is built on the same foundation as our RDS audit practice: independence, deep domain knowledge, and a commitment to findings that are specific enough to be actionable rather than generic enough to be safely ignored. We have seen what regulators look for in energy sector documentation audits and we know exactly where the gaps typically are.
Our independence is the foundation of every audit we deliver. We have no commercial relationship with the contractors whose work we are verifying and no interest in the outcome of the findings beyond giving you an accurate picture of where your documentation stands against the standard.

Pre-regulatory inspection
Identify and remediate non-conformities before an external regulator does. The cost of a proactive internal audit is always lower than the cost of a failed external inspection.
Pre-handover verification
Verify that documentation delivered by an EPC contractor at handover is complete, accurate, and compliant before final payment is released and operational responsibility transfers.
Periodic compliance assurance
Documentation quality degrades over time without active governance. Periodic audits identify emerging non-conformities before they become regulatory exposure and reinforce the governance habits that prevent recurrence.
Post-incident review
Following an operational incident, a documentation audit establishes whether inadequate or inaccurate documentation contributed to the event and identifies the corrective actions required to prevent recurrence.
