Maintenance Audit Layer

Anchor every inspection.
Clear the audit in days.

Stand up a nuclear plant maintenance audit trail network where existing document management data is anchored on-chain and inspection credentials are verifiable. A regulatory audit team completes a pre-refueling outage review in days instead of weeks, with every maintenance record cross-referenced and complete.

The Foundation

The Execution Mechanics

Turn thousands of scattered maintenance documents into one cross-referenced, audit-ready record.

01.

DMS Anchoring

The External Data Oracles module anchors records from the plant's document management systems by digest, so existing maintenance data becomes tamper-evident without replacing the DMS.

02.

Verifiable Inspection Credentials

The DID and VC Ledger issues credentials to inspectors and technicians, so every record carries a provable, verifiable author.

03.

Cross-Referenced Trail

The Audit Logs module links records across components and systems, so an auditor follows one thread instead of cross-referencing multiple document stores by hand.

04.

Completeness Check

Missing or inconsistent records are surfaced before an audit, addressing the gap that can otherwise halt plant operation.

05.

Real-Time Regulator Access

Regulators query the anchored maintenance history directly, cutting the document retrieval that stretched audits into weeks.

06.

Component History

Each component's full inspection and maintenance history is retrievable on demand, supporting both audits and post-incident investigations.

The Maintenance Audit Lifecycle

Follow a single component's maintenance record from capture through credentialed sign-off to a regulator audit query.

Smart Contract Anatomy

Cerulea decomposes maintenance auditing into modular contracts. Each layer anchors DMS records, verifies authorship, checks completeness, and exposes a cross-referenced trail.

Applicability Across the Spectrum

Anchored maintenance auditing is a horizontal capability. Here is how different actors in plant operations put the shared ledger to work.

Plant Operators

Anchor existing DMS records and surface gaps before an audit, protecting operating licenses from the missing or inconsistent records that can halt a plant.

Network & Execution Architecture

Whether you are bridging SAP PM and inspection software or capturing sign-offs from a field device, Cerulea routes both into one audit trail.

Track A: Document System Bridging

For plants on SAP PM and inspection platforms. Records are translated into signed on-chain anchors through the API gateway automatically.

Track B: Credentialed Field Capture

For technicians in the field. A credentialed device signs each inspection sign-off directly to the audit trail.

Technical Methodology

The legacy timeline reflects regulated recordkeeping integration benchmarks. Anchoring multiple document systems, building custom credential and completeness logic, and shipping a regulator view for an average plant takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your record and credential rules into pre-audited WebAssembly binaries and provisions the audit ledger instantly.
