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.
Turn thousands of scattered maintenance documents into one cross-referenced, audit-ready record.
01.
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.
The DID and VC Ledger issues credentials to inspectors and technicians, so every record carries a provable, verifiable author.
03.
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.
Missing or inconsistent records are surfaced before an audit, addressing the gap that can otherwise halt plant operation.
05.
Regulators query the anchored maintenance history directly, cutting the document retrieval that stretched audits into weeks.
06.
Each component's full inspection and maintenance history is retrievable on demand, supporting both audits and post-incident investigations.
Follow a single component's maintenance record from capture through credentialed sign-off to a regulator audit query.

Cerulea decomposes maintenance auditing into modular contracts. Each layer anchors DMS records, verifies authorship, checks completeness, and exposes a cross-referenced trail.
Anchored maintenance auditing is a horizontal capability. Here is how different actors in plant operations put the shared ledger to work.
Anchor existing DMS records and surface gaps before an audit, protecting operating licenses from the missing or inconsistent records that can halt a plant.
Key Asset Types
Sign off inspections with verifiable credentials, giving their work a provable author and a permanent place in the plant's audit trail.
Key Asset Types
Complete outage and safety audits in days from cross-referenced on-chain records, replacing document retrieval delays with a real-time query.
Key Asset Types
Whether you are bridging SAP PM and inspection software or capturing sign-offs from a field device, Cerulea routes both into one audit trail.
For plants on SAP PM and inspection platforms. Records are translated into signed on-chain anchors through the API gateway automatically.

Building a maintenance audit trail with DMS anchoring, verifiable credentials, and completeness checking from scratch requires specialised engineers and long integration cycles. Calculate your exact deployment speed using Cerulea.

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.
