Oil Record Book Part I · MARPOL Annex I

Every capability built for maritime operations

From entry logging at sea to real-time fleet compliance dashboards ashore, ShipORB covers the entire ORB lifecycle.

Jump to
Offline-first

Works at sea, even when nothing else does.

ShipORB operates with full functionality - log entries, sign records, export PDFs - entirely offline. When satellite connectivity returns, NATS JetStream handles all synchronisation automatically.

  • Full CRUD operations with zero internet
  • SQLite on-vessel database - bulletproof local storage
  • Automatic NATS JetStream sync on reconnect
  • USB export for air-gapped inspections

Tamper-proof

Cryptographic integrity that auditors trust.

Every ORB entry is chained to the previous one using SHA-256 hashes, creating an unbreakable sequence. Each entry is individually signed with ECDSA P-256 digital signatures.

  • SHA-256 hash chain - each entry links to the last
  • ECDSA P-256 per-officer digital signatures
  • Append-only SQL triggers - no deletions, no edits
  • FIPS 140-3 compliant cryptographic modules
