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

Certificates · in development

Survey windows and expiry dates for the certificates a ship carries.

The certificates module runs in the ShipORB demo today; it isn't in the ship-side or shore products yet. It keeps each vessel's statutory, class and insurance certificates in one register beside the Oil Record Book, and lists the certificates a ship of that type and gross tonnage would normally need. It doesn't account for trading area or flag exemptions. A certificate on that list with no record shows as Required, not held.

  • Annual survey windows from the dates you enter: three months either side of each anniversary date
  • The intermediate survey, where the certificate has one, falls in the annual window at the second or third anniversary date
  • An extension the Administration has granted, once you enter it: the extended expiry date, with its basis in a note
  • The IOPP Certificate (MARPOL Annex I regulation 7) in the same read-only inspector view as the Oil Record Book

It doesn't replace the certificates carried on board or the Administration's records, and no flag Administration or classification society has reviewed it.
