ShipORB has been a game-changer for our fleet operations, eliminating our reliance on paper ORBs and reducing PSC detention risk dramatically.

Alexei Petrov

Fleet Superintendent, Baltic Shipping

The offline-first design means my engineers can log entries even in the middle of the Indian Ocean. It just works, no excuses needed at inspections.

Maria Kowalski

Chief Engineer, MV Pacific Star

The cryptographic audit trail is exactly what we need. Port state control officers can verify integrity on the spot - no more questioning if records were altered.
