A ship engaged on an international voyage may switch off its LRIT equipment only when it is permitted by its Flag Administration, in circumstances detailed in SOLAS V/19:
- Where international agreements, rules or standards provide for the protection of navigational information (WARSHIPS for example)
- In exceptional circumstances and for the shortest duration possible where the operation is considered by the master to compromise the safety or security of the ship.
- When a ship is undergoing repairs in dry-dock or in port or is laid up for a long period, the master may temporarily stop the transmission.
