What should be done once the vessel is berthed and will not leave port for several weeks?

Once a vessel is berthed and will not leave port for an extended period, the GMDSS Radio Operator has specific protocols to follow to manage the equipment effectively. Turning off the power is essential for conserving energy and preventing unnecessary wear on the systems. The operator can log out of the communications systems and switch off the GMDSS equipment, ensuring that the vessel's systems remain in a safe and secure state until it is ready to depart again.

It's crucial to understand that while the GMDSS equipment must be maintained and operational when at sea or during emergencies, it can be powered down when the vessel is docked, provided that proper procedures are followed. This practice helps in both energy conservation and safety, as powered down equipment reduces the risk of malfunctions or accidental transmissions while the vessel is at the dock.

The other options involve actions that are not standard for a vessel that will be in port for an extended duration. For instance, notifying the NCS or broadcasting an all-ships alert is unnecessary unless there is a specific situation requiring such communication while at port. Similarly, powering down the Inmarsat-C system might require certain protocols to be adhered to, depending on the specific setup and operational procedures in place.
