Automatic shutdown systems independent of operator intervention: how to ensure that it will work correctly?

Option D: If the ship and shore shutdown circuits are to be linked their operation should be checked before cargo transfer begins; if not, the terminal should be informed of the closing rate of the ship's valves.

Ensuring automatic shutdown systems work correctly involves verifying the accuracy of the activation point and performing simulation checks upon recommissioning. This proactive approach guarantees the system will function as intended during critical overfill situations, as per safety system design and testing protocols.
