What maneuver is indicated by the signalman making a chopping motion with a RED signal device in the right hand on a GREEN one in the left hand?

The maneuver indicated by the signalman making a chopping motion with a red signal device in the right hand while holding a green one in the left hand signals the action to trip a pelican hook. In maritime operations, a pelican hook is a type of hook used for securing loads, and tripping it is necessary to release the load in a controlled manner. The combination of the red chopping motion typically indicates a command or directive with urgency, while the green signifies the operation's context, establishing that the necessary release of the load is to occur. This signal is crucial in maintaining safety and coordination during operations involving heavy lifting or cargo transfer, particularly when working with ships and flat-deck lifting systems. Understanding these signals is essential for safe and effective operations at sea, particularly in replenishment and cargo handling scenarios.
