While your vessel is docked port side to a wharf, a sudden gale force wind causes the vessel's stern lines to part. The stern begins to fall away from the dock, and no tugs are immediately available. Which measure(s) should you take FIRST?

Correct Answer: Option A — Shut down any cargo transfer that's in progress.

Cargo operations present immediate environmental and fire risks if lines part and the vessel moves. Standard marine safety and pollution prevention protocols require immediate emergency shutdown of cargo transfer before addressing line repairs or propulsion.
