Who is responsible for the key to the lock securing the throttles when the ship is docked?

The Engineer Officer is responsible for the key to the lock securing the throttles when the ship is docked due to their specific role in overseeing the engineering department and the operation of the ship's machinery. This responsibility includes ensuring the safety and operational readiness of the ship's propulsion systems. Since the throttles control the power and speed of the vessel, securing them when the ship is not in operation prevents unauthorized access and potential mishandling.

In the context of maritime operations, the Engineer Officer’s role involves close supervision of the engine room and propulsion systems, which directly correlates to the management and security of throttle controls, especially during periods when the ship is docked. Assigning this responsibility to someone who is trained to understand the implications of unauthorized throttle access aligns with industry best practices for safety and operational integrity.
