Question 29Safety & Environmental - 1st Asst/Chief

The correct answer is B) the pump. In the case of an emergency pump control used as the emergency shutdown on a tank vessel, it must stop the flow of oil through the pump. This is because the pump is the primary source of power for the oil flow, and shutting down the pump is the most effective way to immediately stop the flow of oil in an emergency situation. The other options are incorrect because: A) the main deck manifold is not the source of the oil flow, C) shutting down the facility would not directly impact the oil flow, and D) using a means that is not dependent on electrical power is not specified as the requirement in this case.
