Question 95Safety & Environmental - Assistant Engineer
70% to passTo prevent oil from escaping into the sea when ballasting through the cargo piping system, you should FIRST _______________.
Aopen block valves, then start the cargo pump
Bstart the cargo pump, then open sea suction valves
Copen sea suction valves, then start the cargo pump
Dopen sluice valves, then start the cargo pump
AI Explanation
The correct answer is B) start the cargo pump, then open sea suction valves. The reasoning is that by starting the cargo pump first, you create suction in the cargo piping system. This helps to prevent oil from escaping into the sea when you subsequently open the sea suction valves. Opening the sea suction valves first without the cargo pump running could allow oil to be drawn out into the sea. The other options are incorrect because: A) opening block valves first without the pump running would not create the necessary suction; C) opening sea suction valves first without the pump running could allow oil to escape; and D) opening sluice valves is not the correct step in this procedure.
