Question 86Safety & Environmental - Assistant Engineer
70% to passA gurgling noise is heard from within a cargo tank when discharging cargo, this would indicate that the _______________.
Apump discharge pressure is excessive
Bpump is sucking air
Ctank foot valve is partially clogged
Dtank liquid is too viscous
AI Explanation
The correct answer is B) the pump is sucking air. When discharging cargo, a gurgling noise from within the cargo tank indicates that the pump is sucking air, which can occur if the tank foot valve is not fully open or if there is a leak in the suction line. This allows air to be drawn into the pump, causing the characteristic gurgling sound. The other answer choices are incorrect because excessive pump discharge pressure, a partially clogged tank foot valve, or highly viscous cargo would not typically result in a gurgling noise from the tank.
