Question 2591 Deck General

The correct answer is A) 5 times the maximum working pressure on the hose during cargo transfer. According to regulations, cargo hoses used for transferring liquefied gases must have a bursting pressure of at least 5 times the maximum working pressure on the hose during cargo transfer. This is to ensure a high safety factor and prevent the hose from bursting under the high pressures involved in liquefied gas transfer. The other options are incorrect because: B) one half the designed working pressure is too low, C) 4 times the pressure of the cargo pump is not the correct criteria, and D) 5 times the minimum working pressure is less stringent than the requirement for 5 times the maximum working pressure.
