70% to pass

In accordance with regulations, what is the required bursting pressure of a cargo hose used for transferring liquefied gases?

A 4 times the pressure of the cargo pump used for transferring
B one half the designed working pressure
C 5 times the maximum working pressure on the hose during cargo transfer
D 5 times the minimum working pressure on the hose during cargo transfer
AI Explanation

The correct answer is C) 5 times the maximum working pressure on the hose during cargo transfer. This is in accordance with the regulations for liquefied gas cargo transfer hoses, which require the hose to have a bursting pressure of at least 5 times the maximum working pressure during cargo transfer. This ensures a high safety factor in case of unexpected pressure spikes or other stresses on the hose. The other options are incorrect because A) does not account for the required 5x safety factor, B) only requires half the working pressure which is not sufficient, and D) refers to the minimum working pressure which is not the relevant specification.
