What pressure shall cargo hoses carried on tank vessels be able to withstand?
AI Explanation
The correct answer is D) at least 150 psi.
According to the regulations in 46 CFR 39.20-1, cargo hoses carried on tank vessels must be able to withstand a minimum pressure of 150 psi. This is to ensure the hoses can safely handle the high pressure required for the loading and unloading of cargo, especially hazardous liquid cargoes. The other options (75 psi, 100 psi, 120 psi) are insufficient and do not meet the regulatory requirement for cargo hoses on tank vessels.
