Question 146Safety & Environmental - 1st Asst/Chief70% to pass

In order for you to operate your vessel's crude oil wash system, the cargo tanks to be washed must be _______________.

AI Explanation
The correct answer is B) inerted. The cargo tanks to be washed as part of a crude oil wash system must be inerted, meaning the tanks are filled with an inert gas like nitrogen or carbon dioxide. This is a critical safety requirement to prevent the buildup of flammable vapors that could lead to an explosion or fire during the washing process. Tanks cannot be full of cargo, open to the atmosphere, or gas free, as those conditions would create a hazardous environment for the crude oil wash operation.
