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 D) inerted.
For a crude oil wash system to be operated safely, the cargo tanks must be inerted, meaning they are filled with an inert gas like nitrogen or carbon dioxide. This creates an oxygen-depleted, non-flammable atmosphere inside the tanks. Inert gas systems are required by regulations to prevent the risk of explosions or fires during crude oil washing operations.
The other options are incorrect because: A) opening the tanks to the atmosphere would create a flammable environment, B) the tanks must be gas free (not containing flammable vapors) but inerted, and C) the tanks do not need to be full of cargo, they can be partially filled.
