By regulation, cargo tank atmosphere must be inert before and during which operation?
AI Explanation
The correct answer is D) All of the above.
According to the regulations, the cargo tank atmosphere must be inert before and during topping off, stripping, and crude oil washing operations. This is a safety precaution to prevent the buildup of flammable vapors in the tank, which could lead to an explosion or fire hazard. The inert gas (typically nitrogen or carbon dioxide) displaces the oxygen and makes the tank atmosphere non-combustible. Maintaining an inert atmosphere is crucial during these critical cargo handling operations to ensure the safety of the vessel and crew.
