AI Explanation
The correct answer is B) ensure fouled heating coil returns from fuel tanks do not contaminate boiler feed water. The purpose of a contaminated steam system is to prevent contamination of the boiler feed water from the return of fouled heating coils that may have been exposed to fuel oil or other contaminants. This is important to maintain the purity of the boiler water and prevent damage to the boiler and associated equipment. The other options are incorrect as they do not accurately describe the primary purpose of a contaminated steam system on a vessel.
