Answer & Explanation
The correct answer is Option B: Before starting the cargo operation and after the cargo operation is completed.
Cofferdams adjacent to cargo tanks must be purged and checked before cargo operations commence to ensure no leakage is present, and again after completion to verify the integrity of the bulkheads during the operation. This is a vital practice for preventing pollution and fire hazards.
