The correct answer is D) Stripping systems are generally eliminated for the purposes of cargo handling. This is correct because deep well self-priming pumps are commonly used for cargo handling on product tankers and medium-sized crude ships. These pumps do not require a separate stripping system, as they can effectively remove the final remnants of cargo from the tank. The elimination of a dedicated stripping system simplifies the cargo handling process and reduces the overall equipment required on the vessel. The other options are incorrect: A) Deep well pumps remain popular for cargo handling, B) Cargo is not always loaded via the discharge line, and C) Overheating can potentially damage the pump if not properly operated.
