🔍 Key Concepts

• Cargo discharge system layout – relationship between main cargo pumps, stripping pump, and stripping line • Function of stripping operations – removing remaining liquid that main pumps cannot pick up • Typical problems in stripping systems – air in pump (loss of prime), valve lineup, and pump/line condition

💭 Think About

• Ask yourself: If the main discharge seems okay but the final cleanup (stripping) is slow, which part of the system is most likely at fault – the main pumps, the stripping pump, or the line-up? • Think about what it means when a pump is "not primed" and how that would show up in tank stripping progress. • Consider whether high main pump pressure or a cross-connection would cause slow stripping, or a different kind of problem (such as pressure issues or wrong tank being pumped).

✅ Before You Answer

• Verify which equipment actually handles the last few inches of cargo in the tank – main pump or stripping pump. • Check your understanding of what happens when a stripping pump loses its prime – does it move liquid effectively or mostly air? • Confirm whether a cross-connection of lines would typically cause delay in stripping, or misdirection/recirculation of cargo instead.
