🔍 Key Concepts

• Main cargo pumps vs. stripping pumps – what each one is designed to do during discharge • Residue/remaining oil in a tank – why the main pumps can’t pick it up and what special system is used • Cargo piping and main discharge line – how stripped cargo usually reaches shore

💭 Think About

• Think about what happens as a tank gets almost empty: what limitation of the main cargo pumps makes a separate stripping system necessary? • From an operational efficiency standpoint, when is it most practical to run the stripping system – only after all tanks are done, or while other tanks are still being discharged? • Is it more common to consolidate small remainders into one tank first, or to use the stripping system to move them straight into the existing discharge path to shore?

✅ Before You Answer

• Make sure your choice involves a stripping action, not just relying on the main cargo pumps alone. • Check whether the description shows the stripped oil going into the same main discharge line to shore or being moved to another tank first. • Verify that the sequence described is practical during a real discharge, not something that would require stopping everything just for a small amount of cargo in each tank.
