There is also a small diameter line which is used to discharge last part of the cargo from the ship is called as MARPOL line .
When cargo discharged has been completed on a cargo system, the pipeline system should also be discharged ashore. The ideal arrangement for this operation is a stripping system which includes a separate, small diameter discharge (MARPOL), line to the midship manifold, with connections to each cargo manifold outboard of the manifold valve.
