Question about meaning of Digitalarkivet.column

I have successfully found my Norwegian immigrant ancestors in the Digitalarkivet "Emigrants from Olso 1867-1930" database. Can someone help me understand the meaning of the "Remarks", "Freight" and "Line" columns? In my specific case: Remarks = 2320 Freight = Spd 173,24 Line = Oder My goal is to find the ship passenger list for this family. Thank you.
