In oil diary all be oil - and fuel movements within a vessel recorded.

Oil movements on board are:

• Bilge water over Entöler overboard
• Filling the fuel tanks , such as the settling tanks of double-bottom tanks
• Fuel day tanks through separators
• Bunkering of fuel

Very important: the waste oil disposal in the port .

The oil diary should prove that no oil was pumped overboard at sea and that at least 3% of the bunkered fuel was handed over to disposal companies as certified waste oil .

There is also an oil diary on tankers in which only all processes on board a tanker that affect the cargo are recorded. This includes, for example, where and how much cargo was taken over and where again, how the ship's tanks were cleaned and what happened to the washing residue .
