Statement of Facts

Statement of Facts (SoF) is a report listing all events during a ship's stay in port in chronological order and is used for the calculation of the lay time.
The Statement of Facts has usually a standardised form. It is written by the port agent or the shipmaster. It lists such things as the arrival and departure time and the time at the berth, the times in which cargo is loaded or unloaded, weather and other conditions that affect the cargo time, whether tugboats are used, etc. A frequently used SoF form is that of BIMCO.
