Load on Top (LOT): defined as both a procedure and a practice. Procedure: Load on top is the shipboard procedure of collecting the settling water and oil mixtures, resulting from ballasting and tank cleaning operations (usually in a special slop tank or tanks), and subsequently loading cargo on top of the slops and pumping the resultant mixture ashore at the discharge port. Practice: Load on top is the act of commingling onboard quantity with cargo being loaded. The onboard quantity is the remnant of the previous cargo or part load into the tank.
