Load On Top
The discharges from seawater washing were still considered a problem and during the 1960s the load on top approach began to be adopted. The mixture of cleaning water and residue was pumped into a slop tank and allowed to separate into oil and water during the journey. The water portion was then discharged, leaving only crude oil in the slop tank. This was pumped into the main tanks and the new cargo loaded on top of it, recovering as much as 800 tons of oil which was formerly discarded.
