The plate thickness in the bottom course was 21mm and 6mm in the top course.The thicknesses of courses 2 to 5 lay in between these.The tank capacity was 16000m 3 or 16 million litres and until 1986 it had been used to hold distillate oils and heavier distillates.In 1986 the tank was taken down by oxyacetylene cutting adjacent to the original welds and then reassembled by welding in Floreffe,keeping the plates
