A storage reservoir for oil is assembled from plastic strips to float on the surface of a water basin within a dam made waterlight by a lining of plastic sheeting. The plastic material for the storage bladder is preferably polyethylene with a specific gravity of less than 1 g/cm3 so that it floats on water when empty or full. The strips are not reinforced panels of over 2 mm thickness with an elongation at break of over 100% (200%). This design ensures that no folds arise during the critical initial filling phase. It collapses during discharge to a flat bladder without creases. When full, it can be walked on for inspection because the panels are tread resistant. |
