Floating roof for liquid storage tanks - Wiggins, John H.A floating roof of the kind described in claim 1, provided with means for automatically increasing the pitch or angle of a radially inclined drainage surface of said trough when the weight or load of the roof is transferred to the bottom of the tank. 6. A floating roof for liquid storage tanks, comprising a stiff peripheral pontoon whose bottom Foundations of aboveground steel tanksStiffening of membrane of single deck floating roof. Methods of erection. Typical damages of aboveground steel tanks. This level difference is remarkable in the fuel oil tanks where pump always must be under the liquids (h 0,7m). It should not be applied to the new build tanks. Internal Wind Pressures and Buckling Behavior of Large In this paper, two practical large cylindrical floating-roof tanks with diameters of 60 m and 100 m are selected as research objects. Wind pressures on the internal wall of tank s
