The failure of the floating cover of a vertical cylindrical tank

Abstract

The location of oil tanks for the storage of volatile hydrocarbons could be done in geographical areas where the standard unit weight of the snow layer on the horizontal surface of the land reached 1500 ... 2000 N / m2 . The snow layer deposited on the floating cover under heavy weather conditions can cause a compressive force between 4500 and 6000 N / m2 . This creates problems in the operation of the tank and consequently the constructive structure of the floating cover can not bear this unitary load from the snow load, inevitably causing the damage. The capacities of the floating cover should be considered not only in terms of limitations on load-bearing considerations in general, but also in terms of the distribution of loads on the surface of the floating cover. The paper presents the aspect of the failure of a floating cover of a vertical cylindrical tank used to store liquid hydrocarbons under heavy climatic conditions.
