PROBLEM TO BE SOLVED: To provide an oil retaining wall integrated tank which does not require a large site and in which a dangerous object gathered in the oil retaining wall does not cause environmental pollution by penetrating the ground and there is no risk causing a big fire by the dangerous object gathered in the oil retaining wall when a leaked tank is ignited. SOLUTION: The problems existed in a conventional oil retaining wall is solved by covering the whole perimeter of the tank completely with a reinforced concrete 3 having equivalent strength to the oil retaining wall, close to a main tank 1 and the covered concrete can restrain heat conduction from a neighboring fire to the tank body (main tank) and play a role to protect the tank body from outside impact by a falling object or the like. Also an emergency pressure release mechanism 6 or an explosion proof structure is provided. COPYRIGHT: (C)2006,JPO&NCIPI
