The method of fabricating fire resistant tank apparatus adapted for transportation and for installation above-ground to receive and dispense a liquid hydrocarbon or hydrocarbons, includes providing a metallic tank assembly having lightweight wall means defining inner wall means, intermediate wall means and outer wall means, and spacing the wall means to form primary space between the intermediate wall means and the inner wall means, and secondary space between the intermediate wall means and the outer wall means; providing access porting to a tank interior defined by the assembly; a bottom wall defined by the assembly located to support the assembly at an installation side; and providing thermal barrier material in one of the first and second spaces to effectively define a shell about the tank interior. In addition, fire resistant material may be applied to the outer side or sides of the outer walls and hardened to define a relatively lightweight shell enclosing the tank assembly. The method provides structure that resists severe heat invasion in the form of radiation, convection and conduction to maintain liquid hydrocarbon in the innermost tank isolated from such invasion, the structure also being bullet resistant.
