2. Storage tank - Wikipedia

   en.wikipedia.org/wiki/Storage_tank

   Storage tanks are available in many shapes: vertical and horizontal cylindrical; open top and closed top; flat bottom, cone bottom, slope bottom and dish bottom. Large tanks tend to be vertical cylindrical, with flat bottoms, and a fixed frangible or floating roof, or to have rounded corners transition from the vertical side wall to bottom ...

3. Mud tank - Wikipedia

   en.wikipedia.org/wiki/Mud_tank

   Mud tanks are divided into square tanks and cone-shaped tanks according to the shape difference of the tank bottom. The body of the tank is made by welding the steel plate and section, using the smooth cone-shape structure or the corrugated structure. The mud tank surface and passages are made of slip resistant steel plate and expanded steel ...

4. Vent (submarine) - Wikipedia

   A fixed roof tank is a type of storage tank, used to store liquids, consisting of a cone- or dome-shaped roof that is permanently affixed to a cylindrical shell. Newer storage tanks are typically fully welded and designed to be both liquid- and vapor-tight. Older tanks, however, are often riveted or bolted, and are not vapor tight.

   The accident was ultimately ruled to be the result of poor engineering judgement in attaching the vernier helium vent line to the bottom of the RP-1 tank. This was not the first occurrence of the failure mode; Missile 6C had exploded on the test stand at Sycamore Canyon the previous March due to the vernier start tanks being connected incorrectly.
