For vertical vessels, which is commonly used to support the vessel from the base?

• A. Skirt or Legs
• B. Trunnion Supports
• C. Beams and Pedestals
• D. Saddle Supports

Answer: (A)

Vertical vessels are most safely and stably supported from the base with a skirt or legs. This setup transfers the vessel’s entire weight directly into the foundation through a rigid, upright structure that stays attached to the bottom of the vessel, while leaving room under the vessel for inspection, drainage, insulation, and piping connections. Skirts or legs also accommodate thermal expansion and seismic movements and can be anchored firmly with foundation bolts. Trunnion supports are used when a vessel needs to pivot or rotate, which is typical for horizontal configurations, not for vertical bases. Saddle supports cradle the vessel along its sides and are common for long horizontal pipes or vessels, not for supporting a tall vertical vessel from the base. Beams and pedestals can provide support, but they’re not the standard base solution for vertical vessels, making skirt or legs the best choice.
