A.R. Watson, Group has been safely and successfully lifting Above Ground Storage Tanks (AST) for 45 years. Over this period of time A.R. Watson has continually modified its Engineering and updated its lifting procedures with the latest technology while always focusing on our clients concerns for cost and safety.
The Benefits
Standards and Practices
Tank lifting technology is now widely accepted and it meets all the industry codes, standards and recommended practices.
All work is completed only after thorough professional engineering evaluations are performed and are accomplished with very conservative safety factors built in.
Calculations are in accordance with:
- Local codes and practices
- Knowledge of the tank’s original construction
- American Petroleum Institute tank construction standards and details
- Local wind conditions
- Tank Stress
- Maximum air bag pressure
- Calculated floor sag
- Required number of perimeter supports
- Maximum floor stress at center of floor
- Foundation load
- Proven ground bearing pressure and shear strength
- Minimum number of tank supports
- Wind velocity
- Skidding
- Tank overturning
- Storm Anchors
- May be required when increasing the lowest wind velocity
