TRI*TANK650™

TRI*TANK650™ designs or re-rates cylindrical tanks with sloped or flat-bottoms in accordance with API 650 Standard, "Welded Steel Tanks for Oil Storage", 8th. 9th. or 10th. Editions. Wind and seismic loads can be applied in the re-rating or design modes, and the allowable criteria of several different wind and seismic standards can be applied.

Applications
· Provides technical compliance and documentation for regulatory authorities
· Designs new tanks and rerates existing tanks
· Calculates shell plate thickness and weights.

The Advantages & Benefits
The advantages of using these programs include:
· Saves time and cost in meeting technical compliance and documentation for regulatory authorities
· The reliability of design calculations is greatly improved
· Assists in standardization of the design process and procedures through the use of a proven engineered template approach to the design   process
· Decreases the amount of time required for tank design by adding "what-if" design and re-rating capability
· Enhances productivity by evaluating alternative tank designs prior to fabrication.

Output · Shows API equations with variable defined and substituted for engineering verification · A summary page for each major set of calculations is presented showing calculated   values of shell design, wind loads etc. · Find feature allows the user to go to desired location(s) · All Output reports can be browsed, printed and exported to HTML or TXT files.
