TANK 2016 is now in production and will start shipping to customers soon. This is a very significant release of the software and includes a number of new features and code updates.
To start off, we received a new addendum to the API 650 code in January. It was addendum 2 to the twelfth edition. This new update contains significant mathematical changes that will produce different results than its predecessor. And of course, this means that the 2016 version of TANK will produce different results than the 2015 and previous versions. Here are a few notable changes:
Tables 5.21a and 5.21b – Uplift Loads
Uplift formulas revised and one formula removed.
W1, W2, and W3 definitions revised.
184.108.40.206 Top Wind Girder
Maximum tank diameter considered is 200 feet when computing the section modulus of the top roof/shell junction ring.
New requirement for computing the required moment of inertia for Wind Girders when the diameter is greater than 200 feet.
Maximum Design Pressure per F.4
The maximum design pressure Pmax is computed using new equations and depends on the type of roof the tank has.
There were, of course, many other changes to the code which are too numerous to list here.
Another major benefit is that we now include API 620 calculations. API 620 enables designers to use pressures up to 15 psig (1 atmosphere). In contrast, API 650 only allows design pressures up to 2.5 psig. Integrating a technically complex code like API 620 took quite a bit of time, as you might expect. Because the input is nearly identical for both, you can switch the design code and analyze each way for tanks that have low (less than or equal to 2.5 psig) design pressures.
1. You can represent the Nozzle Diameter Limit in the 3D model by right-clicking the mouse and selecting the “Diameter Limits” in the Visibility options. 2. You can sort the nozzle order in the Nozzle Schedule report by changing the options in the “Nozzle Sort Options” found in the Load Cases tab.

You can now export a TANK 3D image to SmartPlant 3D.
Go to the Tools tab, then the “Export to VUE Format” button. Browse to the file folder and the VUE destination folder, select the files you want to export, and then click the export button. You can now import those files into your SmartPlant 3D project.
