TANK is a comprehensive, easy-to-use software program for the design, analysis and evaluation of welded steel oil storage tanks according to the latest American Petroleum Institute (API) Standards 650 and 653. It provides owners, operators and engineering firms with quick and comprehensive designs for new tank construction and evaluation of existing tanks.

TANK offers design and analysis using the variable point, one-foot and Appendix A thickness methods and includes all the tools to quickly and accurately analyze and design supported cone roofs, evaluate bottom plate minimum thickness and shell settlement and determine seismic requirements including anchorage design. It evaluates wind stability; wind girder requirements; internal pressure and allowable fluid heights and designs anchorage-based wind, pressure and seismic conditions. TANK includes extensive built-in materials and structural steel plus digitized curves for seismic and nozzle analysis.
