TANK是由美国COADE公司根据最新的API（美国石油学会）650 和API653标准，基于PC兼容机进行设计分析储油罐的综合工程设计软件。
TANK为用户提供了设计、分析、评估等多种功能，它采用变点法即一步法或API650中定义的方法计算壳体、壁厚和许可液位。TANK还能完成承受地震和风载荷计算，内部压力计算，管嘴柔性及载荷极限计算，抗风圈测定，极限壁厚及残余裕度许可计算，壳体固定分析，罐底盘最小壁厚计算。并能采用Brownell & Young中的推荐方法设计及分析支撑圆锥体罐顶。
TANK提供了完善的功能，能节省您的计算时间，COADE公司并提供及时，一流的技术支持。
TANK一次依靠计算机完成的大量的工程计算任务是人工常规工作所无法比拟的。您通过菜单驱动滚动条和选择界面，随时可选出您所需要的合理的选项，并为每个数据域提供与上下文有关的即时的在线帮助。
TANK提供许多的工具，包括文件管理，如文件的调用、拷贝、删除，尤其重要的是保存那些各种各样的客户或项目的数据文件。还有全面的控制选项，从计算到屏幕颜色，使您能够制定出您自己喜欢的TANK环境。并提供一些标准单位制文件，但是不管您是用哪种单位制系统工作，TANK都能与CAESARII中相同的单位制管理系统相兼容，您也可将已存在的工作完全换成一套新的单位制。

TANK is a comprehensive， easy-to-use software package for the design， analysis and evaluation of oil storage tanks. It provides users with quick and accurate designs for new tanks and evaluation of existing tanks.

Data Collection
The menu-driven interface of TANK allows for the quick definition of input and functions for the accurate analysis of oil storage tanks to American Petroleum Institute (API) standards.
 
Increased flexibility is provided by allowing users to select any unit combination for analyses or to produce reports. In addition， unit files are completely user-definable so engineers are not bound by program default settings. Even existing jobs can be converted to any existing unit format.

User Interface
The user interface in TANK presents only what is needed at each point of information gathering. Therefore， users are not burdened with ‘out-of-sequence’ requirements for information required for analysis. You are asked for what is needed， when it is
needed.

Analysis Options and Codes 
TANK performs calculations in accordance with the latest API Standards 650 and 653. Analysis can also take into account wind， seismic and settlement conditions plus calculate air venting requirements to API 2000 Section 4.3.

Output and Reports
After completing an analysis， users can view the results in a tabular report or as a graphic diagram with associated data. For convenience in verifying the results， the output reports reference code sections used where applicable.

Material Databases
TANK has many databases integral to the package which make it easy to select standard data for accurate analysis. A number of US and international structural steel databases are provided. API materials are available from 1998 through 2008.

Quick， Context-sensitive Help
TANK’s context-sensitive help provides instant technical assistance at the point of input. Pertinent information is presented relative to each selected item， including code references and technical advice. Built-in search makes for rapid navigation.
