CalRes
CalRes, Life Cycle Cost Calculation Software for storage tanks
A user friendly software program which provides a comparison of investment and life cycle costs for storage tanks.
The Calres software has been developed to facilitate a quick comparison of the initial investment cost for high capacity storage tanks fabricated from different materials, including coated carbon steel and stainless steel grades. The program also allows you to compute a detailed cost analysis of the maintenance costs over the expected life of the equipment.
The Calres software is based on the American standard API 650 and the French CODRES code for the wall thickness calculation. These standards, developed for the storage of oil based products, may be used for storage tanks for other products or for other industries. The development of this software has been carried out with the technical assistance and the contribution of companies specializing in each stage of tank manufacture.
The configuration studied for the cost comparison program represents a vertical, cylindrical tank, with a flat bottom and a self-supporting cone or dome roof.
This program will show that in many cases the use of stainless steels for building storage tanks may constitute a very competitive solution when compared to building tanks in carbon steels which require protection by painting the external surface and coating the internal surface.
Due to the increased mechanical properties of duplex stainless steel grades, it is possible to reduce the tank wall thicknesses and consequently obtain important cost savings related to material, welding and erection costs.

Disclaimer
The results of the cost analysis shown in the Calres software demo version are provided for information only and a complete simulation can be provided upon request.
Industeel is not responsible for decisions or costs related to the applicability of codes, materials, or fabrication processes for specific service conditions, unless they have been confirmed in writing by Industeel in conjunction with a specific material order.
Calres software is an interactive program which consists of a Main Screen for the input of basic tank design parameters, and several other screens for secondary parameters and calculation results.
The Main Input Screen contains the data related to the characteristics of the tank, the stored fluid and the candidate materials. Other secondary parameters may be adjusted by the user. Some examples are : plate dimensions, welding materials, external and internal coatings and labor costs. As soon as the user has introduced all data corresponding to their needs, the results of the cost analysis appear on the Result Screens in tabular or graphic form.
Total Investment Cost and Life Cycle Cost may be visualized instantaneously, and the user will have access to detailed cost data concerning all manufacturing and maintenance operations over the expected tank life.The user will also have access to information related to the calculated wall thicknesses and the calculated weight for each part of the tank.
The complete master version of Calres software is an Excel-based tool which allows most of the parameters to be varied using input data boxes. This allows the user to adjust the required data to their needs.
The continuation of this program is a demo version of Calres software. This version allows you to simulate a cost analysis which provides a cost comparison of four materials by using some predefined parameters. You may select the required parameters by clicking on the desired data Icons.
We invite you to contact Industeel if you wish a complete cost analysis, including your own parameters, for any stainless steel or carbon steel grades. The comparison will be run using the master Excel-based Calres software. Our sales agencies will provide you this cost analysis free of charge.
