AMETANK 2025 V18.9.22 is a highly specialized, industry-leading software application dedicated to the design, analysis, and integrity assessment of aboveground, welded steel storage tanks used in the oil & gas, petrochemical, water, and power industries. Developed in strict accordance with the latest editions of API Standard 650 (Welded Tanks for Oil Storage), API Standard 653 (Tank Inspection, Repair, Alteration, and Reconstruction), and relevant sections of the ASME Boiler and Pressure Vessel Code, it serves as an indispensable digital engineering partner for tank designers, integrity engineers, and inspectors worldwide.

Core Philosophy: Ensuring Safety & Compliance Through Automation
The software's primary purpose is to automate the complex, repetitive, and critical calculations mandated by industry codes. It eliminates manual calculation errors, ensures all design assumptions and safety factors are correctly applied, and generates the comprehensive documentation required for project approval, regulatory compliance, and safe long-term operation.

Key Features & Capabilities:

1. Comprehensive New Tank Design (API 650)

• Shell Course Design: Automatically calculates the required thickness for each shell course based on product-specific gravity, design liquid level, and material allowances, optimizing material usage while ensuring structural integrity.

• Roof & Bottom Design: Designs self-supported cone roofs, supported cone roofs, and flat bottoms, including annular plate rings. Performs stability checks for external pressure (vacuum) on frangible roof joints.

• Wind & Seismic Analysis: Performs detailed calculations for wind girder requirements (intermediate and top) and rigorous seismic analysis per API 650 Appendix E, evaluating shell overturning stability, anchorage requirements, and hydrodynamic hoop stresses.

2. Tank Integrity & Fitness-For-Service Assessment (API 653)
This is critical for the life-cycle management of existing assets.

• Minimum Thickness Evaluation: Determines the retirement thickness for shell and bottom plates based on current inspection data (ultrasonic thickness readings) and future corrosion allowances.

• Maximum Fill Height Calculation: Calculates the safe maximum liquid level for tanks with corroded or repaired sections.

• Shell Settlement Analysis: Evaluates the severity and impact of differential tank foundation settlement (edge settlement, bottom settlement) on structural integrity.
