Core Values of Octave Aspect Tank

Six key benefits of using Octave Aspect Tank in oil and gas storage tank design for EPC projects Compliance with International API & EN Standards

Compliance with International API & EN Standards

Octave Aspect Tank performs calculations based on the latest API standards, including API 579 (Fitness-For-Service), API 620 (Design of Low-Pressure Storage Tanks), API 650 (Welded Steel Tanks for Oil Storage), and API 653 (Tank Inspection, Repair, Alteration, and Reconstruction). Additionally, the software complies with European standard EN 14015, ensuring adherence to international requirements for export-oriented projects.

Intuitive Interface with Context-Based Data Entry

Aspect Tank’s menu interface allows rapid definition of input data and access to analysis functions. Only relevant information is displayed at each stage, eliminating requests for out-of-sequence data. You are only prompted for necessary information at the right time. A context-sensitive help system provides real-time technical support during data entry, including standard references and engineering guidance.

Flexible Unit Systems

Aspect Tank offers complete flexibility in measurement units — enabling selection of any combination of units for analysis or report generation. Unit definitions are fully customizable, so engineers are not restricted to default settings. Existing project files can also be converted to any available unit format.

Extensive Material Database

Aspect Tank integrates a comprehensive built-in material database to facilitate accurate analysis and material selection. It includes structural steel specifications from US and international standards, along with API-compliant materials. Both carbon steel and stainless steel grades are supported.

Advanced Multi-Load Analysis

Aspect Tank performs analysis under wind, seismic, and foundation settlement loads, while also calculating nozzle loads and flexibilities. It further computes shell course thickness, roof thickness (for cone, dome, and umbrella designs), anchoring requirements, and allowable liquid heights.

Visual Reporting & 3D Graphics

Upon completion of analysis, results can be viewed in tabular reports or graphical formats with supporting data. Output reports reference the specific standards applied for easy verification. The software features interactive 3D visualization and drawing view modes, and supports report export to Word, PDF, and other formats. It also displays underlying formulas and calculation steps, allowing users to independently verify accuracy.

Technical Features of Octave Aspect Tank

Key analysis and design capabilities integrated into the software

Steel Oil Storage Tank Design

Aspect Tank supports comprehensive design of steel oil storage tanks, including calculation of shell course thickness, design of cone, dome, and umbrella roofs, and verification of allowable liquid heights.

Wind Load & Anchorage Analysis

The software calculates wind loads acting on storage tanks and designs corresponding anchorage systems. Analysis results ensure tank stability under high wind conditions in compliance with applicable design standards.

Seismic Analysis

Aspect Tank conducts seismic analysis for storage tanks, evaluates structural resistance to earthquake loads, and proposes appropriate reinforcement measures — a critical feature for projects in seismically active regions.

Foundation Settlement Analysis

The software evaluates the impact of soil settlement on tank structures and recommends foundation improvement solutions, ensuring long-term structural integrity and operational safety.

Nozzle Load & Flexibility Analysis

Aspect Tank calculates loads and flexibilities for tank nozzles — a key factor in ensuring that piping connections do not induce excessive stress on the tank shell.
Venting Calculation

Ventilation Calculation per API 2000

Aspect Tank determines ventilation requirements in accordance with API 2000 Section 4.3, ensuring tanks are designed with appropriate venting systems to prevent dangerous overpressure or vacuum conditions during operation.
