API-650 Tank Design

Design aboveground storage tanks in accordance with API-650 standards to ensure structural integrity and code compliance.

Service Overview

At Engineering Design Services, our tank design services provide clients with safe, reliable, and code-compliant storage solutions for aboveground storage tanks. We take a detail-oriented engineering approach to designing tanks that meet operational demands while aligning with industry standards and long-term performance expectations.


Our team works closely with clients to understand product storage requirements, site conditions, and operational constraints. From initial concept through detailed design, we develop tank systems that account for structural integrity, material compatibility, environmental conditions, and constructability. Whether designing new tanks or supporting modifications to existing assets, we ensure every design is practical, efficient, and compliant with API-650 requirements.


By combining mechanical design expertise, structural analysis, and field-informed engineering practices, we deliver tank designs that enhance safety, extend service life, and support efficient operations. From petrochemical storage to emerging energy infrastructure, our solutions are built for durability and performance.


Whether supporting new facility development, tank farm expansions, or replacement projects, our team delivers tank designs tailored to your operational needs and regulatory requirements.

Engineering Challenge We Solve

Designing aboveground storage tanks involves complex considerations that impact safety, longevity, and compliance. Our approach addresses these challenges by:

  • Ensuring Structural Integrity: Designing tanks to withstand internal pressures, wind loads, seismic conditions, and settlement.

  • Maintaining Code Compliance: Aligning designs with API 650 and applicable regulatory requirements.

  • Preventing Material Failures: Selecting appropriate materials to mitigate corrosion, cracking, and environmental degradation.

  • Optimizing Tank Performance: Designing for efficient storage, drainage, and maintenance access.

  • Supporting Constructability: Delivering designs that can be built efficiently in the field while minimizing risk and cost.
