Storage Tanks Design & Integration
Large vertical storage tanks are non-standard engineering structures custom-designed per project conditions, international standards and actual construction requirements.We prioritize safety, compliance, durability and long-term reliability over cost reduction, bridging technical theory and practical industrial construction.
Design Philosophy for Large Vertical Storage Tanks
Large vertical storage tanks are engineering structures, not standardized products.
Our design philosophy focuses on safety, compliance, durability, and constructability, ensuring that every tank performs reliably throughout its service life.
Each tank is designed based on:
- Project-specific operating conditions
- Applicable international design standards
- Actual construction and installation methods
A high-caliber design department must bridge the gap between “technical theory” and “industrial reality.” We view large vertical storage tanks as high-risk engineering structures, not off-the-shelf products.
Our design philosophy is grounded in a core principle: engineering safety and long-term reliability must always take precedence over cost-cutting.
Applicable Design Codes and Standards
We design and engineer to the world’s most stringent codes, ensuring that your infrastructure meets both international quality benchmarks and local regulatory requirements, including but not limited to:
- API 650 – Welded Tanks for Oil Storage
- EN 14015 – Aboveground Storage Tanks
- GB 50341 – Chinese Code for Vertical Cylindrical Steel Tanks
Design standards are selected based on:
- Project location: The design is tailored to the local conditions, considering geological, climatic, seismic, and environmental factors to ensure structural suitability.
- Stored medium: The design optimizes corrosion protection, sealing, and pressure-bearing based on the physical and chemical properties of stored materials, including composition, corrosion resistance, temperature, pressure, flammability, explosiveness, and volatility.
- Technical Solutions and Customization Requirements: We develop customized storage tank design solutions tailored to the specific requirements of each project, including overall process layout, integration with supporting equipment, dimensional specifications, and functional configurations.
The storage tank designs we provide not only ensure high safety, reliability, and adaptability, but also fully address the specific requirements of various projects.
Design Inputs and Engineering Parameters
Accurate tank design begins with clearly defined technical inputs. Key design parameters include:
- Tank capacity, diameter, and height
- Stored liquid properties and operating temperature
- Design pressure and vacuum conditions
- Wind load, seismic load, and snow load
- Corrosion allowance and service environment
- Required service life and inspection class
These parameters form the basis for all structural calculations and material selection.
Structural Design and Thickness Calculation
The wall thickness of each part of the storage tank (including the tank wall, tank bottom and tank top) has been precisely calculated through detailed engineering analysis, and the corresponding design standards have been used to select the appropriate thickness.
Our structural design process includes:
- Load Analysis and Structural Assessment
- Material selection and thickness calculation
- Base plate and support system design
- Design of reinforcing elements and supporting structures
- Seismic verification and structural reinforcement design
- Corrosion allowance check and wall thickness optimization
- Overall storage tank stability and anti-overturning calculation
All thickness values are verified to meet or exceed minimum code requirements.
Every plate thickness is defined by calculation, not assumption.
Roof, Bottom, and Accessories Design
Based on the actual requirements of the project, we have carried out specialized and customized design and integration work for different types and operating conditions of storage tank systems, ensuring that the storage tank systems can fully meet the project expectations in terms of safety, practicality, economy, and maintainability, and can also meet the requirements for medium storage, transportation, and related processes:
Roof Systems
- Fixed roof
- External floating roof
- Internal floating ro
Bottom Structure
- Flat bottom
- Annular plate reinforcement
- Leak detection and drainage systems
Accessories and Appurtenances
- Manholes and nozzles
- Vents and safety valves
- Ladders, stairways, and platforms
All components are designed as an integrated system to ensure safety, accessibility, and ease of maintenance. All components are designed as an integrated system to ensure safety, operability and ease of maintenance.
