Atmospheric Storage Tanks
Large-diameter atmospheric storage tanks to API 650, API 620, AWWA D100, and related international standards.
Atmospheric storage tank farm — petroleum terminal
Overview
Basiia provides engineering, procurement, and construction management for large-diameter atmospheric and low-pressure storage tanks across the full range of applicable standards — API 650 for petroleum and chemical storage, API 620 for low-pressure and cryogenic service, and AWWA D100 for potable and industrial water storage. Our scope covers tank design, foundation specification, appurtenances, roof systems, and full documentation packages for regulatory approval and third-party certification.
Typical Applications
- Crude oil, condensate, and refined product storage (API 650)
- Low-pressure and cryogenic liquid storage (API 620)
- Potable water, fire water, and municipal water storage (AWWA D100)
- Chemical and petrochemical bulk liquid storage
- Produced water storage and handling
- Industrial process water and wastewater holding tanks
- LNG and ammonia storage (API 620 low-pressure)
- Terminal and distribution hub tankage
Key Features
Engineered for Performance
API 650 — Petroleum & Chemical Tanks
Complete tank design to API 650 for atmospheric storage of petroleum, chemicals, and water. Covers shell, roof, bottom, nozzles, and appurtenances with full calculation packages and material traceability.
API 620 — Low-Pressure & Cryogenic Tanks
Engineering and procurement for large welded low-pressure storage tanks to API 620, including cryogenic and refrigerated liquid service with appropriate material selection and insulation systems.
AWWA D100 — Water Storage Tanks
Welded carbon steel tanks to AWWA D100 for potable water, fire suppression, and industrial water storage — including NSF/ANSI 61 lining systems where potable water contact is required.
Roof Type Selection
Fixed cone, external floating roof (EFR), and internal floating roof (IFR) configurations engineered to product vapour pressure, site conditions, and environmental requirements.
Foundation Design Coordination
Foundation loading specifications and coordination with civil engineers for ring wall, mat, and pile foundation designs across all tank standards.
Inspection, Testing & Certification
Hydrostatic testing, weld inspection, NDE, and third-party verification in accordance with the applicable standard (API 650, API 620, or AWWA D100) and client requirements.
