The American Petroleum Institute addresses wind explicitly for large storage tanks. API 650’s Annex F covers wind overturning checks, and the new editions incorporate ASCE 7’s detailed pressure coefficients for cylindrical shells.
Many engineering firms provide access to PIP and ASCE standards through internal document portals.
Several consulting firms (e.g., RWDI, CPP Wind, Boundary Layer Wind Tunnel Laboratory) specialize in industrial wind engineering. Testing costs typically range from $30,000–$150,000—often justified for multi-billion-dollar facilities. Several consulting firms (e
For structural engineers, designers, and safety professionals, accessing the right technical resources is paramount. If you are searching for a you are likely looking for the industry-standard guidelines that bridge the gap between general building codes and the specific realities of industrial infrastructure.
Wind loads on spherical vessels depend on Reynolds number. For large spheres (>10 m diameter), the drag coefficient may be lower, but localized suctions can affect external insulation and attached ladders/piping. If you are searching for a you are
In 2019, a Gulf Coast petrochemical facility conducted a recertification of its 1970s-era tank farm. Using the latest ASCE 7-16 and ATC 117 shielding factors, engineers discovered that two 100,000-barrel tanks were designed for 90 mph (3-second gust) but were now required to handle 115 mph due to updated climate data. Furthermore, interference effects from a new flare installed 150 feet away increased wind loads on the tank roof by 22%. Mitigation included stiffening rings and revised anchoring—a low-cost fix compared to a hurricane-season collapse.

These structures have unique aerodynamic profiles. For example, large-diameter storage tanks experience significant "uplift" forces on their roofs during high-wind events. Technical Standards and PDF Resources
