Why choose Bunney’s
-
End-to-end delivery: Concept, engineering, fabrication, civil works, erection, testing, and turnover.
-
Compliance first: Built and inspected to applicable standards (e.g., API 650/620/12F, API 653, NFPA 30) and aligned with federal, state, and local requirements, including SPCC planning.
-
Service life focus: Coatings, cathodic protection, floating-roof seal upgrades, and reliable venting/overfill protection.
-
Arizona-ready details: Heat-rated seals, UV-resistant components, dust-tolerant breathers, and stormwater/containment solutions for intense rain events.
Tank options & specifications
-
Fixed-roof (FR) tanks: Cost-effective for low- to moderate-vapor stocks; available in welded or bolted configurations with internal liners and inert gas options.
-
Internal floating-roof (IFR) tanks: Minimize vapor space and product loss; primary/secondary rim seals and shoe seals for high efficiency.
-
External floating-roof (EFR) tanks: Field-erected for large volumes; selectable roof drains, anti-rotation, and weather-tight seal systems.
-
Shop-fabricated & bullet-style horizontals: For smaller footprints, truck-deliverable with rapid set and tie-in.
-
Foundations & containment: Ringwalls, slabs, geosynthetic liners, clay cores, and coated concrete sumps sized for required containment volumes.
Safety & environmental controls
-
Vapor management: Conservation vents, P/V valves, ER/VRC integration, and domes over EFRs where appropriate.
-
Fire & overfill protection: Foam chambers or pourers, foam dams, level alarms, automatic shutoff, and emergency venting.
-
Corrosion mitigation: System-matched primers/topcoats, internal linings, and impressed-current or galvanic anodes with test stations.
-
SPCC & stormwater: Containment sizing, drainage controls, and maintainable outfalls to support permit conditions.
Lifecycle services
-
API-653 inspections: Out-of-service and in-service exams, UT thickness surveys, MFL floor scans, settlement monitoring, and fitness-for-service.
-
Repairs & upgrades: Floor patching/replacements, shell inserts, nozzle add-ons, floating-roof retrofits, seal changes, and nozzle/stair upgrades.
-
Coatings & linings: Surface prep, lining selection, holiday testing, and cure verification.
-
O&M programs: Routine walkdowns, emissions-reduction tune-ups, cathodic protection surveys, and records management.
Our build process
-
Site walk & basis of design → product data, capacity, emissions targets, and operability.
-
Engineering → tank, foundation, containment, and tie-ins.
-
Civil & erection → foundations, shell/floor/roof, appurtenances, NDE.
-
Commissioning → hydrotest, calibration, safety device checks, and O&M turnover.

FAQs
Which is better for crude—fixed roof or floating roof?
For higher-vapor crude or when minimizing product loss is a priority, IFR/EFR tanks reduce emissions and heel losses. Fixed roofs fit lower-vapor stocks or smaller capacities.
Do you handle SPCC and permitting support?
Yes. We size secondary containment, provide drawings and calculations, and coordinate with your environmental team to align with SPCC and local requirements.
How often should a crude tank be inspected?
Perform routine in-service checks annually, with formal API-653 external inspections at code intervals and internal inspections based on corrosion history and service.
Can you upgrade an existing tank instead of replacing it?
Often. Floor plate replacements, shell inserts, new nozzles, IFR retrofits, and coating/lining work can extend service life and cut downtime versus full replacement.
What drives project timeline the most?
Lead times for steel and seals, permit durations, and site civil work. Early design decisions on roof type, foundation, and containment accelerate procurement and construction.
