How Gelan Reduces Storage Tank Project Risk
When selecting a storage tank supplier, buyers usually focus first on service fit, tank configuration, fabrication capability, inspection readiness, and delivery reliability. Gelan addresses these points early to help reduce avoidable project risk.
Avoid Mismatch Between Tank Design and Actual Service
If the tank does not match the actual storage medium, temperature, corrosion condition, or operating requirement, later changes, operational issues, and long-term reliability problems are more likely.
Gelan approach:
- Define tank design around actual storage medium and service condition
- Match material, roof design, and key inputs to project duty
- Review custom requirements early before fabrication starts
Get the Right Tank Configuration for Your Project Layout
If tank form, roof design, or overall configuration does not fit the project layout and operating requirement, the tank may create avoidable issues in installation, use, or later project coordination.
Gelan approach:
- Match vertical or horizontal form to layout and project condition
- Select fixed roof or floating roof design based on service requirement
- Review configuration together with tank duty, footprint, and operating need
Reduce Risk in Heavy-Duty Fabrication
If fabrication capability does not match project difficulty, thick-wall work, forming quality, weld integrity, and demanding service requirements can all become execution risks.
Gelan approach:
- Support thick-wall fabrication above 120 mm
- Support demanding pressure-related requirements above 100 MPa
- Apply controlled steel heating above 700°C for difficult forming work
- Support RT-based NDT for heavy sections above 60 mm
Prevent Delays Caused by Incomplete Inspection or Documentation
If inspection records, testing results, or fabrication documents are incomplete, project review, approval, shipment, and handover can all be delayed.
Gelan approach:
- Prepare inspection and testing records based on project requirement
- Support documentation aligned with API, ASME, and applicable project standards
- Organize document packages for review, delivery, and handover
Reduce Rework and Coordination Problems Later in the Project
If project requirements are not clarified early enough, later revisions in design, fabrication, shipment, or site coordination can create avoidable delay and extra cost.
Gelan approach:
- Clarify service duty, configuration, standard, and fabrication scope early
- Review fabrication and shipment arrangement against project conditions
- Support better alignment before production and delivery move forward

Related Equipment Around Storage Tanks
Storage tanks often work with other equipment for temperature control, separation, transfer, and downstream handling.
Shell & Tube Heat Exchangers
Separator Vessel / Drum
Often used where gas-liquid separation or buffer handling is needed around storage service.
Air Cooler
Often used where process liquid needs cooling before entering storage or downstream handling.
Column / Tower
Often used in refining, petrochemical, and chemical projects where storage tanks work alongside separation equipment.
FAQ About Storage Tank
How do I choose between a vertical storage tank and a horizontal storage tank?
A vertical storage tank is usually better for larger capacity and tighter footprint. A horizontal storage tank is more suitable when height is limited or layout is compact. The right choice should be based on storage volume, site conditions, and delivery arrangement. Gelan can review these inputs before confirming the tank form.
When should I use a fixed roof storage tank or a floating roof tank?
A fixed roof storage tank is commonly used for general liquid storage. A floating roof tank is more often used when vapor control and evaporation loss matter more. Some projects may also use an external floating roof tank or internal floating roof tank depending on the medium and operating condition.
What information should I send before asking for a quote?
For an oil storage tank or chemical storage tank, medium properties should be clarified early. Clear input helps reduce revisions and speeds up review.
Can one supplier support both oil storage tanks and chemical storage tanks?
Gelan supports both with project-based review instead of using one standard configuration for all duties.
Is API 650 always the right standard?
The right standard depends on service condition, pressure requirement, and engineering scope. It should be confirmed before detailed design starts.
What should I check when choosing a storage tank manufacturer?
Check service fit, tank configuration, fabrication capability, inspection records, and delivery support first. A qualified storage tank manufacturer should do more than quote a price. Gelan’s approach is to review these points early so the tank is customized around actual project requirements.
