API 650 / API 653 Tank Design & Compliance

At Trang Imagineering, we deliver certified mechanical engineering solutions for bulk storage tanks across mining, industrial, and agricultural sectors. With deep experience in API 650 and API 653 standards, we ensure that new tanks are compliant and efficient — and that existing tanks remain safe, serviceable, and fit for purpose.

We work with asset owners, contractors, fabricators, and maintenance teams to support every stage of tank lifecycle — from design and documentation through to inspection, remediation, and recommissioning. Whether you're constructing a new diesel or process water tank, or extending the life of aging infrastructure, we offer smart, compliant solutions grounded in real-world experience.

Our Tank Services Include:

  • New API 650 tank design and certification for welded steel tanks used in fuel, chemical, and water storage

  • Integrity assessments and engineering inspection reports for in-service tanks

  • API 653 remediation designs, including nozzle replacement, floor repair, roof upgrades, annular plate assessment, and more

  • Development of hydrostatic test plans, repair procedures, and engineering documentation to support shutdown scopes

  • Interface design for foundations, pipework, and access structures, including collaboration with site-based structural or civil teams

Why Choose Trang for API650 / API653 Work?

We’re not just paper pushers. Trang Imagineering's mechanical focus means we understand the practical constraints of working on operational sites: tight shutdowns, limited access, and site-specific logistics. Our designs are buildable, certifiable, and tailored for fast mobilisation.

We’ve delivered tank solutions on mine sites, regional fuel depots, and ag-chemical facilities: often under pressure, and always with compliance in mind. Whether you're building from the ground up or need urgent remediation support, we’ll help you get the job done, without over-engineering or delay.
