You win the fabrication and erection jobs. We back you up on the engineering — without the overhead of a big consultancy.
Freelance structure means no layers of project managers. You pay for engineering hours, not corporate overhead.
Direct communication with the engineer doing the work. Typical calculation packages delivered within days, not weeks.
Fluent in English, experienced with Indonesian and international project documentation and client reviews.
Per tank, per package, or monthly retainer for ongoing projects. Whatever fits your workflow.
Yes. All work is prepared to the applicable code (API 650, API 620, etc.) with full traceability of inputs, methods, and software/spreadsheets used, so it can go through owner or TPI review with confidence.
Both. Most clients prefer a fixed price per tank package; larger contractors sometimes retain us monthly for rolling projects.
Typically: tank data sheet or client specification, design conditions, and any site-specific requirements (wind, seismic zone). If you don't have these, we'll help you build the input basis.
Yes — API 653 covers repair, alteration, reconstruction, and re-rating of existing tanks. We prepare the calculations and drawings required for those scopes too.
