We build solutions, systems, workflows, engineering tools and complete calculation packages.
Twelve years inside engineering firms — pressure equipment, heat exchangers, tanks, skid and piping packages, and the people who fabricate them. That is where every one of these came from.
Srutheesh Saseendran — founder, Zb International.
Where this comes from
01Process equipment first, designed with my own hands — pressure vessels, shell-and-tube and fin-tube exchangers, storage tanks — by hand calculation, in Excel and in the software, to ASME, TEMA and API. Thailand, Vietnam, China, India. An ASME designer with an MBA in finance: the person who argues the calculation and the contract in the same meeting.
Then the work that stretches a designer. A company’s first cryogenic tank, developed from nothing to approval. Hydrogen-storage R&D for the automotive industry that ended in a granted patent with my name on it. Gas and steam turbine plants and their piping. Skid and module packages engineered to arrive plug-and-play. Advisory seats on some of the largest projects those companies ran — and a vendor in Vietnam qualified for a commodity they had never held, validated by independent inspection.
I do my best work on problems that reward patience. The failure nobody examined closely. The assumption three reviews carried forward unchecked.
Why workflow systems
Because I kept building them anyway. Spreadsheet tools for the same problem a fourth time. Scripts to stop a number being retyped. At some point the workarounds stopped being workarounds and became the work itself: complete systems, shaped to one firm’s way of working.
How we work
The way engineers work. Each company’s challenge gets a proper problem definition first. From the definition comes the workflow logic; from the logic, a working model — designed, then improved, by proper engineering method. That is why every system we deliver is a crafted piece of engineering. And we say what is not finished before anyone asks — a page of this site is given over to testing whether we do what we say.
