Structural design and optimisation

Steelwork designed to code and then refined by analysis, rather than sized by rule of thumb and left heavy.

Structural packages are checked by a Chartered Engineer with an MTech in Structural Engineering from IIT Guwahati and a PhD in Computational Mechanics. Technical leadership

Design, then optimise

Most structural steel in process plant is heavier than it needs to be. Not because engineers are careless, but because conservative sizing is fast and optimisation takes time that a project programme rarely allows.

The difference matters at fabrication. On a pipe rack or a skid frame, a disciplined optimisation pass typically removes weight without touching the utilisation limits — which shows up directly in steel tonnage, transport and erection cost. We treat that pass as part of the design, not as an extra.

Optimisation is bounded by what is sensible to fabricate. A section that saves 4% weight and requires a non-standard plate thickness is not a saving. We work to available section sizes and standard connection details unless there is a reason not to.

Weight is not the only objective. On offshore and lifting structures, fatigue life and inspection access often matter more than tonnage. We agree the optimisation objective before starting, not after.

What we design

Pipe racks and support structures

Multi-tier racks, sleeper ways, T-supports and stanchions, designed with the piping loads and thermal movement they actually carry rather than assumed nominal loads.

Equipment skids and frames

Package skids, compressor and pump bases, and modular frames — including lifting, transport and shipping load cases, which are frequently the governing condition.

Platforms, walkways and access steel

Operating and maintenance access designed around real-world reach and egress, not just a code-compliant minimum.

Lifting and handling structures

Padeyes, spreader frames, davits and lifting beams, assessed for the dynamic amplification and sling-angle cases that govern them.

Codes and standards

We work to the code the project is governed by rather than the one most convenient. Common bases include Eurocodes, AISC and the relevant Indian Standards for building and industrial steelwork, with offshore work assessed to recognised offshore structural practice.
