Steel Structure Design for Oil & Gas Plants | KHAAS
Steel structures in oil and gas facilities support piping, equipment and access systems while transferring loads safely to the foundations. Their design must coordinate structural behavior with the plant layout, operating conditions and maintenance requirements.
KHAAS Design & Engineering provides steel structure analysis and detailing for pipe racks, equipment platforms, skid frames and associated industrial supports. Each project is developed against an agreed design basis and the applicable project requirements.
Steel structures for oil and gas plants
Typical structures include pipe racks, equipment support frames, access platforms, walkways, stairs and modular package frames. Their geometry is shaped by process routing, equipment clearances, future expansion and the construction sequence.
Bracing and support arrangements should provide clear load paths while preserving the space needed for plant operation and maintenance.
Steel structure design methodology
Review layout drawings, equipment data, piping loads, site conditions and project specifications.
Establish the structural system, materials, support assumptions and governing design criteria.
Assess the applicable gravity, operating, thermal, wind, seismic and temporary load cases.
Check member strength, overall stability, serviceability and connections.
Coordinate anchor layouts and reactions with the foundation designer.
Prepare drawings and resolve multidisciplinary review comments.
The adopted structural code and edition depend on the project jurisdiction and contract requirements; they are recorded in the design basis.
Pipe rack and equipment-support considerations
Pipe racks receive vertical weights as well as forces from friction, thermal restraint and wind on the supported systems. Coordinate guide, anchor and sliding-support assumptions with the piping stress team.
Equipment platforms need defined operating and maintenance loads. Rotating equipment may require vibration assessment using vendor data; support stiffness and connection behavior can influence the response.
Connections, durability and buildability
Bolted and welded connections must transfer the forces assumed in the global model. Account for eccentricity, local member effects and practical access for fabrication and erection.
Project requirements may also address corrosion protection, drainage, fire protection, inspection and replacement access. Coordinate these details with the owner and relevant specialists.

Industrial steel design FAQs
Can an existing pipe rack carry additional piping?
Its capacity must be reviewed using the as-built condition, original design information, existing loads and proposed additions. Connection and foundation capacity also need consideration.
What information is needed for a quotation?
Provide the layout, site location, supported equipment and piping data, applicable specifications, existing drawings where relevant and the required deliverables.
