Oil & Gas
Equipment Design
The oil and gas sector demands process equipment that operates reliably under extreme pressures, temperatures, and corrosive conditions. Our engineering team designs pressure vessels, separators, heat exchangers, and reactors that meet stringent API and ASME codes — ensuring safety, longevity, and operational efficiency across upstream, midstream, and downstream applications.
Equipment Design Challenges
in Oil & Gas
High pressures, extreme temperatures, and corrosive media demand specialised engineering approaches.
Pressure Vessels & Separators
Oil and gas operations require vessels rated for extreme pressures. Our designs account for fatigue loading, cyclic operation, and multi-phase separation efficiency while meeting ASME Section VIII requirements.
Pipeline Heat Exchangers
Heat exchangers in pipeline applications must handle high fouling rates, thermal cycling, and corrosive fluids. We design for maximum heat transfer efficiency with minimal pressure drop.
ASME/API-Compliant Reactors
Reactor vessels for hydroprocessing, reforming, and catalytic operations require precise mechanical design, material selection for hydrogen service, and compliance with API 934 and ASME standards.
Corrosion & Erosion Management
Sour service, high-TAN crudes, and sand-laden fluids create severe corrosion and erosion challenges. Our material selection and wall-thickness calculations ensure reliable long-term operation.
Our 11-Step
Methodology
A structured methodology refined for the demanding requirements of oil and gas equipment.
Initial Consultation
Meet with the customer to define project objectives, operational challenges, and process-specific requirements through structured technical workshops.
We capture detailed process parameters such as operating pressures, temperatures, flow rates, fluid properties, and site constraints. This scoping phase produces a formal requirements specification that aligns all stakeholders on performance targets and project milestones.
Conceptual Design
Develop initial design concepts through feasibility studies, trade-off analyses, and preliminary process flow modelling.
Our engineers produce concept layouts, P&IDs, and high-level equipment sizing to compare competing approaches on cost, thermal efficiency, and footprint. Each concept is scored against weighted criteria so the preferred option is selected with full transparency.
Detailed Engineering Design
Create comprehensive 2D and 3D engineering drawings specifying dimensions, materials, tolerances, and manufacturing processes using industry-standard CAD platforms.
Deliverables include general arrangement drawings, fabrication details, bills of materials, and nozzle schedules. Every design decision is traceable to the requirements specification, ensuring the equipment will perform reliably across its full operating envelope.
Simulation & Analysis
Apply advanced computational techniques including CFD, FEA, and thermal-hydraulic modelling to validate design performance across the full range of operating conditions.
Simulations target critical phenomena such as stress distribution, fatigue life, heat transfer coefficients, and flow-induced vibration. Results are iterated until all safety margins and efficiency targets are met, reducing the need for costly physical rework.
Prototype Development
Build functional prototypes or scaled test rigs to validate design concepts, material compatibility, and manufacturing feasibility before committing to full-scale production.
Prototypes are subjected to controlled test campaigns covering performance, pressure integrity, and wear resistance. The empirical data collected is compared against simulation predictions to close any gaps and de-risk the final design.
Design Review
Conduct structured design reviews with multidisciplinary teams and client stakeholders to challenge assumptions, identify risks, and optimise the design.
Reviews follow a formal gate process covering HAZOP, constructability, and value engineering. Action items are tracked to closure, ensuring every aspect from weld accessibility to maintenance clearance is addressed before sign-off.
Compliance & Standards
Ensure every aspect of the design complies with applicable international codes, safety regulations, and environmental legislation relevant to the operating jurisdiction.
Our compliance engineers verify conformance against ASME, API, PED, ATEX, BSI, and EN standards through detailed code calculations and third-party review coordination. This proactive approach prevents costly non-conformances and accelerates certification timelines.
Documentation
Prepare a comprehensive documentation package including design basis memoranda, technical specifications, certified drawings, and calculation reports.
The package encompasses manufacturing procedure specifications, inspection and test plans, welding procedure qualifications, and quality control protocols. All documents are revision-controlled and delivered in formats ready for fabricator and third-party inspector use.
Design Validation
Perform factory acceptance testing and field validation to verify that equipment meets specified performance, durability, and reliability criteria under real-world conditions.
Tests include hydrostatic pressure trials, performance curve verification, vibration monitoring, and leak detection. Any deviations from design intent are root-caused and corrected, with results formally documented in a validation report.
Feedback & Iteration
Incorporate feedback from testing, validation, and client review to refine geometry, materials, or operating parameters for optimal performance.
Design iterations are tracked through a formal change management process that evaluates each modification for impact on cost, schedule, and compliance. This closed-loop approach ensures continuous improvement while maintaining full traceability of every change.
Finalisation
Finalise the design with formal customer approval, closing out all review actions and confirming every requirement has been verified before release to manufacturing.
The final deliverable set includes approved-for-construction drawings, material requisitions, and a design dossier. A structured handover meeting ensures the fabrication team has complete clarity on intent, tolerances, and quality expectations.
