Multidisciplinary Engineering Consultancy

A&N Integrated Consultancy Services provides comprehensive engineering and technical consultancy across Process, Mechanical, Piping, Electrical, Instrumentation & Control. We support projects across the Oil & Gas, Refining, Petrochemical, Chemical, Energy, and Utilities sectors, providing practical engineering solutions from concept and feasibility through detailed engineering.

Our approach combines sound engineering principles, practical industry experience, and effective multidisciplinary coordination. We focus on solutions that consider not only technical requirements, but also safety, reliability, operability, maintainability, and constructability throughout the project lifecycle.

Our Core Engineering Scope

We specialize in delivering technical precision, robust calculations, and construction-ready deliverables for complex brownfield and greenfield projects.

Process Design Basis & Simulations
PFDs & P&ID Development
Equipment Sizing & Datasheets
Piping Stress & Flexibility Analysis
Electrical Load Assessment & SLDs
Control Philosophy & Cause & Effect

Our multidisciplinary team prepares comprehensive engineering packages, including detailed 2D/3D design layouts, equipment specifications, material take-offs (MTOs), vendor drawing reviews, and constructability reviews to ensure seamless site execution and commissioning.

Process Engineering

From process concept to practical design. We deliver process simulation, CFD analysis, equipment sizing, and hydraulic calculations.

Mechanical & Piping

Reliable equipment and practical piping solutions. We handle static/rotating equipment, material selection, and stress analysis.

Discipline-Specific Engineering Deliverables

Beyond process engineering, our consultancy covers specialized engineering domains essential for comprehensive plant design and execution:

Process Engineering: Process Flow Diagrams (PFDs), P&ID development & review, utility system design, line sizing, Line Lists, Tie-in Lists, and brownfield/revamp studies.
Mechanical & Piping Engineering: Equipment specifications, Material Requisitions (MR), Technical Bid Analysis (TBA), Piping Material Specifications (PMS), pipe flexibility and stress analysis, and FEA Analysis.
Electrical Engineering: Electrical design basis, power distribution systems, Single Line Diagrams (SLDs), motor/MCC/VFD requirements, cable sizing and schedules, earthing & grounding, and lightning protection.
Instrumentation & Control: Field instrumentation, Instrument Index, I/O requirements, DCS/PLC/SIS interfaces, control philosophy, Cause & Effect development, ESD system engineering, and Fire & Gas system requirements.

Through this rigorous multidisciplinary engineering approach, we help you ensure technical precision, seamless coordination, and reliable project delivery.
