Key Responsibilities

Position Summary

Responsible for providing comprehensive Instrumentation & Controls (I&C) engineering support for gas pipeline projects during pre-bid, proposal development, and detailed engineering stages. The role ensures technical accuracy, compliance with client specifications, and optimized design solutions aligned with EPC project requirements.

Key Responsibilities

1. Pre-Bid / Proposal Engineering

• Review client tender documents, specifications, data sheets, and project scope for I&C requirements.

• Prepare preliminary I&C design basis, equipment lists, and bill of quantities (BOQ) for cost estimation.

• Develop instrument data sheets and preliminary sizing for key field instruments (pressure/temperature transmitters, flow meters, analyzers, RTUs, safety systems, etc.).

• Support development of technical clarifications, deviations, and queries during bidding.

• Coordinate with proposal, procurement, mechanical, electrical, and pipeline engineering teams to develop optimized solutions.

• Provide inputs for proposal drawings (Hook-ups, typical layouts, control philosophy, P&IDs support, I/O summary).

2\. Detail Engineering Support

• Finalize design basis, instrument index, I/O lists, and instrument BOM.
• Perform instrument sizing calculations (control valves, ESD valves, flow elements).
• Prepare detailed engineering deliverables:
  • Instrument datasheets
  • Hook-up drawings
  • Cable schedules
  • Loop diagrams
  • Junction box layouts
  • Control room layouts
  • Panel specifications (RTU/PLC/SCADA cabinets)
• Develop control narratives, cause & effect matrices, shutdown logic, and alarm philosophy.
• Review and validate P&IDs, pipeline process drawings, and ensure alignment with control and safety systems.
• Support hydraulic, SCADA, and telecom interface requirements for long-distance pipeline systems.

3\. Vendor & Procurement Support

• Prepare technical specifications for instruments, analyzers, RTUs, and control systems.
• Evaluate vendor offers, review technical documents, and participate in TBE (Technical Bid Evaluation).
• Coordinate FAT, SAT, inspection, and quality checks for I&C equipment.

4\. Project Execution & Coordination

• Interface with mechanical, electrical, civil, process, and SCADA teams for integrated engineering deliverables.
• Provide technical support for construction, commissioning, and site queries.
• Ensure compliance with relevant standards: ASME, API, ISA, IEC, OISD, PNGRB, and client-specific standards.

5\. Documentation & Quality

• Maintain updated instrument index, discipline registers, and engineering trackers.
• Ensure all deliverables meet project quality, schedule, and cost requirements.
• Support preparation of final documentation, O&M manuals, and as-built engineering.
