Lead Instrumentation & Control Engineer

Role Purpose

Instrumentation & Control Design

• Review FEED and EPC deliverables (P&IDs, C&E matrices, instrument index, loop diagrams, hook-ups).
• Finalize instrument sizing, specifications, and installation details as per ADNOC standards.
• Develop and validate control narratives and logic for IA/PA compressor operation and inter-platform coordination.
• Review layout drawings for instrument location and accessibility on existing decks.

Control System Integration (IA/PA Network)

• Integrate compressor UCP panels (e.g., Atlas Copco) with existing ADNOC systems:

• ABB DCS (800xA)

• Rockwell ESD

• Pms / Ecms

• Define signal mapping and communication protocols (Modbus RTU/TCP, Ethernet).
• Validate duty/standby logic and automatic start/stop sequences across platforms.
• Ensure reliable operation without disturbance to other platform control networks.

Coordination with Engineering Subcontractor

• Lead discipline reviews and approve I&C deliverables.
• Provide technical guidance on ADNOC standards and SOW requirements.
• Ensure timely submission of deliverables.
• Monitor and close TQs/RFIs and action items from design reviews.

Vendor / OEM Interface (High Priority)

• Liaise with OEMs and vendors for compressor, dryer, and control systems.
• Review vendor datasheets, I/O lists, control logic, and alarm philosophy.
• Participate in FAT/IFAT/SAT and verify signal testing and interlocks.
• Coordinate integration between vendor UCPs and ADNOC Offshore automation systems.

Process Safety & Functional Integrity

• Participate in HAZOP, HAZID, SIL, and PHSER workshops.
• Implement process safety instrumented functions (SIF) and verify SIL levels.
• Confirm alarm priorities, trip settings, and shutdown logic align with Operations.

Brownfield / Construction Support

• Review instrument installation details for tie-ins to live systems.
• Prepare and review method statements for instrument replacement and cabling works.
• Support loop checking, function tests, and C&E testing during commissioning.
• Ensure compliance with ADNOC PTW and SIMOPS procedures.

Interface & Documentation Management

• Maintain instrument interface registers and system interconnection diagrams.
• Coordinate with Process, Electrical, and Mechanical disciplines for consistent signal and tie-in data.
• Ensure smooth handover of as-built I&C documents and asset register updates.

Key Deliverables

• Updated instrument index and datasheets
• Control logic diagrams and C&E matrices
• Vendor package integration reports
• FAT/SAT and loop-check records
• As-built instrumentation drawings and signal lists
• Interface and tie-in registers
