Lead Instrumentation & Control Engineer (Offshore Project)

Role Purpose

Lead and manage all Instrumentation & Control (I&C) engineering activities for the IA/PA Upgrade Project.

Ensure full compliance with ADNOC Offshore standards, seamless integration of new compressor-package control systems with existing DCS/ESD/F&G/PMS/ECMS, and coordination across Process, Electrical, and Mechanical disciplines through the Engineering Subcontractor and OEMs

Key Responsibilities (Project Specific)

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

• GE Fanuc / Emerson F&G

• 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

• Bachelor’s Degree in Instrumentation / Control / Electrical Engineering.

• ADNOC Offshore approval (or eligible).

• Functional Safety (SIL) and Hazard Study training preferred.

• PMP or equivalent certification advantageous.

Experience

• 15 years of EPC Oil & Gas I&C experience.

• Minimum 5 years in ADNOC Offshore brownfield projects.

• Strong background in compressor package control and automation integration.

• Experience with vendor/OEM coordination and FAT/SAT activities.

• Proven capability in design review and engineering subcontractor management
