Loops Check Commissioning Supervisor

The Loop Check Commissioning Supervisor plays a central role in ensuring that all instrumentation and control loops on the cracker unit are installed, tested, and commissioned in accordance with project specifications, industry standards, and the EPCm contractor’s procedures. This position bridges construction, commissioning, and operations, ensuring a safe and seamless transition from mechanical completion to start-up.
You’ll be part of a multidisciplinary commissioning team, coordinating closely with EPCm partners, vendors, construction contractors, and the client’s operations group.

Key ResponsibilitiesLoop Check Execution & Coordination

• Lead and supervise daily loop-checking activities for instrumentation and control systems across the cracker unit.
• Review loop folders, P&IDs, I/O lists, cause & effect matrices, and instrument datasheets to ensure readiness.
• Validate that all loops—from field devices to DCS/PLC—are correctly installed, calibrated, and functionally tested.
• Coordinate with construction teams to resolve punch items, incomplete installations, or technical discrepancies.

Commissioning Management

• Support the development and implementation of commissioning procedures, test packs, and loop-check methodologies.
• Ensure all loop checks are executed in line with project commissioning plans, EPCm standards, and client requirements.
• Track progress using commissioning management systems (CMS) such as WinPCS, MCPlus, or equivalent.
• Participate in system walkdowns, punch list creation, and sign-off for mechanical completion and commissioning milestones.

Technical Leadership

• Provide technical guidance to technicians and subcontractors performing loop checks and instrument testing.
• Troubleshoot instrumentation, control logic, and communication issues between field devices and control systems.
• Liaise with DCS/PLC vendors during loop testing, logic verification, and functional testing.

Safety & Compliance

• Promote a strong safety culture and ensure all loop-checking activities comply with site HSE rules and Belgian regulatory requirements.
• Ensure all work is performed under appropriate permits and risk assessments.
• Verify that documentation meets project QA/QC standards and regulatory expectations.

Interface & Communication

• Act as the primary interface between commissioning, construction, EPCm engineering, and operations for loop-related issues.
• Report daily progress, constraints, and resource needs to the Commissioning Manager.
• Support handover documentation preparation for operations, including loop test records and as-built updates.

Required Qualifications & Experience

• Technical degree in Instrumentation, Electrical Engineering, Automation, or related discipline.
• Extensive experience in loop checking and commissioning on large petrochemical, refinery, or gas processing projects.
• Strong understanding of instrumentation, control systems, DCS/PLC architecture, and fieldbus technologies.
• Familiarity with EPCm project environments and multi-stakeholder coordination.
• Experience with commissioning management software and digital loop folders.
• Strong communication skills in English; knowledge of Dutch or French is an advantage.
• Proven ability to lead teams in a high-paced, safety-critical environment.

Preferred Attributes

• Hands-on, detail-oriented approach with a strong sense of ownership.
• Ability to interpret complex engineering documentation and resolve technical issues efficiently.
• Comfortable working in multicultural, multidisciplinary teams.
• Proactive mindset with a focus on safe, high-quality execution.
