The Role?

The Pipeline Pre-Commissioning Supervisor is responsible for overseeing and executing all site-level pre-commissioning activities on pipeline systems, including cleaning, gauging, flooding, hydrotesting, drying, nitrogen purging, inerting, and intelligent pigging operations. This role requires extensive hands-on experience with high-capacity nitrogen membrane systems and the coordination of multidisciplinary teams to safely deliver pipeline systems ready for commissioning.

Main Responsibilities & Key Result Areas

• Supervise the full suite of pre-commissioning activities, including:
• Pipeline flooding, cleaning, and gauging (FCG) - Hydrostatic testing (HT)

- Dewatering and air drying

- Nitrogen purging/inerting using membrane and liquid nitrogen systems

- Intelligent pigging (ILI) and baseline tool runs

• Lead onshore and offshore execution at both launcher and receiver ends
• Ensure the proper setup and functional testing of large pre-comm spreads, including chemical
• Injection units, hydrotest pumps, filtration skids, nitrogen membranes, air dryers, and compressors.
• Enforce pre-commissioning procedures in line with DNVGL-ST-F101 and project-specific specifications.
• Direct field technicians in rig-up, pig loading/launch, spread ramp-up, pressure control, and pig receiving operations.
• Monitor real-time data on pig speed, pressure, chemical dosing, and water quality to ensure compliance with control points.
• Manage safety during high-pressure operations and coordinate Job Safety Analyses (JSAs), toolbox talks, and HSE audits.
• Interface with project engineering teams, clients, and third-party inspection teams.
• Participate in contingency planning for events such as stuck pigs, pressure anomalies, or spread malfunctions. Requirements

• 8+ years of pipeline pre-commissioning experience, with at least 5 years in a supervisory role
• Proven track record running a large-scale nitrogen membrane spread.
• Strong technical knowledge of pigging operations, pipeline integrity testing, and seawater chemical treatment.
• Experience working with high-integrity clients (e.g., Qatargas, Saipem) and executing work under strict HSE systems. Behaviors and Personal Qualities

• Strong leadership, decision-making, and conflict resolution skills.
• Ability to work under pressure and in extreme environments (heat, offshore).
• Detail-oriented with a commitment to procedural discipline and safety.
