The successful candidate will oversee the commissioning of gas inlet and condensate facilities, as well as onshore subsea support equipment, ensuring safe execution, technical compliance and successful handover to Operations.

As a Commissioning Subsea Engineer, you will oversee the commissioning of the Inlet and Condensate facilities and onshore subsea support equipment, from engineering preparation through execution and start-up.

Main Responsibilities:

• Oversee the commissioning of systems and subsystems for the Inlet and Condensate facilities, ensuring proper handover to Operations.
• Supervise the preparation and scheduling of pre-commissioning and commissioning activities to achieve safe and timely Mechanical Completion (MC), Ready for Start-Up (RFSU) and Ready for Loading (RFL) milestones.
• Actively contribute to the development and review of pre-commissioning and commissioning engineering deliverables during the engineering phase.
• Ensure contractors comply with contractual requirements, project specifications and HSE standards.
• Supervise commissioning activities on site and manage interfaces between contractors, subcontractors and equipment vendors.
• Coordinate with Engineering, Contracting, Procurement, Construction and Operations teams to ensure progress towards final RFSU.
• Coordinate the witnessing of commissioning activities with Operations personnel and complete remaining commissioning activities following hydrocarbon introduction under SIMOPS (Simultaneous Operations) conditions.

• Minimum 10 years of experience in commissioning or process systems, including at least 5 years in senior commissioning roles.
• Proven experience in commissioning gas inlet, slug catcher and condensate stabilisation systems within LNG or gas-processing facilities.
• Strong technical knowledge of HIPPS, beach valves, subsea chemical injection, MEG systems and hydraulic power units (HPU).
• Solid background in process and control engineering, including the ability to read and interpret P&IDs, cause & effect matrices and control narratives.
• Experience in developing and reviewing commissioning procedures, test packs, punch lists, commissioning schedules and MC/RFSU/RFL dossiers.
• Proven track record in achieving Mechanical Completion (MC), Ready for Start-Up (RFSU) and Ready for Loading (RFL) milestones.
• Experience working under SIMOPS conditions, particularly during hydrocarbon introduction.
• Strong communication, coordination and leadership skills, with the ability to manage multiple interfaces in multicultural and multi-site environments.
• Ability to work under pressure and influence stakeholders through sound technical arguments.
