Position overview

QatarEnergy is seeking an experienced Sr Commissioning Engineer (Subsea, Umbilical & Pipelines) to oversee all subsea pipeline, flowline, and umbilical commissioning activities associated with the Bul Hanine Redevelopment Project and other offshore initiatives. The position covers full-cycle commissioning—from engineering and planning through offshore execution and final handover—and requires strong leadership in managing subsea commissioning campaigns safely and efficiently.

Client: Major Oil & Gas Operator – Offshore Operations Department
Location: Doha, Qatar (HQ) – Offshore assignment after 15 months
Contract duration: 36 months (renewable)
Rotation (post–15 months): 29 days ON / 27 days OFF

Project overview

About the project:
Qatar’s largest and one of its most strategic offshore oilfields, located approximately 100–120 km east of the Qatari coastline in the Arabian Gulf. The field has been in production since 1972 and is undergoing a major, multi-billion-dollar redevelopment program driven by QatarEnergy to extend field life, increase production capacity, and upgrade offshore infrastructure.

Key facts about the redevelopment include:

• A major $4 billion+ EPCI expansion program awarded to leading international contractors, including China Offshore Oil Engineering Co. Ltd (COOEC) for extensive offshore facilities and pipeline installations.
• The redevelopment aims to boost oil output and modernize the field, as Bul Hanine remains central to Qatar’s long-term energy strategy.
• Scope includes installing new offshore platforms, subsea pipelines, cables, and retrofitting existing assets, with more than 60 offshore facilities and 40 subsea pipelines/cables in scope.
• The project seeks to raise production significantly (from ~40,000 b/d to up to 95,000 b/d) and includes drilling approximately 150 new wells and installing 150 km of new subsea pipeline.
• This major expansion underscores Qatar's commitment to long-term offshore asset integrity, production sustainability, and infrastructure modernization.
