Project Overview
Fairtex executed isolation and decommissioning support activities for GMVH infrastructure within OML 58 for TOTAL E&P Nigeria Limited. The scope involved coordinated pipeline and process system intervention activities within an active brownfield operating environment requiring controlled lifting operations, piping isolation, and phased construction execution.
Execution activities were coordinated within live operational facilities requiring controlled access management, lifting supervision, piping integrity preservation, and shutdown-sensitive intervention planning.
The Challenge
The project involved isolation and decommissioning support across existing hydrocarbon handling infrastructure within an operational asset environment. Existing piping systems, process interfaces, and access limitations required careful execution sequencing to minimize operational disruption and maintain safe work boundaries.
Operational risks included:
- Brownfield construction exposure within active facilities
- Pipeline isolation and hydrocarbon containment requirements
- Heavy lifting coordination within congested process areas
- Shutdown-sensitive intervention scheduling
- Personnel and equipment interface management
- Environmental and operational safety compliance requirements
Our Approach
Fairtex deployed a phased execution methodology combining site preparation, piping isolation support, lifting coordination, mechanical intervention, and controlled decommissioning activities. Work fronts were aligned with operational access requirements and permit-controlled execution procedures.
Visible site activities included:
- Pipeline handling and spool installation support
- Mechanical isolation activities
- Heavy equipment mobilization and lifting operations
- Field construction coordination
- Process piping intervention
- Brownfield execution management
Phased Delivery
Assessment and Engineering Review
Existing infrastructure conditions, access constraints, and intervention interfaces were reviewed to support execution sequencing and operational coordination.
Mobilization
Construction personnel, lifting equipment, piping materials, and support tools were mobilized in accordance with site safety and operational requirements.
Isolation and Intervention
Mechanical isolation and piping intervention activities were executed under controlled field supervision with coordinated lifting and alignment operations.
Decommissioning Support
Decommissioning support activities were performed in phases to maintain operational continuity while enabling infrastructure modification and system separation requirements.
Validation and Handover
Completed intervention activities were verified through site inspections, operational reviews, and phased handover coordination with client representatives.
Outcome
The project was completed under controlled brownfield execution conditions supporting safe infrastructure isolation and decommissioning activities across the OML 58 asset environment.
Execution delivery contributed to:
- Reduced operational disruption during intervention activities
- Controlled piping isolation and infrastructure handling
- Improved worksite coordination across multiple field activities
- Maintained operational safety compliance during execution
- Structured decommissioning support within active facilities
