Project Introduction

Following the confirmation of an illegal third-party cut on the 14-inch Okordia–Rumuekpe Delivery Line at KP24.9 within Edeoha Community, immediate intervention became necessary to restore pipeline integrity and ensure safe production operations.

Greenspan Solution Limited was engaged to execute a Joint Investigation Visit (JIV) and carry out emergency pipeline repair using a PLIDCO clamp installation method. The project involved exposing the damaged section of the pipeline, conducting integrity assessments, installing a suitable repair clamp, recoating the affected section, and restoring the site to its original condition.

 

The successful completion of the repair reinstated the integrity of the pipeline while maintaining strict adherence to safety, environmental, and operational standards.

Engineering Insight
Timely intervention and the application of proven repair technologies are critical to preserving pipeline integrity, minimizing operational downtime, and ensuring the continued safe transportation of hydrocarbon products.

— Ajibefun Samuel, Project Engineer

Scope of Work

The project scope covered all activities required to safely expose, assess, repair, and restore the affected section of the pipeline.

Pre-mobilization inspection and certification of personnel and equipment
Securing Free-To-Operate (FTO) approval from the host community
Material collection and logistics coordination
Mobilization of personnel, equipment, and materials to site
Mechanical excavation to expose the defect location
Ditch setup and safety preparation
Plugging and containment of the leak point
Removal of existing coating and surface preparation
Installation and fit-up of the PLIDCO repair clamp
Bolt tightening and torque application
Recoating of the repaired pipeline section
Backfilling and site restoration
site setup
site setup

Working Process

The repair operation was executed through a structured engineering process designed to ensure safety, quality, and operational efficiency.

01
Step

Site Mobilization and Assessment

Personnel, equipment, and materials were mobilized to the site following the issuance of permits and community approvals. Toolbox meetings, hazard assessments, and preliminary inspections were conducted before work commenced.
02
Step

Excavation and Defect Exposure

Manual and mechanical excavation activities were carried out to expose the affected section of the pipeline. A Joint Investigation Visit (JIV) confirmed an illegal hacksaw cut located between the 12 o’clock and 1 o’clock positions of the pipeline.
03
Step

Clamp Installation and Integrity Restoration

The damaged section was de-coated and prepared for repair. A 14” × 14” PLIDCO clamp (Serial No. 6683005) was installed over the defect location, followed by bolting, tightening, and torqueing to specified requirements to restore pipeline integrity.
04
Step

Recoating, Backfilling, and Site Restoration

Following successful clamp installation, the exposed section was recoated for corrosion protection. The excavation was subsequently backfilled, safety accessories removed, and the site restored to acceptable environmental and operational standards before demobilization.

Project Outcome

The repair was completed successfully within the planned execution period with:

  • Zero Lost Time Incidents (LTI)
  • No environmental incidents recorded
  • One defect point successfully repaired
  • Full restoration of pipeline integrity
  • 100% completion of project scope
  • Successful site restoration and demobilization

HSE Performance Highlights

  • ero Fatalities
  • Zero Lost Time Injuries (LTI)
  • Zero Total Recordable Cases (TRC)
  • Zero Road Traffic Accidents (RTA)
  • Zero Security Incidents
  • 100% Compliance with Job Hazard Analysis (JHA)
  • 100% Personnel Medical Fitness Compliance

Conclusion

The JIV and clamping repair operation on the 14-inch Okordia–Rumuekpe Delivery Line at KP24.9 was executed safely, efficiently, and within schedule. Through effective planning, adherence to HSE requirements, and the deployment of qualified personnel and equipment, the damaged pipeline section was successfully repaired and returned to service.

The project demonstrates the importance of rapid response, sound engineering practices, and effective stakeholder collaboration in maintaining pipeline integrity and ensuring uninterrupted production operations.
