Project Characteristics

The MTR Project covers the three major SPDC Eastern Division oil trunklines:

  • Trans Niger Pipeline (TNP)
  • Greater Port Harcourt Swamp Line (GPHSL)
  • Nembe Creek Trunkline (NCTL)

The total length of the considered pipelines amounts to approx. 370 km. The pipeline sizes range between 6" and 36".

The project objective was to provide a cost effective design for the SPDC oil trunkline network. It should be capable of evacuating SPDC-E production safely and efficiently, with minimum impact to the environment with the following aims:

  • Restore pipelines rating and integrity
  • Ensure evacuation capacity for current and future production targets for the next 30 years
  • Reduce production deferment
  • Reduce environmental pollution
  • Manage the concurrent operations and tie-in sequence to ensure minimal disruption of crude production during transition from the current trunkline network to new lines.
