Front End Engineering Design for the NCTL replacement

Back to overview

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.
