Trans Niger Pipeline Loopline
The Trans Niger Pipeline (TNP) transports around 180,000 barrels per day of crude oil to the Bonny Export Terminal and is part of the gas liquids evacuation infrastructure, critical for continued domestic power generation (Afam VI power plant) and liquefied gas exports. The loopline project creates an alternative route to avoid sabotage, bypassing an area where theft and illegal refining have been common. In addition, the project will install monitoring systems to detect any intrusion or leak. The pipeline will not be completely covered to allow security patrol boats to quickly access all pipeline sections.
|Key facts||Trans Niger Pipeline Loopline|
|Location:||Ogale, Alakiri, Cawthorne Channel and Bonny|
|Interests:||Shell Petroleum Development Company Ltd (SPDC) is the joint venture (JV) operator of an unincorporated JV with a 30% interest.|
|Partners:||Nigerian National Petroleum Corporation (NNPC: 55%), Total E&P Nigeria Ltd (10%), and Nigerian Agip Oil Company (NAOC: 5%)|
The project aims to secure the evacuation of crude from assets in the eastern part of the Niger Delta', and of natural gas from the Gbaran, Agbada, Okoloma and Alakiri gas plants to the Bonny terminal. After completion it also allows for more easy access to maintain the infrastructure.
The project consists of three parts:
1. 12.5 km 30” pipeline from Ogale to Eleme/Ogu Bolo over land terrain.
2. A 25.5 km 30” pipeline from Eleme/Ogu Bolo to the Cawthorne Channel Junction Manifold and a 2.4 km 8” pipeline from Alakiri to Ojikiri spurline; both over swamp terrain.
3. A 20km 30’’ pipeline and a 20 km 24” loop pipeline leg from Cawthorne Channel Junction Manifold to Bonny Oil & Gas Terminal; both over swamp terrain.
Final investment decision was taken on the project on June 14, 2013. The contracts for the first package were signed on July 3, 2013 with the KAZTEC Engineering Limited. The award of packages two and three is awaiting Nigerian National Petroleum Corporation Board approval.
Regulatory approval has been granted for the environmental impact assessment report.
TNPL is the first project in Nigeria to procure line pipes from a local pipe mill as part of SPDC’s efforts to provide local jobs and business. The project invested significantly to improve the quality and safety standards of the local mill to meet Shell standards.
The project includes a system that will use fibre-optic sensing technology to detect intrusion into the pipeline right of way and leaks. It can be configured to suit different environments, whether solid ground or swamp. It relays real-time information to a control centre.
Environment and society
Specialists from the project carried out an environmental impact assessment together with affected communities and regulatory authorities. Measures to limit the impact of activities include using a horizontal directional drilling technique that goes below major rivers and roads, rather than dredging the rivers, reducing social-economic impact and disruption to wildlife.
The project employs local people directly and generates business for local suppliers and contractors.
Communities are expected to also benefit from investment in programmes that they can choose under a scheme called the global memoranda of understanding.
