BridgeHedge Gas Network (BGN)
BridgeHedge Gas Network is a network of gas pipelines proposed by BridgeHedge which is aimed to monetize the abundant natural gas resources in the Oil and Gas rich Niger-Delta region of Nigeria. The Pipeline will supply natural gas to starving domestic and regional markets which will fuel economic growth and development in the region.
The first stage of the pipeline is the Federal Government of Nigerian planned East – North pipeline system. BridgeHedge is proposing to build, own and operate this pipeline through a Joint Venture between BridgeHedge and NNPC, the Representative of the Nigerian Government on the project.
The Pipeline is a backbone pipeline project which when completed will be at the core of energy security in Nigeria and Africa at large. We believe the BridgeHedge Gas Network system is critical to achieving energy security in Nigeria and the rest of Africa.
MAINLINE TRANSMISSION SYSTEM:
The natural gas mainline system is designed to be a grid system. A grid type transmission system is usually characterized by a large number of laterals or branches from the mainline, which tend to form a network of integrated receipt, delivery and pipeline interconnections that operate in, and serve major market areas.
The BridgeHedge Gas Network will begin from the Niger-Delta Oil and Gas Fields with gas gathering lines which will carry associated gas from oil fields to processing plants and then through assembling lines the gas will flow from the Gas Processing facilities to the main transmission line.
Route 1.0 Northern Network: Ajaokuta-Kaduna Kano (AKK) Pipeline: 40” X 187 Km pipeline from Ajaokuta – Abuja 40” X 193 Km pipeline from Abuja– Kaduna 40” X 65 Km pipeline from Kaduna – Zaria 40” X 238 Km pipeline from Zaria – Kano Total = 40” X 683 Km
2.0 Eastern Network: Qua Ibo/Calabar Ajaokuta Pipeline (CAP) system System (a): QIT-Obigbo-Node-OB/OB: 36” X 58 Km pipeline from QIT to Ikot Abasi 36” X 37 Km pipeline from Ikot Abasi – Ukanafun 36” X 44 Km pipeline from Ukanafun – Obigbo Node 36” X 81 Km pipeline from Obigbo Node to Ob/Ob Total = 36” X 220 Km System (b): Obigbo Node –Ajaokuta: 36” X 114 Km pipeline from Obigbo Node to Umuahia 36” X 124 Km pipeline from Umuahia – Enugu 36” X 180 Km pipeline from Enugu – Ajaokuta Total = 36” X 418 Km System (c ): QIT-Umuahia 24” X 43 Km pipeline from QIT to Okopedi 24” X 18 Km pipeline from Okopedi to Uyo 24” X 38 Km pipeline from Uyo to Ikot Ekpene 24” X 75 Km pipeline from Ikot Ekpene – Umuahia Total = 24” X 174 Km
Between the producing area, or supply source, and the market area, a number of compressor stations will be located along the transmission system. These stations will contain one or more compressor units whose purpose will be to receive the transmission flow (which has decreased in pressure since the previous compressor station) at an intake point, increase the pressure and rate of flow, and thus, maintain the movement of natural gas along the pipeline.
Compressor units that will be used on our natural gas mainline transmission system will be rated at 1,000 horsepower or more and will be of the centrifugal (turbine) or reciprocating (piston) type.
To address the potential for pipeline rupture, safety cutoff meters will be installed along our mainline transmission system route. Devices located at strategic points will be designed to detect a drop in pressure that would result from a downstream or upstream pipeline rupture and automatically stop the flow of natural gas beyond its location. SCADA (Systems Control and Data Acquisition) systems will provide monitoring staff the ability to direct and control pipeline flows, maintaining pipeline integrity and pressures as natural gas is received and delivered along numerous points on the system, including flows into and out of storage facilities.
We will build storage facilities at the end of the mainline transmission system, and in between. Our natural gas storage facilities will provide inventory management, supply backup, and the access to natural gas to maintain the balance of the system. Two of the most important characteristics of our storage reservoir will be the capability to hold natural gas for future use, and the rate at which natural gas inventory can be injected and withdrawn.
Our centers will also provide unique services that will help expedite and improve the natural gas transportation process overall, such as our Internet-based access to natural gas trading platforms and capacity release programs. We will also provide title transfer services between parties that buy, sell, or move their natural gas through the center.
