In 1991, a feasibility report conducted by the World Bank on supplying Nigerian gas to West African markets deemed that a project was commercially viable.
[5][6] Gas deliveries were expected by the end of 2009 after commissioning regulating and metering stations in Takoradi and Tema, Ghana, Lagos Beach, Nigeria, Cotonou, Benin, and Lomé, Togo in May 2008.
[7] However, deliveries were postponed again due to an irregular amount of moisture found inside the onshore gas pipeline.
The diameter of the offshore pipeline is 20 inches (510 mm) and the capacity is 5 billion cubic meter (bcm) of natural gas per year.
[4][14] The pipeline is owned by West African Gas Pipeline Company Limited (WAGPCo), a consortium of Chevron (36.7%), Nigerian National Petroleum Corporation (25%), Royal Dutch Shell (18%), Volta River Authority of Ghana (16.3%), Société Togolaise de Gaz (SoToGaz - 2%) and Société Beninoise de Gaz S.A. (SoBeGaz - 2%).
[16] Environmental group Friends of the Earth has criticized the project, after local communities in Nigeria complained it would damage land, destroy livelihoods and pollute fishing areas.
