The 678 kilometer West African Gas Pipeline (WAGP) links into the existing Escravos-Lagos pipeline at the Nigeria Gas Company’s Itoki Natural Gas Export Terminal in Nigeria and proceeds to a beachhead in Lagos. From there it moves offshore to Takoradi, in Ghana, with gas delivery laterals from the main line extending to Cotonou (Benin), Lome (Togo) and Tema (Ghana). The Escravos-Lagos pipeline system has a capacity of 800 MMscfd, and the WAPCo system will initially carry a volume of 170MMscfd and peak over time at a capacity of 460MMscfd.
The main offshore pipeline runs East to West at an average water depth of 35 metres though some sections such as the south east of Ghana, south of Lome and the Benin – Nigerian frontier ranges between 50 to 70 meters. Its range from the coast is as varied as the depth. South of Cape St. Paul in Ghana, it is as close as 3.5 nautical miles (6.5 kilometres) while at its widest section south of Winneba also in Ghana, it is 17.5 nautical miles (32.5 kilometres). The ranges of the Tees from the coast are approximately as follows:
Cotonou - 7 nautical miles (13 Km).
Lome - 10.3 nautical miles (19 Km).
Tema -7.8. nautical miles (14 Km).
The main pipeline is 20 inches in diameter. Cotonou and Lome laterals are 8 inches respectively while the Tema lateral is 18 inches. The termination point at Takoradi (Aboadzi) forms part of the main pipeline.
WAGP transports purified natural gas free of heavy hydrocarbons, liquids and water, ideally suited as fuel for power plants and industrial applications. Eighty-five per cent of the gas is for power generation and the remaining for Industrial Applications. The Volta River Authority’s Takoradi Thermal Power Plant in Ghana, CEB of Benin and Togo are WAPCo’s foundation customers.
