Norwalk, Connecticut, August 26, 2005 -- ABB, the leading power and automation technology group, said today it received a contract from Willbros West Africa Inc. for a supervisory control and data acquisition system (SCADA) and a common integrated communications system for a pipeline that will deliver gas from Nigeria to terminals in Benin, Togo and Ghana for power generation. The contract, estimated at US$9 million, is for a solution that will include an integrated local and wide area networking structure for VoIP telephone communication and SCADA control via satellite. This will enable communication and control between the remote control center, the compressor station and five regulation and metering stations for the facilities' SCADA, process control, safety and fire & gas systems. Cost of the overall project was not disclosed. "ABB was selected for its scope of supply and the ability to reduce overall project risk, construction schedule and cost by modularizing, installing and testing the systems before shipping them to Africa," said Gardiner Henderson of ABB. "This approach is preferred over shipping components separately because the replacement of any lost parts would be difficult and most likely would delay completion of the project." Henderson noted that ABB approached the customer's needs, drawing on the expertise of its operations in Calgary, Montreal and Houston. Work on the 620-kilometer long pipeline is scheduled for completion by December 2006. It is projected to initially carry 130 million cubic feet per day with a projected capacity of 470 million cubic feet per day. The pipeline will be owned and operated by West African Gas Pipeline Company Limited, whose shareholders consist of ChevronTexaco West African Gas Pipeline Ltd., Nigerian National Petroleum Corporation, Shell Overseas Holdings Limited, Takoradi Power Company Limited, Societe Togoliase de Gaz and Societe Bengaz. Henderson noted, "The West African Gas Pipeline project will reduce greenhouse gas emissions by contributing to a reduction in flaring associated with existing oil production in Nigeria. Air pollutants will be further reduced because natural gas will replace the use of fuels that are less "friendly" to the environment in power generation and industrial production." ABB ( is a leader in power and automation technologies that enable utility and industry customers to improve performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employees 103,000 people. The company's North American operations, headquartered in Norwalk, Connecticut, employs about 12,000 in manufacturing and other facilities.
