HOUSTON, Aug. 7 -- Johannesburg-based gas supplier Transnet Ltd. (previously Petronet) has awarded a €40 million contract to Siemens Energy, Erlangen, Germany, to supply automation controls for Transnet's planned 700-km multiproduct pipeline in South Africa.
Siemens will supply SCADA, telecoms, automation, a management information system, and security systems. Equipment includes a master control center with backup control center, automation for pumping stations, intake and delivery stations with accumulation tank facilities, and block valve stations.
The 11.5 billion rand ($1.5 billion) pipeline, scheduled to become operational in 2010, will transport gasoline, diesel, and jet fuel from Durban to the country's industrial and business center in the Johannesburg area of Gauteng province to meet that area's growing fuel demand.
Designed to debottleneck the current 600 km products transportation system, the new pipeline would replace and enlarge the existing 520 cu m/hr Durban-to-Johannesburg pipeline, which transports products to Johannesburg from the two Durban refineries on the coast and from imports. When completed, the new pipeline will have a capacity of 1,000 cu m/hr, expandable to 3,000 cu m/hr.
As planned, the system will consist of three sections: 545 km of 24-in. trunkline from Durban to Jameson Park in KwaZulu-Natal and Gauteng provinces; 77 km of 16-in. pipeline from Jameson Park to Langlaagte, through Alrode, in Gauteng province; and 88 km of 16-in. from Kendal to Waltloo in Gauteng and Mpumalanga provinces.
The Spie Capag consortium of Cergy Pontoise, France, will lay the pipeline, and a joint venture of Arup and WorleyParsons was named to perform engineering, procurement, and construction management.
