ABB was responsible for complete engineering services, construction supervision and commissioning of the electrical systems, as well as for staff training. A consortium comprising Suez Energy International, Mitsui, Ras Girtas Power Company, and Qatar Petroleum developed the plant, which sells water and electricity to the local utility, Kahramaa.
Very early in the tendering stage the EPC Hyundai Engineering and Construction supported by Suez/Mitsui signed a cooperation agreement with ABB, due to the highly complex nature of the electrical systems in the project. This was to limit their risk and was a direct result of ABB’s excellent track record in Qatar with Kahramaa. Ras Laffan was the third large project ABB has successfully completed in the country, after Ras Abu Fontas B2 in 2008 and Quatalum in 2009.
ABB products make up 71 percent of the hardware scope of supply, and ABB resources constitute 67 percent of the services. Total investment for the power and desalination plant amounts to $3.7 billion. ABB's project management was based in Mannheim (Germany), which during the engineering phase had to coordinate design offices in Abu Dhabi, Kosice (Slovakia), Baden (Switzerland) and the general basic design with offices in Seoul (Korea). A total of 41 factory acceptance tests held in the span of 94 days were successfully completed. Logistical challenges included 28,700 square meters of freight managed in some 61 shipments.
ABB's Swiss operations supplied some of the largest substations in the Middle East region for this project, including 31 bays of 400 kV gas-insulated switchgear (GIS), 12 bays of 220 kV GIS and 12 bays of 132 kV GIS, as well as associated systems, such as IEC 61850 substation automation, control, protection, telecommunication and auxiliary systems. ABB and its subcontractors performed 200,000 man-hours of work within the three years between go-ahead and hand-over.
ABB engineers and technicians from around the globe, including Germany, Switzerland, the USA, Canada, the Philippines and Korea helped complete this demanding project.
Following the hand-over, Hyundai project management commented: “Hyundai and ABB have pulled together to achieve the common targets for this project. Most of our plans have been completed successfully. We have mastered difficult and serious risks with the help of our strong cooperation and proper coordination, in spite of many unexpected obstacles and interruptions from the start-up until now, the finish. We are grateful to ABB and ABB staff for the positive cooperation and assistance, which proves ABB’s reputation and capability as a highly qualified company in the field of power systems worldwide.”
