well as its CSI 6500 Machinery Health Monitor. Te CSI 6500 will enable HEA to detect turbine problems before they become critical by delivering comprehensive, real-time information that includes prediction, protection and performance monitoring, all fully integrated with the Ovation control architecture. With phase one completed and the combustion turbine back in operation, phase two is now under way. Emerson is further expanding the plant’s Ovation system, providing direct control and monitoring of the upgraded HRSG, burner management system, feedwater and water treatment systems, substation equipment and balance-of-plant processes. Te Ovation system will also provide supervisory control of the new steam turbine.

Alstom has been awarded two long term service agreement (LTSA) contracts for GT13E2 gas turbines in the Ivory Coast and Jordan. Te contract for the Azito power plant in the Ivory
Coast covers a 15-year period and includes the delivery of spare parts, reconditioning services and inspection supervision for the gas turbines and generators. Te contract for the Samra III power plant in Jordan spans a ten-year period and includes the delivery of new and reconditioned parts as well as supervision manpower for the execution of major inspections on all three GT13E2 units installed at the plant. Te Azito power plant, owned by Azito Energie, consists of two GT13E2 gas turbines operating in single cycle mode and is located close to the country’s capital Abidjan. Te plant provides 288 MW of electric power to the grid and accounts for approximately 35 per cent of the total electricity production in the Ivory Coast. For the Samra III power plant, owned by Samra
Electric Power, Alstom has already provided two GT13E2 gas turbines and will commission the third turbine, generator and auxiliaries by summer 2013.
In addition Alstom is currently supplying a steam tail to convert the existing Samra III 285MW single cycle to a combined cycle power plant. Tis conversion will increase the plant’s power generation capacity by an additional 143MW and is scheduled to enter commercial operation in 2015.
Hans-Peter Meer, senior vice president of Alstom Termal Services, said: “Tese new service contracts confirm Alstom’s strong position in servicing and maintaining gas turbines and generators. Both the Azito and Samra power plants are located in regions with extreme climate conditions where reliable power generation is key. Alstom’s technology, solutions and services support our customers’ needs in these regions and we are committed to further building strong relationships with the local power producers.”

Increased ratings for gas generator sets “These new offshore generator sets
aterpillar has launched new, higher-rated Cat 12CM32C and 16CM32C generator sets, offering industry-leading power densities. Designed specifically for offshore drilling and production applications including drillships, semi-submersible rigs, FPSOs and production platforms, these generator sets offer 560 brake kiloWatt (bkW) per cylinder, a 12 per cent increase over the previously available models. The 12 cylinder option offers a power rating of 6,720 bkW at both 720 and 750rpm; the 16 cylinder power rating is 8,960bkW at both 720 and 750rpm.

provide our customers with significantly improved power to meet the rigorous demands of ultra-deepwater drilling and other offshore applications,” said Will Watson, Caterpillar Global Petroleum offshore product manager. “The industry- leading power density offered by these generator sets further demonstrates our commitment to developing robust, reliable power solutions that will help operators get the most out of their vessels and their production operations,” he added. The CM32C generator sets incorporate

years of proven component reliability and durability in the offshore industry and meet IMO Tier II emissions standards. According to the company, they also feature a well thought-out complete package solution to enhance ease of installation and reduce complexity. The new generator sets allow for customisation options to meet exact customer specifications and reduce installation time, too. Manufactured in Kiel, Germany, the new higher output 12CM32C and 16CM32C generator sets will be available later this year. ●
