The first of the four gas turbines for Petroliam Nasional Bhd’s (Petronas) cogeneration power plant in Pengerang, each weighing as much as an Airbus A380 superjumbo, has arrived in Johor. Arriving from Hamburg, Germany, it is set to begin commercial operations by mid-2017.
When it arrived at the Tanjung Setapa Material Offloading Facility within the Refinery and Petrochemical Integrated Development (Rapid) project site, the first Siemens SGT5-8000H gas turbine was received by representatives and management officials from the Johor port authorities, Petronas and the consortium of Siemens AG, Siemens Malaysia and MMC Engineering Services Sdn Bhd. The consortium was awarded the engineering, procurement, construction and commissioning contract for the 1,220 MW plant in May 2014.
According to Siemens Malaysia, the SGT5-8000H, said to be the most powerful gas turbine in commercial operation today, measures 13.5 metres in length, 5.5 metres in height and 5.9 metres in width, and arrived after a four-week trip.
The company said each gas turbine unit comes with a waste-heat recovery steam generator (HRSG), associated mechanical and electrical systems and the instrumentation and control system. The steam produced in the HRSG will not only be partly used to supply up to 1,250 tonnes per hour of steam to various consumers within the Pengerang Integrated Complex (PIC), but will also be partly used to produce further electricity inside a triple stage steam turbine, hence optimising efficiency.
On completion, the cogeneration plant will have a total installed capacity of about 1,220 MW and will be one of the six associated facilities that will be developed within PIC.
