In order to find the best possible solution and to meet the customer's requirements, the whole turbo set was examined in detail via an engineering study. To optimize the complete water-steam cycle, the final scope included not only a SST-600 footprint turbine with new coupling, gearbox, and TURLOOP control and protection system, but also a footprint generator and new steam cycle components including preheater and condensate pumps.
Despite the rather extensive modifications on site, the footprint solution still was preferred to a new train or revamp because of shorter shutdown time due to the re-use of existing foundation, condenser, and other auxiliaries.
