Wood Group GTS has completed a major inspection and lifetime assessment of a Siemens SGT-600 (GT10B) gas turbine for DONG Energy A/S at the H.C. Orsted Power Station, situated at Sydhavnen in Copenhagen, Denmark. The inspection included replacement of the stage 1 and stage 3 rotor blades with new parts produced through Wood Group GTS' Advanced Parts Manufacture (APM) program, as well as exchange of the exhaust diffuser and modifications to the air intake system to facilitate automatic downtime preservation of the gas turbine on shutdown.
During the inspection, Wood Group GTS also completed a lifetime assessment of the rotor which involved a detailed inspection of the gas turbine rotor at 80,000 operational hours, validating the integrity of the rotor for a further 60,000 operational hours. This service offers significant cost savings to the operator, when compared to the alternative option of rotor replacement at 120,000 equivalent operating hours.
