The first remote outage was successfully performed and completed for 2 units of an 890MW SendaiNPP in Japan together with Marubeni Utility Services, which is a partner of Siemens Energy in Japan’snuclear industry while Siemens Energy Japan provides strong support from Sendai. As SiemensEnergy is the Original Equipment Manufacturer (OEM), the project team was entrusted to supervisethe inspections performed by Nishinippon Plant Engineering and Construction Co Ltd, a subsidiary ofKyushu Electric Power Co Inc, for two units of the LP Turbine. The works involved assembling anddisassembling the turbines under close supervision, fact-finding inspection and remoterecommissioning including vibration assessment during shut down and restart. Remote balancinghas been duly planned but was not needed during restart due to the good vibration behavior of theturbine.
