Siemens Energy Performed First Remote Outage for Steam Turbines

June 3, 2021
Kagoshima, Japan

  • Successful remote outage for a NPP in Sendai, Japan – the first worldwide for Siemens Energy
  • Demonstrates the project team’s commitment and dedication in ensuring that customer’s needs are met despite the time-zone difference
  • Underscores the strengths of digitalization backed by real-time technical support when on-site assistance could not be rendered due to COVID-19 travel ban


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. 

The customer’s high demand for data security worked very well in underscoring Siemens Energy’sstrength in cybersecurity and enhanced digital capabilities that include setting up live streams forimmediate support and monitoring of works. A joint outage approach was also carried out in whichthe project team from Germany worked the night shifts to ensure availability for the customerthroughout their normal work hours during the day. By accommodating the customer’s time andkeeping up the service support, it demonstrated the project and local teams’ and commitment andfervor to exceed expectations for this contract that was awarded to Siemens Energy. This furthersolidifies the long-standing relationship and trust that is shared between all parties.

Due to the travel ban imposed from the COVID-19 pandemic, onsite supervision could not beperformed and were fully dependent on total remote settings and virtual alignment. Byunderstanding the customer’s pain points, Siemens Energy managed to resolve the issues with itstechnological competencies and transformed challenges into opportunities that led to thisbreakthrough outage performance as the first global success in exclusively remote approach.

“This outage inspection has been carried out for about half a year not only under immigrationrestrictions from overseas but also under strict prevention of COVID-19 infection. We would like tothank Marubeni Utility Services and Kyushu Electric Power for their cooperation in completing theconstruction without delay over this long period of time. In the future, we will make use of thisknowledge and achievements to further improve our services and strive to win the trust of ourcustomers.” said Mr Yasuhiko Otsuki, Managing Director of Siemens Energy K.K., Japan.
