Renovation of the facility

We conduct the facility renovation work against the equipment showing the performance deterioration after the long-term use or against the facility trouble by the equipment failure.

Renovation of the exhaust duct of the gas turbine

Renovation work for the generator circuit breaker

Renovation of the oil circuit breaker to the VCB

Renovation of the AVR

You can renovate to the new control panel with the same functions of the existing pane by using new parts.


  1. On-board control panel - Before the renovation

  2. On-board control panel - After the renovation

Inspection tool

We develop and apply various types of maintenance tools in order to effectively support on-site inspection, check and measurement work. Without such tool, such works becomes very difficult and complicated. It becomes possible to increase opportunities for application by using the maintenance tool also for the inspection and diagnosis service items (menus) whose works had been conventionally difficult implement within the limited given work time, etc. This also allows us to provide high quality services to more customers. Further, we have been effectively securing safety and improving services using a specialized maintenance tools to meet customers' requests of reducing the facility downtime due to maintenance work.
