business introduction
Orbis provides commissioning, routine maintenance, preventive overhaul,
and retrofit services for domestic and overseas power plants.
With accumulated expertise and field experience, we enhance plant reliability and operational efficiency through high-quality maintenance solutions.
Backed by specialized capabilities in instrumentation, control, and electrical systems,
Orbis is committed to delivering Zero-Failure Operation and ensuring safe, reliable plant performance.
Regular preventive inspections and predictive diagnostics to identify and address potential issues in power plant equipment before failures occur. When abnormalities are detected, our team takes immediate corrective action to minimize downtime, and in the event of unexpected failures, we ensure rapid recovery and repair to restore normal operation. With accumulated expertise and advanced technical capabilities, Orbis delivers optimal maintenance quality and operational efficiency for every power facility.
In accordance with long-term maintenance schedules and technical standards, power plant equipment is shut down to perform disassembly, inspection, testing, and restoration of major systems and components. With experienced professionals and proven maintenance expertise, a systematic pre-planning and quality management process is implemented to enhance efficiency and reliability throughout the overhaul period. Through structured preventive maintenance, we contribute to improved equipment availability and optimized plant performance.
At the final stage of power plant construction, unit and integrated commissioning are carried out to complete the plant for stable commercial operation. During the commissioning period, we perform system and equipment testing, preventive inspections,
and emergency repairs to ensure smooth transition to full-scale operation. By developing detailed maintenance procedures and systematically managing initial operation data such as vibration measurements, we help secure the reliability and integrity of the
facility for long-term performance.
