Proper overhaul and workshop maintenance are critical to maintaining engine reliability, operational efficiency, and long-term performance. Without timely intervention, wear and component degradation can lead to unexpected failures, costly downtime, and reduced system availability.
Keypower provides comprehensive overhaul, inspection, repair, and reconditioning services for marine and power plant gas and diesel engines, in full compliance with OEM specifications and international engineering standards.
Our scope includes complete engine overhauls, partial refurbishments, component-level inspections, precision measurements, and reassembly in accordance with strict technical requirements. All processes are carried out using appropriate tools, calibrated equipment, and proven engineering practices.
With an experienced team of field service engineers and technicians, we ensure safe execution, accurate diagnostics, and high-quality workmanship at every stage of the overhaul process. Our teams operate both on-site and in workshop environments, depending on project requirements.
Upon request, we define customized maintenance scopes based on detailed inspections and operational assessments. By evaluating the actual condition of engines and auxiliary systems, we develop optimized maintenance strategies tailored to each installation.
This approach enables operators to achieve:
Failure analysis related to overhaul works
Root cause analysis after engine damage
Fuel injection system inspection and adjustment
Cylinder liner landing surface inspection and corrective machining
Major maintenance and engine restoration works
Corrective workshop work to improve engine reliability
Turbocharger inspection and service within overhaul scope
