Power Plant

JML has strong background and track record in Plant Maintenance. Over the last 20 years, we successfully completed several projects related to Oil-Fired, Coal-Fired, Gas-Fired, Combined Cycle, Cogeneration, Diesel and Waste-to-Energy Power Plants.

Power Plant Maintenance – Overview

JML is a leading maintenance contractor and serves as the single-source provider for all of your Power Plant Maintenance, Brownfield Modernization, and Operational needs. We specialize in both Captive Scale and Utility Scale (Over 700 MW) maintenance projects with a diverse range of services such as reverse engineering, procurement, fabrication, construction, and asset-maintenance activities at all stages of a power plant’s life-cycle.

JML has diligently developed its technical know-how through industry collaborations and in-house capabilities. This has enabled us to successfully complete projects with a combined capacity of over 6.9GW in ASEAN and GCC countries.

Our area of expertise in Power Plant maintenance covers:

  • Overhaul of Steam & Gas Turbines (M501D, M501F, M701D, M701F, GE270 T732)
  • Replacement of Boiler Pressure Parts (Superheater, Reheater Cycle, Water Walls, Drum Internals)
  • Routine and Predictive Plant Maintenance
  • Annual Outage & Shut Down Maintenance
  • Brownfield (BOP-Balance of Plant) System EPC Projects
  • Operations Support and Maintenance Term (LTSA) Contracts
  • Electrical & Instrumentation upgrading works
  • Plant Deconstruction and Demolition Works
