Yugadanavi is a 300 MW combined-cycle power plant owned by LTL Holdings and operated by West Coast Power Limited. The facility comprises of two 100 MW General Electric Frame 9E gas turbines and a 100 MW General Electric SC5 steam turbine, together with two NEM heat recovery steam generators. Utilizing heavy fuel oil (HFO) or diesel oil (DO) as energy sources, Yugadanavi is capable of supplying the country’s main electricity grid with more than 300 megawatts of power while running at full load. During the period of internship, I had the opportunity to participate in an extremely rare power plant major inspection (MI) where one of the gas turbines, HRSGs, and the steam turbine were overhauled. During the MI, I was able to cooperate with so many highly experienced local and foreign specialists as more technical and skilled workforce had been recruited for the job.

Main areas I worked in:

• Gas turbines (GT), Steam turbine (ST) and auxiliaries
• NEM Heat Recovery Steam Generators (HRSG)
• Cooling towers (CT)
• Fuel oil and water treatment plants (FOTP and WTP)
• Treated and untreated HFO and DO storages
• Fuel unloading station and loboratory
• Auxilary boilers
• Control room and switchrooms

Some opportunities I had during my internship:

• Work with Mark VI interface and control room operations.
• Work with work permit systems such as LOTO and other power plant safety systems.
• Participate in gas turbine disassembly and have hands-on experience with various tools.
• Pump shaft alignment using advanced SKF alignment tools
• Warehouse and tool room management and issuing of tools
• Assembling and calibrating of turbine rotors and other shafts
• Overhead hoist operations and lifting equipment safety tests
• Collaborating with foreign technicians from Masaood John Brown (UAE), and SKF (USA)
• Participate in non-destructive testing (NDT) of turbine and compressor blades.
• Participate in pressure gauge calibration and manual, automated, and pneumatic valve repairs
