A 12,000-hour inspection and maintenance of the Wartsila generators at the Randolph Harley Power Plant was recently completed. Each of the three reciprocating internal combustion engines was taken offline, one at a time, to perform the scheduled maintenance and ensure continued reliable and efficient operations.
Under the guidance of Wartsila Engineering, WAPA production maintenance personnel worked around the clock to inspect and maintain various components on each of the power generating engines.
The work was carried out in 12-hour shifts for approximately 10 days on the first engine, following which a “lessons learned” meeting determined methods by which work on the two remaining generators could be carried out more efficiently and over a shorter period. The work on the second and third generators was subsequently reduced to four days.
In each instance, the engine’s turbochargers, which provide for the efficient operation of the units, were replaced. Cooling and lubrication systems were also inspected and the vocsidizers (equipment that ensures clean air emissions) were opened, serviced and repaired.
The Wartsila engines provide 21 megawatts of power to the St. Thomas-St. John District utilizing 100 percent LPG as its fuel source. These more efficient engines provide approximately the same power generating capability as the older gas turbines, while using half the volume of fuel. Since coming online in April of 2019, the three engines, which comprise the Wartsila power plant at Harley, have generated more than 222,000 megawatt hours of electricity.
Several WAPA employees worked tirelessly to ensure the success of the critical equipment outages required for the unit’s scheduled maintenance and inspection.
Through the leadership of Maintenance Manager Gabriel Dore, Maintenance Mechanical / Welding Supervisors Dana Joseph and Darryl Allen and Acting Electrical Maintenance Supervisor Trevor Liburd, all work was completed safely and on a timely basis.
