WAPA said maintenance on three Wartsila generators at Randolph Harley plant was completed
The Virgin Islands Water and Power Authority said on May 11, 2021, that inspection and maintenance work had been completed on three Wartsila generators at the Randolph Harley Power Plant on St. Thomas.
WAPA said production maintenance personnel, working under the guidance of Wartsila Engineering, inspected and maintained components on each engine. The first engine overhaul took about 10 days in 12-hour shifts, and after a lessons-learned review, work on the second and third generators was reduced to four days each.
According to the authority, turbochargers on each engine were replaced, cooling and lubrication systems were inspected, and vocsidizers, which it described as equipment that ensures clean air emissions, were opened, serviced and repaired.
WAPA said the three engines provided 21 megawatts of power to the St. Thomas-St. John district using liquefied petroleum gas as fuel. The authority said the units had generated more than 222,000 megawatt-hours of electricity since entering service in April 2019.
The release also identified maintenance, electrical, welding, instrument, building and grounds, automation and garage personnel who took part in the work.
