Operation & Maintenance of Power Plants
Specialist maintenance companies provide comprehensive solutions
As downtime costs money, maintenance strategies have to be carefully planned and involve experienced specialists. Eugene McCarthy reports.

R
otork Site Services in Australia has completed the comprehensive workshop service of 28 Rotork IQ valve actuators within the critical four-week timescale dictated by a
power station shutdown. T e actuators have been installed at the 487
MW Pelican Point combined cycle gas turbine (CCGT) power station near Adelaide in South Australia for seven years. On-site facilities to carry out the work were limited, so a decision was made to remove the actuators and transport them to Rotork’s own fully equipped workshops at Ballarat, some 600 km from the power station.
Return, re-fi t, re-commission Rotork took complete control of the project, hiring a truck to transport the actuators rather than relying on a third-party when the precise timing of activities would not be known. T e project was divided into four, week-long portions, involving removal, workshop service, return and refi t and re-commission. T e actuators required only relatively minor
repairs, mainly caused by environmental exposure. In all cases, only genuine Rotork parts were used, enabling the actuators to be tested and returned in as-new condition. All the work was completed within the strict timescale allowed, ensuring that Rotork Site Services’ performance would not delay the power station’s plans for re-starting.
